The Permaculture Guide to Covert Guerilla Gardening

Guerilla gardening is the act of cultivating plants in neglected, abandoned, or otherwise unused spaces, often without the official approval of the landowner. It’s a form of civil disobedience that transforms barren urban landscapes into lush, green areas teeming with life. But it’s more than that—it is a movement rooted in the ethical pursuit of food sovereignty, which seeks to empower communities to take control of their local food systems, and the fundamental right of individuals to grow their own food, ensuring that everyone has the ability to provide for themselves and their families.

In many urban areas, particularly in food deserts—regions where access to affordable, fresh, and nutritious food is scarce—the push to reclaim land for food production is both a necessity and a statement. These barren landscapes, often the result of economic disparity and poor urban planning, have forced food plants out of the places where people live, contributing to a cycle of poor health and food insecurity.

Guerilla gardening, especially when informed by permaculture (ecological garden design) principles, challenges this inequity by taking back underutilized spaces and transforming them into productive, sustainable gardens. It is an act of empowerment, asserting the right of communities to access and cultivate the land, even in the face of systemic obstacles.

For educational purposes, this guide will explore how someone would engage in covert guerilla gardening using permaculture techniques to create resilient, self-sustaining ecosystems that support both people and the planet.

Understanding Permaculture Principles

Permaculture is a design approach that mimics natural ecosystems to create sustainable and self-sufficient systems. It emphasizes observing the environment, using resources wisely, and working with nature rather than against it. By applying these principles, guerilla gardeners can create thriving, low-maintenance green spaces that support biodiversity and community resilience.

Key concepts include observing the site’s conditions (like sunlight, water flow, and soil health), selecting plants suited to the local environment, and designing for minimal waste and self-regulation. These strategies ensure the garden integrates seamlessly into its surroundings and can sustain itself with minimal human intervention. By harnessing permaculture principles, guerilla gardeners transform neglected spaces into productive ecosystems that benefit both people and the planet.

Practical Application of Some Permaculture Principles for Guerilla Gardening

Here are some permaculture design principles, along with tips for their practical application, that are especially relevant to guerilla gardening, where the goal is to create self-sustaining, low-maintenance green spaces in urban environments:

1. Observe and Interact

Principle: Spend time observing the site before planting. Understand the microclimate, soil conditions, and existing plant life.

Before planting, it’s essential to thoroughly observe the chosen site. Understanding the microclimate, soil conditions, and existing plant life is crucial for designing a successful garden. Observation allows you to identify natural patterns such as sunlight exposure, wind direction, and water flow, which can all influence plant growth. By interacting with the environment and paying close attention to these details, you can make informed decisions that will enhance the success of your garden. For example, planting shade-tolerant plants in areas with limited sunlight or choosing drought-resistant species for areas with minimal water access.

Practical Tips:

• Map the Area: Sketch a simple map of the site, noting areas of sunlight, shade, and wind exposure. Identify site contour and paths of water flow. This will help you plan where to place different plants.
• Test the Soil: Take a few small samples of soil from around the site and do a soil texture test to identify the soil type. Knowing whether the soil is sandy, clay or loam will help with deciding on what plants to choose that will grow there. A soil pH test can also be used to identify if the soil is acidic or alkaline if that is relevant.
• Identify Local Flora: Observe what native plants are already growing in the area. These species are likely well-adapted to the conditions and can provide clues about what other plants with similar growing requirements will thrive there.

2. Use and Value Renewable Resources

Principle: Choose native and drought-tolerant plants that require minimal input once established.

In permaculture, the emphasis is on utilizing resources that are abundant and renewable, reducing dependency on external inputs. This means selecting plants that are native to the area or well-adapted to the local climate, which will require less water, fertilizer, and overall maintenance. Drought-tolerant plants are particularly valuable in urban guerilla gardening, where consistent watering might not be feasible. Additionally, consider using natural materials such as locally sourced mulch, compost, and organic matter to build and maintain soil health. This approach not only reduces waste but also ensures that the garden is resilient and capable of thriving with minimal human intervention.

Practical Tips:

• Select Native Plants: Choose plants that are native to your region, as they are adapted to the local climate and soil. These plants typically need less water and are more resistant to pests.
• Harvest Rainwater: Set up simple systems to collect rainwater, such as placing buckets or barrels under downspouts. Use this water to irrigate your garden during dry spells. Additionally, consider digging swales—shallow, level ditches, also known as contour trenches, that follow the contour of the land—to capture and direct rainwater flow to areas where plants are planted. Swales help slow down runoff, allowing the water to infiltrate the soil and nourish the plants. Berms, raised mounds of soil placed alongside swales, can further direct water flow to specific parts of the garden, ensuring that rainwater is effectively utilized.
• Utilize Organic Mulch: Apply a layer of organic mulch, like wood chips or straw, around your plants to conserve moisture, suppress weeds, and improve soil fertility.

3. Produce No Waste

Principle: Use organic mulch and compost to build soil health naturally.

Permaculture promotes a closed-loop system where waste is minimized, and resources are reused or recycled back into the ecosystem. In guerilla gardening, this principle can be applied by using organic mulch, compost, and other natural materials to build and maintain soil fertility. For example, kitchen scraps, fallen leaves, garden trimmings, and spent coffee grounds collected from local coffee shops can be composted and used to enrich the soil, improving its structure and nutrient content. Additionally, practices like mulching help retain moisture, suppress weeds, and prevent soil erosion, all of which contribute to a healthier garden ecosystem. By producing no waste, you contribute to a sustainable cycle that supports long-term food production and environmental health.

Practical Tips:

• Compost Kitchen Scraps: Collect vegetable peels, coffee grounds, and other organic kitchen waste to create compost that can enrich your garden’s soil. Local cafes can vbbe an excellent source of spent coffee grounds, and also vegetable kitchen scraps. Consider constructing in-ground worm farms from recycled materials to discretely compost onsite and improve the soil.
• Recycle Garden Waste: Use fallen leaves, grass clippings, and pruned branches that are available onsite as mulch or compost material.
• Practice Sheet Mulching: Lay down cardboard or newspaper covered with mulch to smother weeds and improve soil over time, turning waste materials into valuable resources.

4. Design for Self-Regulation

Principle: Plant species that complement each other and form mutually beneficial relationships, reducing the need for human intervention.

Self-regulation in permaculture involves creating systems where plants and other elements support each other, reducing the need for external inputs or human intervention. This can be achieved by selecting a diverse mix of plant species that complement one another in terms of growth habits, nutrient needs, and pest resistance. For instance, companion planting—where certain plants are grown together for mutual benefit—can help control pests naturally and improve soil fertility. Examples include planting nitrogen-fixing legumes alongside heavy feeders like tomatoes, or using marigolds to repel harmful insects. By designing for self-regulation, you create a garden that is more resilient, requires less maintenance, and can continue to thrive even in challenging urban environments.

Practical Tips:

• Companion Planting: Pair plants that benefit each other, such as planting basil with tomatoes to repel pests or growing beans with corn to naturally fix nitrogen in the soil. For more information, see article – What Is Companion Planting And How Does It Work?
• Create Plant Guilds: Design small plant communities where different species support each other, like a mix of fruit trees, shrubs, ground covers, and herbs that mimic a natural ecosystem.
• Encourage Biodiversity: Plant a variety of species to attract beneficial insects, improve pollination, and reduce the risk of pests and diseases taking over your garden.

These permaculture principles not only guide the practical aspects of guerilla gardening but also align with the broader goal of sustainable food production. By working in harmony with natural processes, guerilla gardeners can create productive, resilient spaces that contribute to food security, community empowerment, and environmental restoration in urban areas.

How to Select the Right Location for Guerilla Gardening

The first and most important step in guerilla gardening is finding a suitable location. Choosing the right spot can significantly affect the success of your garden, especially when working in challenging urban environments. A thorough understanding of the landscape is essential to ensure that your garden will thrive with minimal intervention.

Here’s how to read the landscape and assess various environmental factors to select the best location for your guerilla gardening project:

1. Site Visibility

When selecting a location, consider the visibility of the site. High-traffic areas might bring attention to your garden, which can be both beneficial and risky. A well-tended garden in a visible spot can inspire others and gain community support, but it also risks being removed by authorities. Less conspicuous locations, such as behind buildings or in less frequented areas, are better for long-term projects.

Practical Tips:

• Blend with Surroundings: Choose locations where your garden can blend with the existing landscape. For example, plant in areas that already have some greenery to make the garden less noticeable.

2. Soil Health

The health of the soil is critical to the success of your garden. Plants have a much better chance of survival, and are much more resilient to adverse conditions, when the soil is healthy. Spending the extra time on soil preparation is always worth it for any type of gardening, and is even more critical in challenging environments where plants will not receive regular attention.

Urban soils often suffer from compaction, contamination, or nutrient depletion. If soil contamination is suspected, consider using raised beds, but if the soil is safe, then adding organic matter can improve soil quality.

Practical Tips:

• Assess Soil Structure: Dig a small hole to observe the soil structure. Sandy soils drain quickly and may need more organic matter, while clay soils retain moisture but may require aeration to avoid waterlogging. For more information on soil tests see article – Three Simple Soil Composition Tests To Determine What Type Of Soil You Have
• Amend Soil Structure: Improve sandy or clay soils by digging in organic matter, such as compost, fallen leaves gathered from the local area, or spent coffee grounds collected from local coffee shops. Be patient, allow the organic matter time to break down before planting the site. Good soil preparation before planting can make the difference between success and failure in any garden. For more information on soil tests see article – Effective Soil Amendment Methods to Fix Drainage Issues in Sandy and Clay Soils

3. Sunlight and Water Access

Sunlight and water are essential for plant growth. Observe and analyze the site to ensure the site receives adequate sunlight and has a water source nearby or receives sufficient rainfall. However, choose plants that are well-suited to the natural conditions to minimize the need for irrigation.

Practical Tips:

• Observe Sun Patterns: Spend time observing how sunlight moves across the site throughout the day and across different seasons. Note which areas receive full sun, partial shade, or full shade, and how these patterns change from winter to summer, as the sun angle changes from a low to a high position in the sky in midsummer. Are there evergreen trees nearby that screen the sun year round, or deciduous trees that allow the sun through in winter? Sun exposure can greatly impact plant health; for example, sun-loving plants may fail in shaded areas, while shade-tolerant plants might thrive in less sunny spots.
• Identify Moist Areas: Look for signs of moisture retention in the landscape, such as areas where the grass is taller and greener. These spots are likely to stay moist longer after rainfall, making them ideal for plants that need more water.
• Follow Water Flow: After a rain, observe how water flows across the site. Identify the slope of the site, natural drainage paths and low-lying areas where water collects. These areas can be ideal for planting species that prefer wetter conditions, while higher, well-drained areas may suit drought-tolerant plants.
• Consider Water Access: If the site is far from a reliable water source, prioritize plants that are drought-resistant or consider installing a simple rainwater harvesting system. This could involve:
  • Digging swales (contour trenches) which are dug along the contour lines of a slope, following the natural elevation contours to slow down water flow and promote infiltration. They are usually level or have a slight gradient to ensure even distribution of water.
  • Constructing V-catchment trenches (inverted V-swales) which are specific water-harvesting structures designed to direct runoff to a central planting area, usually at the apex of the V, where water collects and infiltrates into the soil to nourish a tree or other plant needing consistent water access. They are particularly useful in arid or semi-arid regions where maximizing water efficiency is critical.
  • Placing barrels or containers to collect runoff from nearby structures on more established reclaimed sites.

4. Wind Exposure

Wind can significantly affect plant growth, especially in exposed areas. Understanding wind patterns in your chosen location can help you protect your plants and ensure their success.

Practical Tips:

• Identify Wind Patterns: Observe the landscape to understand how wind moves through the area. Look for signs like bent trees, worn patches of ground, or areas where debris accumulates. Knowing the direction and strength of prevailing winds will help you decide where to plant wind-sensitive species.
• Locate Sheltered Areas: Protected areas, such as spots behind buildings, walls, or large shrubs, can offer a microclimate that shields plants from strong winds. These areas are ideal for delicate plants or those that require a stable environment.
• Consider Windbreaks: If the area is exposed to strong winds, consider planting a natural windbreak using sturdy, fast-growing plants such as hedges, bamboo or other resilient plants. This can help protect more vulnerable plants by reducing wind speed and buffering the impact.

5. Additional Factors to Consider

Besides the primary considerations, other factors can influence the success of your guerilla gardening project. These include the presence of pollinators, proximity to the community, and seasonal changes in the environment.

Practical Tips:

• Access to Pollinators: Choose locations near existing gardens, parks, or natural areas where pollinators like bees and butterflies are already active. Pollinators are essential for fruit and seed production in many plants, so their presence will enhance the success of your garden.
• Proximity to Community: Planting near a community or in a visible yet protected spot can engage local residents and create a sense of shared ownership. Involving the community can help with garden maintenance and protection. If local residents come to enquire about your activities, remember to be friendly and polite to them, and explain the ecological and community benefits of what you are doing there, and invite them to help maintain or care for the garden, explaining how it belongs to the community. It’s natural that people may be wary of strangers and be concerned that they may have malicious intentions.
• Seasonal Changes: Consider how the site will change throughout the year. In winter, areas that are shaded by buildings may receive more sunlight when the leaves fall off trees. In summer, the same areas might be heavily shaded. Adjust your planting strategy to account for these seasonal variations.

By thoroughly assessing the landscape and understanding the natural conditions of your chosen site, you can select the best location for your guerilla gardening efforts. This careful planning will ensure that your garden is not only sustainable and low-maintenance but also well-adapted to its environment, increasing the likelihood of long-term success.

Soil Contamination Awareness in Guerilla Gardening

Soil contamination is an important consideration in guerilla gardening, especially in urban or roadside locations. The issue with testing for contaminants is that unlike basic soil testing for nutrients and pH levels, which you can do with a home test kit, testing for contamination typically requires a laboratory service and can be costly. Some local or state governments may offer free soil contamination tests, so this is worth checking into. Contamination is a particular concern in areas near roads, as these sites can be polluted by vehicular emissions, such as diesel fuel and heavy metals.

One significant historical source of soil contamination is lead, which was commonly used as an anti-knock agent in gasoline (petrol) to boost octane levels before it was banned. In the United States, leaded gasoline was phased out starting in the 1970s and was completely banned by 1996. However, the legacy of this contamination remains, particularly in soils near older roads and highways where vehicles using leaded gasoline were once prevalent.

Heavy Metal and Hydrocarbon Contamination on Industrial Sites

In addition to contamination from vehicular pollution, old industrial sites can harbor a variety of contaminants, particularly heavy metals and persistent hydrocarbons. These sites, often referred to as “brownfields,” may have been used for manufacturing, chemical processing, or waste disposal, leading to a legacy of soil contamination.

1. Heavy Metals

Common heavy metals found in contaminated soils on industrial sites include lead, cadmium, mercury, and arsenic. These metals are of significant concern because they can persist in the soil for decades due to their non-biodegradable nature. Unlike organic pollutants that may degrade over time, heavy metals do not break down and can remain in the soil indefinitely unless removed or remediated. This persistence makes them a long-term environmental hazard. When present in contaminated soils, these metals pose health risks if they are absorbed by plants, particularly those intended for human consumption, as they can enter the food chain and cause various health problems, including neurological and developmental issues, kidney damage, and cancer.

2. Persistent Hydrocarbons

Industrial sites are also commonly contaminated with Polycyclic Aromatic Hydrocarbons (PAHs) and Petroleum Hydrocarbons (PHCs).

Polycyclic Aromatic Hydrocarbons (PAHs) are a group of organic compounds consisting of multiple aromatic rings (stable, cyclic structures made up of carbon and hydrogen atoms, typically arranged in a flat ring) that are known for their persistence in the environment, especially in soils. These compounds are often found in areas contaminated by the processing and burning of fossil fuels.

Petroleum Hydrocarbons (PHCs), are a broad class of organic compounds derived from crude oil, consisting mainly of alkanes, alkenes, and aromatic hydrocarbons. The structure of PHCs can vary significantly, ranging from simple short-chain molecules to complex long-chain compounds. They are resistant to degradation and can remain in the soil for many years, often ranging from a few decades to over a century, depending on factors such as the specific type of hydrocarbon, environmental conditions, and the presence of microbial activity that might break them down​

Petroleum Hydrocarbons (PHCs) are a diverse group of organic (carbon containing) compounds that vary widely in their structure and environmental impact. They include both saturated and unsaturated hydrocarbons, each with distinct characteristics that contribute to their stability and persistence in the environment.

• Alkanes: These are saturated hydrocarbons with single bonds between carbon atoms. They can be either straight-chain (linear) or branched. The single bonds (C-C and C-H) in alkanes contribute to their stability, making them less reactive but persistent in the environment.
• Alkenes: These are unsaturated hydrocarbons that contain at least one double bond (C=C) between carbon atoms. While alkenes are more reactive than alkanes due to the presence of the double bond, many are still relatively stable and can persist in the environment.

The stability and persistence of PHCs in the environment are largely due to their hydrophobic (water repellent) nature and the strength of the carbon-hydrogen and carbon-carbon bonds. Long-chain hydrocarbons, in particular, are less volatile and more resistant to degradation, which contributes to their persistence in soils and sediments​

Both PAHs and PHCs are harmful to plant life and pose serious health risks to humans, including carcinogenic effects, if they contaminate food crops.

Given these risks, it’s essential for anyone considering guerilla gardening on an old industrial site to be aware of the potential contaminants. Soil testing for heavy metals and hydrocarbons, although costly, is a way of ensuring the safety of any gardening efforts on such sites, otherwise they’re best avoided. If contamination is confirmed, using raised beds with clean soil or creating new soil through composting can reduce exposure to these harmful substances. Understanding the history of the site and the specific contaminants present is important in making informed decisions to protect both your health and the environment.

Choosing Plants for Guerilla Gardening

In guerilla gardening, plant selection is crucial for success. Choose hardy, resilient species that can thrive in less-than-ideal conditions. Permaculture emphasizes the use of native plants, which are already adapted to the local climate and require less maintenance. Consider the following types of plants:

• Perennials: These plants come back year after year, reducing the need for replanting. Examples include herbs like thyme and rosemary, or fruiting plants like strawberries. Perennial vegetables include perennial beans such as Lima “Christmas’ and Scarlet Runner beans, perennial onions such as Walking Onions (Egyptian Onions) and Clumping Onions.
• Nitrogen Fixers: Leguminous plants like clover or lupine can enrich the soil by fixing atmospheric nitrogen, providing a natural fertilizer for other plants and themselves.
• Ground Covers: Low-growing plants like creeping thyme or white clover can suppress weeds, retain moisture, and protect the soil.
• Pollinator Attractors: Plants like lavender, borage, calendulas and marigolds attract bees and other beneficial insects, promoting pollination and biodiversity.

Techniques for Covert Guerilla Gardening

Guerilla gardening often requires a careful balance between visibility and discretion. The goal is to create thriving green spaces while avoiding detection or interference. Here are some techniques to help you garden stealthily and effectively:

1. Planting in the Evening or Early Morning

Why It Works: Planting during these times reduces the likelihood of being seen by passersby, officials, or anyone who might question your activities. In the low light of dawn or dusk, you’re less conspicuous, and fewer people are around.

Practical Tips:

• Plan Your Route: Before heading out, map out your route to the site and identify any potential obstacles, such as security cameras or frequent pedestrian traffic.
• Use Quiet Tools: Opt for hand tools instead of noisy ones to minimize the sound of your activities. A small trowel, hand rake, or pruning shears can be effective and quiet, and carried in a bag discretely if going unnoticed.
• Work Quickly but Carefully: Have your tools and plants ready to go so you can work efficiently. Pre-dig any holes or prepare planting spots if possible, so your time on-site is minimal.

2. Blending In in Public Places

Why It Works: Looking like you belong in the space can help you avoid suspicion. Many people won’t think twice about someone who appears to be a contractor or maintenance worker planting a public space.

When engaging in guerilla gardening in visible locations, blending in with your surroundings can be a crucial strategy for avoiding unwanted attention. One effective way to do this is by dressing the part—wearing typical gardening attire, such as gloves, a hat, and even a high-visibility vest or jacket. Many local governments and municipalities hire contractors to maintain public spaces, and if you look like one of these workers, people are far less likely to question your presence or activities. Carrying common gardening tools, such as a trowel or a watering can, further reinforces the impression that you are simply performing routine maintenance. By adopting this simple disguise, you can work on your guerilla garden openly and confidently, blending into the urban landscape as if you were part of an official project.

Practical Tips:

• Dress the Part: Wear typical gardening attire, such as work gloves, a sun hat, and sturdy boots. A high-visibility vest can be particularly effective, as it’s commonly worn by city workers and contractors.
• Carry Official-Looking Tools: In addition to your gardening tools, carry items like a clipboard or a small bucket. These props make you look like you’re conducting an inspection or routine maintenance.
• Move with Confidence: Act as though you are supposed to be there. People are less likely to question someone who looks and acts like they’re performing an official task.

3. Using Seed Bombs

Why It Works: Seed bombs are a simple and effective way to allow you to plant in hard-to-reach or high-traffic areas without drawing attention. They are an efficient way to introduce plants to areas where direct planting might be too conspicuous.

Practical Tips:

Made from a mix of native or drought-tolerant seeds, compost, and clay, they protect seeds until they can germinate. To make seed bombs, combine 5 parts clay with 1 part compost, add water until the mixture has a dough-like consistency, then mix in the seeds. Shape the mixture into small balls and let them dry for 24-48 hours.

To use, toss seed bombs into areas that need greenery, such as empty lots or roadside verges. For best results, deploy them just before or during the rainy season, as the moisture helps the clay break down, allowing the seeds to germinate.

• Make Seed Bombs at Home: Seed bombs are made from a mix of native or drought-tolerant seeds, compost, and clay, designed to protect seeds until they can germinate. The clay helps shield the seeds from birds and environmental elements, while the compost provides essential nutrients for growth. To make seed bombs, combine 5 parts clay with 1 part compost, add water until the mixture reaches a dough-like consistency, and then mix in the seeds. Shape the mixture into small balls and let them dry for 24-48 hours before use.
• Select Suitable Locations: Toss seed bombs into areas that are difficult to access or have been neglected, such as roadside verges, abandoned lots, or cracks in sidewalks. These sites often hold untapped potential for growth, and the seed bombs will begin to sprout once they receive adequate rainfall.
• Timing Matters: Disperse seed bombs before a rainstorm or in the early morning when the ground is moist. This increases the chances of the seeds germinating and taking root.

4. Set-and-Forget Guerilla Gardening: Planting Nut Trees

One effective guerilla gardening technique is the “set-and-forget” method, where you discreetly plant nut tree seeds in suitable locations and leave them to grow naturally over time. Nut trees are particularly well-suited for this approach because they resemble regular street trees and can take many years to mature and begin producing nuts. By the time they start bearing fruit, they will have already grown to a significant size. This method not only contributes to urban greening but also provides a potential future food source, all while blending seamlessly into the landscape.

Source viable nuts for planting by collecting them from existing trees, as store-bought edible nuts are typically processed (e.g., roasted or shelled), which destroys their ability to germinate, and raw, unprocessed nuts such as walnuts or hazelnuts that are still in their shells might germinate, but the success rate is usually low.

Suitable Nut Trees for Seed Planting:

1. Black Walnut (Juglans nigra): Suitable for USDA zones 4-9, black walnuts are hardy and can thrive in cooler climates. They grow into large trees and are valued for both their nuts and timber.
2. Chestnuts (Castanea species): Varieties like the American chestnut (zones 4-8) and Japanese chestnut (zones 4-8) are good options. These trees produce delicious nuts and can grow in a range of soil conditions.
3. Hazelnuts (Corylus species): Both American hazelnuts and European hazelnuts are hardy in zones 4-8. Hazelnut shrubs are smaller and more adaptable, making them ideal for urban environments.
4. Hickory (Carya ovata): Hickories, particularly the shagbark hickory, are suitable for zones 4-9. They are slow-growing but produce sweet, edible nuts and have a long lifespan.
5. Pecans (Carya illinoinensis): Pecans thrive in warmer climates, particularly in zones 5-9. They require hot summers to produce nuts, making them ideal for southern regions.
6. Macadamia (Macadamia integrifolia and Macadamia tetraphylla): Macadamia trees are an excellent choice for subtropical to tropical regions, particularly in Australian climates such as Queensland and northern New South Wales (USDA zones 9-11). These trees are native to Australia and thrive in warm, humid environments. While they can take 7-10 years to produce nuts, macadamias are well-suited to these climates and can blend seamlessly into the landscape, making them a viable option for long-term guerilla gardening projects​.

These nut trees can grow from seeds, but patience is required as they may take years to bear fruit. Choose species that are well-suited to your local climate to ensure the best chance of success.

Remember, this simply is what squirrels do, and they provide a crucial ecological service by planting a large number of nut trees. Through their behavior of burying nuts as a food reserve, squirrels unintentionally plant seeds that often germinate into new trees. This natural seed dispersal and planting process supports forest regeneration, promotes biodiversity, and helps maintain healthy ecosystems. By spreading nuts over large areas and burying them at optimal depths for germination, squirrels play a vital role in the propagation and sustainability of nut tree species.

5. Camouflaging Your Work

Why It Works: Making your gardening efforts blend seamlessly with the surroundings helps avoid detection and ensures your plants remain undisturbed as they establish themselves.

Practical Tips:

• Use Natural Mulch: After planting, cover the disturbed soil with natural materials like wood chips, leaves, or rocks. This not only hides your work but also helps retain moisture and prevent erosion.
• Mimic the Surroundings: Observe the natural materials already present in the area and use similar items to camouflage your garden. Collect materials form the surrounding area t blend in better. For example, if the site is rocky, use local stones to cover and protect newly planted seeds or seedlings.
• Avoid Straight Lines: Nature doesn’t grow in straight lines, so plant your seeds and seedlings in a more organic, scattered pattern to mimic natural growth and make your work less noticeable, and so it doesn’t look like an intentional planting.
• Plant Amongst Existing Trees and Plants: The addition of a few new young trees or plants spread out amongst many others are difficult to identify as they blend in. This blended biodiversity is a form of visual camouflage that also stops pests from finding their preferred host plants amongst non-host plants in gardens and in nature.

6. Gradual Implementation

Why It Works: Slowly adding plants over time mimics the process of natural succession, the gradual appearance of plants over times, and can make your garden appear more like a naturally occurring ecosystem that is growing on its own, rather than a sudden, deliberate intervention, reducing the likelihood of it being removed or damaged.

Practical Tips:

• Start Small: Begin with a few hardy plants or seed bombs that can survive with minimal care. Observe how they fare over time and gradually expand the garden as they establish themselves.
• Introduce Diversity Gradually: Add different plant species in phases. Start with foundational plants that are resilient and can improve the soil, and can provide a protective microclimate for other plants, then gradually introduce more diverse species that complement each other.
• Monitor Progress: Regularly visit the site to check on your plants’ progress and make adjustments as needed. Add new plants subtly over time to avoid drawing attention to the site.

By using these covert gardening techniques, you can successfully create and maintain guerilla gardens in urban spaces while minimizing the risk of interference. These methods allow you to contribute to urban greening efforts in a way that is both effective and discreet.

Maintaining Your Guerilla Garden

Once your garden is established, it’s important to maintain it discreetly. Regular visits to water, weed, and harvest can help ensure the success of your plants. However, avoid drawing unnecessary attention to your activities. Consider these maintenance tips:

• Watering Wisely: Water your garden during early mornings or late evenings to reduce evaporation and avoid detection. Water can be carried discretely in recycled plastic bottles by a few people and poured around plants if necessary. Use techniques like mulching to retain moisture and reduce the frequency of watering.
• Mulching and Composting: Apply a layer of mulch to suppress weeds and retain soil moisture. If possible, add compost periodically to replenish nutrients. Mulch with plant materials found on site, such as fallen leaves, or cut grass without seed heads and lay it down.
• Harvesting: Pick fruits, vegetables, and herbs as they ripen to avoid waste and encourage continued production. Share the bounty with others to build community support.
• Pruning Herbs: Regular, moderate pruning encourages bushier growth and can extend the life of the plant, making your herb garden more productive over time​. When harvesting herbs, it’s generally safe to prune off up to one-third of the plant’s growth at a time. Leave enough foliage for the plant to continue photosynthesizing and regenerating.to allows the plant to recover and continue growing healthily. For woody herbs like rosemary, thyme, or sage, it’s important to be more cautious. These herbs can be pruned back by about one-third as well, but it’s crucial not to cut into old wood, as these parts of the plant may not regenerate as well.

Plant First, Ask Permission Later: The Guerilla Gardener’s Mantra

In the ethos of guerilla gardening, the phrase “plant first, ask permission later” encapsulates the proactive and often rebellious spirit that drives this movement. This approach is grounded in the belief that immediate action is sometimes necessary to reclaim and transform neglected urban spaces into vibrant green areas. Instead of navigating the often slow and bureaucratic processes to gain permission, guerilla gardeners take the initiative to plant first, knowing that the positive outcomes of their work can serve as their best defense.

This strategy is especially effective in areas where official channels are unresponsive or where community needs for green space and food production are urgent. The visible impact of a flourishing garden—whether it’s a flower bed on a barren lot or a vegetable patch in a food desert—often garners public support, making it difficult for authorities to oppose or dismantle the project. In many cases, the success of these gardens can even lead to formal recognition or protection, turning a once-unauthorized garden into a cherished community resource.

However, this approach also comes with risks. Guerilla gardeners may face fines, legal action, or the removal of their work. Some local government authorities can be quite vindictive, despite claiming to have a commitment to sustainability, food security, the community and environmental matters. Some authorities ‘talk the talk but don’t walk the walk’, their words don’t match their actions. Thus, it’s crucial to understand the local context and community sentiment before proceeding. While “plant first, ask permission later” can be a powerful tactic, it should be employed thoughtfully, with an awareness of both the potential benefits and consequences.

Legal and Ethical Considerations

While guerilla gardening is often seen as a positive act, it’s important to consider the legal and ethical implications. Use common sense, don’t trespass onto private property or plant in areas where it is expressly prohibited, as this can lead to legal consequences. Always weigh the potential benefits against the risks, and consider seeking permission from landowners when possible. Some may be sympathetic to the cause if you take time to explain, and may even offer to assist.

Additionally, be mindful of the ecological impact of your gardening efforts. Avoid introducing invasive species or plants that could disrupt the local ecosystem. Instead, focus on enhancing biodiversity and creating habitats that support native wildlife.
