One of the downsides though to using such deep pots is the large volume of growing medium (potting mix) that it takes to fill them! What are the problems with filling tall potsContinue reading “The Best Ways to Fill Space in Tall Plant Pots That Are Too Deep”
How Much of a Difference Does the Thermal Mass of a Wall Make for Plants and Trees in Winter?
Warm season vegetables and fruit trees are often grown close to brick, stone and concrete walls facing the midday or afternoon sun. This is because these surfaces act as a thermal mass, heating up during the day, and releasing the heat at night as the temperature drops, keeping the air around the plants a bitContinue reading “How Much of a Difference Does the Thermal Mass of a Wall Make for Plants and Trees in Winter?”
What is the Ideal Soil Depth for Wicking Beds?
Wicking beds are self-watering raised garden beds, that operate on the principle of sub-irrigation. Water stored in a reservoir located at the bottom wicks water upwards to the soil above, watering the plants from below. When constructing wicking beds, it’s important to understand how they operate, and the needs of the plants that will beContinue reading “What is the Ideal Soil Depth for Wicking Beds?”

Permaculture Plants – Australian Indigo, the Nitrogen Fixing Tree for Small Sites, an Alternative to Tagasaste for Urban Gardens
In permaculture, tagasaste (tree lucerne) is used as a nitrogen-fixing tree on large sites and rural properties, but it can grow around 5-7m tall and equally wide, which is way too large for smaller urban properties. Luckily for Australian permaculture gardeners, we have a much smaller nitrogen-fixing tree available which works much better in small-scaleContinue reading “Permaculture Plants – Australian Indigo, the Nitrogen Fixing Tree for Small Sites, an Alternative to Tagasaste for Urban Gardens”
Permaculture Plants – Tagasaste, the Nitrogen Fixing Tree for Large Sites

A tree that could do almost everything would be incredible, but it doesn’t exist. The next best thing would be a tree that does aContinue reading “Permaculture Plants – Tagasaste, the Nitrogen Fixing Tree for Large Sites”
Should You Tease Out Plant Roots When Transplanting? Garden Mythbusting!
Any gardener who has ever transplanted or repotted plants has seen first-hand how plants that have been grown in pots can sometimes get rootbound, with their roots spiralling or circling around the rootball.
