Indoor plants sometimes appear to decline during certain times of year—dropping leaves, slowing growth, or developing a withered appearance. But these changes don’t always signal poor health or death. In many cases, the plant is simply going dormant, a natural physiological state that allows it to conserve energy and survive unfavorable conditions.

Understanding the difference between dormancy and decline is crucial to appropriate plant care. This article explores the botany of dormancy, identifies which houseplants are prone to it, distinguishes it from symptoms of disease or death, and explains how to care for plants correctly during dormant periods.

What Is Dormancy in Plants?

Dormancy is a period of suspended growth and reduced metabolic activity that helps perennial plants survive seasonal environmental stress, particularly cold or drought. It is a genetically programmed response regulated by internal hormones—especially abscisic acid—and triggered by environmental cues such as photoperiod (day length), temperature, or soil moisture. During dormancy, plants redirect resources away from new growth and toward survival processes such as root maintenance or carbohydrate storage.

Dormancy differs fundamentally from senescence, which is the programmed degradation of tissues (such as leaves) due to age or resource reallocation. While senescence may occur during dormancy (e.g. leaf drop in deciduous species), dormancy itself is reversible, whereas plant death is not.

In indoor plants, dormancy may be less pronounced due to stable indoor temperatures, but many species retain their seasonal rhythms regardless of indoor conditions.

Which Houseplants Naturally Go Dormant?

Most common indoor foliage plants are tropical evergreen species and do not undergo true dormancy under indoor conditions. However, some houseplants—especially geophytes (bulb- or tuber-forming plants), succulents, and certain temperate perennials—enter dormancy as part of their natural cycle. Examples include:

These responses are not signs of ill health—they are seasonal adaptations. Conversely, species such as pothos, philodendron, and peace lily are evergreen in their native habitat and typically grow slowly year-round rather than going dormant.

Signs a Plant Is Dormant—Not Dying

Dormant plants may look lifeless, but they remain biologically active beneath the surface. Key indicators of dormancy include:

By contrast, a dying plant may exhibit symptoms such as:

If in doubt, check root and stem health. Healthy root systems should be firm and white or tan—not brown and mushy.

When a plant is dormant, its needs this change. Trying to stimulate growth with water or fertilizer during dormancy can do more harm than good.

Appropriate care of dormant houseplants includes:

For bulbous or tuberous plants that lose all top growth (e.g. Caladium), store the dormant tuber in a dry, dark place at a stable temperature until spring, then replant in fresh potting mix.

When to Resume Normal Care

Plants break dormancy when environmental conditions improve—longer daylight hours, warmer temperatures, or more moisture. Signs of reactivation include:

At this stage, gradually resume watering and feeding. Use a diluted, balanced fertilizer to support renewed growth.

Final Thoughts

Recognizing dormancy is essential for successful long-term indoor plant care. It prevents unnecessary interventions and supports each plant’s natural rhythm. While evergreen tropicals may grow slowly year-round, species like Caladium, ZZ Plant, and Alocasia require rest periods to remain healthy. Differentiating dormancy from decline involves observing patterns, inspecting roots, and understanding species-specific cycles. With this knowledge, you can care for your indoor garden more confidently and effectively.
