Winter Dormancy
Winter dormancy is a natural slowdown in growth that most houseplants experience during the shorter, cooler days of late fall and winter. Understanding and respecting this period is essential for keeping plants healthy year-round.
What Does It Mean?
During dormancy, reduced daylight and lower temperatures signal plants to conserve energy. Growth slows or stops entirely, water uptake decreases, and the plant enters a resting phase. This is not a sign of illness but a normal biological rhythm inherited from their native environments, where seasonal changes in rainfall or temperature trigger rest periods even in tropical species.
Why It Matters
Continuing to water and fertilize at summer rates during dormancy is a leading cause of winter root rot and salt buildup. The plant simply cannot use the resources being provided, so excess water sits in the soil and excess nutrients accumulate to toxic levels. Recognizing dormancy helps you adjust care appropriately and avoid unnecessary panic when growth pauses.
How to Apply It
Reduce watering frequency significantly in winter, allowing the soil to dry out more between waterings than you would in summer. Stop fertilizing entirely from late fall through early spring for most houseplants. Keep plants away from cold drafts and heating vents, both of which cause stress, and consider supplementing light with a grow lamp if your home receives very little natural winter light.
Examples
- •A Fiddle Leaf Fig producing no new leaves from November through February, then flushing with growth in spring.
- •Reducing watering of a Snake Plant to once a month during winter when it shows no active growth.
- •Moving a collection of tropicals away from a radiator that creates hot, dry air currents in winter.
