Many houseplants behave differently once winter arrives. Growth can slow, watering needs may change, and some plants might drop leaves or look less vigorous than they did during the warmer months.
That doesn’t always mean something is wrong. Many houseplants respond to shorter days, lower light levels, and drier indoor air by slowing their growth. Some plants enter a more defined dormant period, while others simply grow much more slowly until conditions improve.
Knowing what to expect can help you adjust your plant care routine without overcorrecting.
At a Glance: Winter Houseplant Care
During the winter months:
- Expect many plants to grow more slowly.
- Check the soil before watering instead of following a fixed schedule.
- Keep plants where they can receive the light they need.
- Hold back on fertilizer if the plant isn’t actively growing.
- Watch for leaf drop, pests, and signs of overwatering.
- Keep plants away from cold drafts and direct heat sources.
- Resume more active care as new growth returns.
The biggest change is typically just doing a little less.
What Is Plant Dormancy?
Dormancy is a period when a plant reduces its growth and conserves energy in response to seasonal conditions.
True dormancy is especially important for many outdoor perennials, bulbs, shrubs, and trees. Houseplants are a little different. Many common indoor plants come from tropical or subtropical environments and may not become fully dormant indoors. Instead, they often experience slower growth because winter brings shorter days, lower light levels, and changes in temperature and humidity.
For everyday plant care, the practical takeaway is the same: when growth slows, the plant usually needs less water and fertilizer than it does during a more active growing season.
How Can You Tell If a Plant Is Slowing Down for Winter?
A plant going through a normal seasonal slowdown might:
- Produce fewer new leaves
- Grow more slowly than usual
- Drop an occasional older leaf
- Use water more slowly
- Look less full or vibrant than it did during spring and summer
Some leaf yellowing or drop can also happen when plants are moved indoors or experience a significant change in light. Plants that are brought inside may take one to two months to adjust to their new environment.
What you don’t want to do is assume every struggling plant is dormant. Widespread yellowing, mushy stems, severe wilting, pests, or a foul smell from the soil could point to another problem.
Should You Water Houseplants Less in Winter?
Typically, houseplants need less water in the winter, but don’t stop watering or assume every plant should dry out completely. Plants that are growing more slowly generally use water more slowly. This means winter an easy time to overwater if you keep following the same schedule you used during summer.
Instead of watering on a schedule, check the soil with your finger first. If it’s dry, it’s likely time to water. If there’s still moisture a few inches in, check again in another day or two.
The pot should also have good drainage so excess water doesn’t sit around the roots.
Do Houseplants Still Need Light During Winter?
Slower growth doesn’t mean plants can go without light. In fact, shorter winter days can make placement even more important. A plant that did well several feet from a window during summer may benefit from moving closer to a brighter window in winter. Just make sure the new location doesn’t expose it to cold drafts or extreme temperature swings.
If natural light is limited, a grow light can supplement what the plant receives from the window.
Should You Fertilize Dormant Houseplants?
Fertilizer supports active growth, so adding it when a plant isn’t producing new leaves or stems may not provide much benefit. Most indoor plants don’t need fertilizer during winter because of lower light levels, and fertilizer is generally unnecessary when a plant isn’t actively growing.
Once you see new growth returning, you can gradually resume the fertilizing routine recommended for that particular plant.
What About Dry Indoor Air?
Winter heating can make indoor air noticeably drier. If a humidity-loving plant develops dry leaf edges or seems stressed, consider moving it away from heating vents or using a humidifier nearby.
Grouping plants together may help somewhat, but the best plan depends on the species. Cacti and many succulents, for example, generally don’t need the same humidity levels as tropical foliage plants.
When Should You Start Normal Care Again?
As daylight increases and growing conditions improve, you may notice new leaves, shoots, or faster growth. Water will also start disappearing from the soil more quickly. That’s the time to gradually return to more frequent watering and, where appropriate, resume fertilizing.
Pay attention to what the plant is telling you instead of relying on the calendar.
Frequently Asked Questions About Winter Houseplant Care
Do all houseplants go dormant in winter?
No. Some plants enter true dormancy, while many common houseplants simply grow more slowly because winter provides less light and different indoor conditions.
Is yellowing normal during winter?
An occasional yellow leaf can be part of a seasonal adjustment, especially after a plant has been moved or exposed to lower light. Extensive yellowing may also indicate overwatering, pests, root problems, or another issue.
How often should I water houseplants in winter?
There isn’t one rule that works for every plant. Check the soil and consider the plant’s individual moisture needs before watering.
Should I move my plants closer to a window in winter?
It can help if the plant isn’t receiving enough light in its usual spot. Make sure the new location still suits the plant and isn’t too close to cold drafts or heating vents.
Can I fertilize houseplants during winter?
If a plant is actively growing, light fertilizing may still be appropriate depending on the species. If growth has slowed considerably or stopped, fertilizer is usually unnecessary until active growth returns.
Let Your Plants Set the Pace
Winter houseplant care is less about following a strict seasonal checklist and more about noticing how the plant responds to changing conditions.
If growth slows, reduce watering accordingly, keep an eye on light and humidity, and avoid pushing new growth with unnecessary fertilizer. As days lengthen and new growth appears, you can gradually return to the routine that works during the more active growing season.
