Houseplant Care in Winter: Simple Adjustments That Make a Big Difference

Winter changes everything for houseplants. Learn how to adjust watering, light, and humidity so indoor plants stay healthy all season.

If you saw some of my houseplants right now, you would notice that not all of them look amazing. Some look pretty good. Others look a little tired and worn down. That is completely normal this time of year.

I have been gardening for decades, and after years of growing houseplants through long northeastern winters, I have learned that winter is not about growth. It is about getting plants through a season of lower light, dry indoor air, and slower metabolism. If you can support them until early spring, most houseplants bounce back beautifully once days lengthen and conditions improve.

Indoor plants naturally slow down in winter. Light levels drop, humidity disappears once the heat turns on, and plants use far less water and energy than they do during the growing season. Leaves may yellow or drop, and growth often pauses altogether. That does not mean something is wrong.

Understanding these seasonal shifts makes winter plant care far less stressful. Instead of trying to fix every change, the goal is to make a few simple adjustments that support plants while they rest. If you need a refresher on the basics that apply year round, my houseplant care guide walks through light, watering, and general care in more detail.

Below are the winter specific adjustments I make every year to help my houseplants stay healthy until spring returns.

What Happens to Houseplants in Winter

Winter changes everything about how plants behave indoors.

Days are shorter. Light levels drop. Indoor heat dries the air. Growth slows dramatically, and many plants enter a natural resting phase called dormancy.

During dormancy, foliage growth slows or pauses altogether. Some plants shed leaves. Others simply stop growing. What most people do not realize is that roots often continue working quietly beneath the soil even when the top of the plant looks tired.

This is why winter is not the time to push plants to perform. It is the season to support them gently and avoid mistakes that cause long term damage.

Winter Plant Care Basics: Less Is More

The biggest mistake I see with winter plant care is doing too much. Most houseplants need fewer inputs right now, not more.

Stop Watering on a Weekly Schedule

If there is one habit to break in winter, this is it. Watering on the same day every week is the fastest way to kill houseplants during the colder months. Plants use water much more slowly in winter, and soil stays wet longer because evaporation is reduced.

Instead of watering on a schedule, check the soil weekly and only water when the plant actually needs it.

Succulents, snake plants, ZZ plants, and similar drought tolerant plants may only need water once every few weeks or even less. Many of mine get watered about once a month in winter.

If watering has been a struggle, this guide to watering indoor plants explains how to read soil moisture properly and avoid overwatering.

Keep Plants Away From Drafts and Heat

Winter air movement can be brutal on houseplants. Cold drafts from windows and doors stress foliage and roots. At the same time, hot air from vents, radiators, and fireplaces dries plants out quickly.

Most houseplants prefer steady temperatures between 65 and 75 degrees during the day and no colder than 50 at night.

Plants still need light, so do not pull them away from windows entirely. Just make sure they are not sitting in a cold draft or directly above a heat source.

This is also why I sometimes use faux plants near fireplaces or high heat areas. Some spots are simply not good plant environments, and that is okay.

Light Still Matters in Winter

Light is one of the biggest limiting factors for plants in winter.

South facing windows provide the strongest light. East and west windows offer moderate light. North facing windows are low light.

As winter progresses, you may need to move plants closer to windows or rotate them more often to keep growth even. If a plant looks leggy or pale, insufficient light is often the reason.

This is not about forcing growth. It is about giving plants enough light to maintain health until spring. If you’re not sure about the light conditions in your home, please visit my light conditions guide here.

Add Humidity If Plants Look Crispy

Most houseplants are tropical and prefer higher humidity than our winter homes provide. Dry indoor heat can cause brown leaf edges, crispy tips, and increased leaf drop.

There are a few ways to increase humidity:

• Group plants together to create a microclimate
• Use a humidifier near sensitive plants
• Place shallow trays of water nearby to slowly evaporate

Personally, I rely mostly on grouping plants. A few years ago, I added a humidifier to my sunroom specifically for a Boston fern. It was the first time I managed to keep one alive through winter, and it is still thriving today. That experience completely changed how I approach humidity for certain plants.

Misting can help short term, but consistency matters more than occasional sprays.

Do Not Fertilize Heavily Right Now

Winter is not the time for synthetic or heavy fertilizers. Plants are resting, and pushing growth now often leads to weak foliage or root stress.

That said, there is one exception I strongly recommend. Using a gentle organic liquid fertilizer diluted into your water can be beneficial, especially if you are watering lightly and infrequently. I have been doing this for several years now, adding a mild organic liquid fertilizer every time I water during winter, and my plants have never looked better.

The key is consistency and dilution. Think nourishment, not stimulation.

If you want to use synthetic fertilizers, hold off completely during winter and wait until late February or early March to resume regular feeding as days lengthen and growth resumes.

How to Tell If a Plant Is Still Alive in Winter

Before giving up on a struggling plant, check for signs of life.

Scratch Test

Lightly scratch the bark of a woody stem. If you see green underneath, the plant is alive.

Snap Test

Gently bend a small stem. If it snaps cleanly and is dry inside, that section may be dead. Flexible or moist stems indicate life.

Check the Roots

If you are truly unsure, slide the plant out of its pot and inspect the roots. Healthy roots are firm and light colored. Mushy, dark roots indicate rot.

Many plants that look rough above the soil are perfectly fine below it.

Keep Plants Clean Through Winter

Dust builds up quickly indoors during winter and blocks light from reaching leaves. Wipe leaves with a damp cloth or rinse plants gently in the shower. This improves photosynthesis and helps prevent pest issues.

Clean plants are healthier plants.

How to Revive Plants That Are Struggling

As long as a plant still has green tissue, there is hope.

Remove dead foliage. Adjust watering. Improve light. Correct drainage issues if needed.

I have revived many plants after winter stress, especially after moves or changes in environment. If a plant needs more intervention, this guide to reviving houseplants walks through the process step by step.

Final Thoughts: Winter Is a Holding Season

Winter plant care is about patience, not perfection.

After decades of gardening and many winters growing houseplants through low light, dry air, and long stretches indoors, I have learned that winter is not the season to push plants. It is the season to protect them. Your goal is not lush growth or flawless foliage. Your goal is healthy roots, stable conditions, and avoiding the kinds of mistakes that cause long-term stress.

If you find yourself second-guessing what your plants need, revisit the foundational basics in my houseplant care guide, where I walk through how light, water, and environment work together year round. Winter simply asks us to apply those principles more gently.

Most winter problems come from overwatering or reacting too quickly to cosmetic changes. If watering feels confusing right now, my guide on how to water indoor plants correctly explains how to adjust based on season, soil, and light rather than habit. Light matters just as much, and understanding your indoor light conditions can help you decide whether a plant is truly struggling or simply resting.

And if a plant does start to decline, that does not mean it is a lost cause. I have brought many plants back over the years by slowing down, correcting care, and giving them time. My guide on reviving houseplants walks through how to assess roots, growth, and recovery step by step.

Every spring, I watch tired plants wake up quickly once days lengthen and temperatures stabilize. If your plants look a little worn by late winter, that does not mean you failed. It means they rested.

Keep caring gently. Spring will do the rest.
