Taking care of orchids during winter starts with understanding that their needs shift dramatically when the days get shorter and the air turns dry.
Orchids enter a slower growth phase in winter, but that doesn’t mean they can be ignored.
If you’ve been wondering how to take care of orchids during winter, the honest answer is that they need a bit more attention to watering, light, and temperature than they do in warmer months.
The good news is that with a few simple adjustments, your orchids can not only survive winter but actually thrive through it.
In this post, we’ll walk through the key steps for winter orchid care, including watering routines, light management, and how to protect them from cold drafts.
Let’s dive in and make sure your orchids stay healthy all season long.
Why Taking Care of Orchids During Winter Requires a Different Approach
Taking care of orchids during winter isn’t about working harder, it’s about working smarter.
Your orchid’s natural habitat changes, and your home’s indoor environment changes along with it.
Heating systems dry out the air, windows let in cold drafts, and daylight hours shrink, all of which stress your plant.
That’s why winter orchid care focuses on counteracting these three big issues: low humidity, reduced light, and temperature swings.
When you understand these challenges, you can easily adjust your routine and keep your orchid happy.
1. Low Humidity Is the Number One Enemy
During winter, indoor air can drop to 20–30% humidity, while orchids naturally prefer 50–70%.
This dry air pulls moisture from the leaves and roots faster than the plant can replace it.
You’ll notice wrinkled leaves or shriveled pseudobulbs, classic signs that your orchid is thirsty for humidity.
To fix this, place a humidity tray filled with water and pebbles under the pot, but make sure the pot isn’t sitting directly in the water.
Alternatively, run a small room humidifier near your plants, especially if you run the heat constantly.
Grouping several orchids together also creates a microclimate with higher moisture levels.
2. Light Levels Drop and Your Orchid Feels It
Winter means fewer daylight hours and weaker sunlight, especially in northern climates.
Most orchids, like Phalaenopsis, need bright, indirect light to photosynthesize properly.
Without enough light, your orchid won’t produce new growth or flower spikes, and it may drop existing buds.
Move your orchid to a south or east-facing window where it can catch the most morning sun.
If that’s not possible, invest in a simple grow light and run it for 10–12 hours a day.
Just be careful not to expose leaves to direct afternoon sun, which can burn them through the cold glass.
3. Temperature Swings Stress Orchids Out
Orchids are tropical plants, and they hate sudden cold drafts or extreme heat blasts from vents.
During winter, taking care of orchids during winter means keeping the temperature steady, ideally between 65–75°F during the day and no lower than 60°F at night.
A slight drop at night, around 10°F, can actually encourage blooming, but don’t let it go too low.
Keep orchids away from doors that open frequently, drafty windows, and heating vents or radiators.
Even a brief chill can cause bud blast, where flowers drop before they open.
How to Take Care of Orchids During Winter: Watering and Feeding
Watering is the trickiest part of winter orchid care because your plant’s water needs decrease.
In summer, you might water every 5–7 days, but in winter, that schedule can stretch to every 10–14 days.
Overwatering is the most common mistake people make, and it leads to root rot, which is often fatal.
The key is to check the potting medium’s moisture level before watering, and never water on a fixed schedule.
1. Water Less Frequently but More Thoroughly
Stick your finger about an inch into the bark or moss, and if it feels dry, it’s time to water.
If it feels damp or cool, wait a few more days.
When you do water, use lukewarm water (not cold) and let it run through the pot until it drains out the bottom.
Then make sure the pot isn’t left sitting in standing water, as that will suffocate the roots.
Water in the morning so the leaves have time to dry before nightfall, which prevents fungal diseases.
2. Skip Fertilizer or Cut It Way Back
Because your orchid grows slowly in winter, it doesn’t need much fertilizer.
Feeding it too much can burn the roots and cause salt buildup in the potting mix.
If you want to take care of orchids during winter properly, fertilize only once a month at half strength.
Use a balanced orchid fertilizer, like 20-20-20, diluted to half the recommended dose.
And if your orchid is actively blooming, stop fertilizing entirely until the flowers fade.
3. Watch for Root Health Signs
Healthy roots are firm and green or silvery, while rotting roots are brown, mushy, and smell bad.
Check the roots regularly by peeking through the clear plastic pot if you have one.
If you see rot, you’ll need to repot your orchid, but only do this in winter if absolutely necessary.
Repotting causes stress, and winter is already a stressful time for your plant.
Instead, just trim away dead roots and adjust your watering routine to prevent further damage.
Winter Orchid Care: What About Dormancy and Bloom Cycles?
Many orchids naturally go through a dormant period during winter, and taking care of orchids during winter includes respecting that rest phase.
Some varieties, like Cattleyas, need a cooler, drier rest to trigger spring blooming.
Others, like Phalaenopsis, don’t go fully dormant but slow down their growth.
Knowing which type you have helps you adjust your care accordingly.
1. Let Some Orchids Rest Completely
Dendrobiums and Cattleyas often need a winter rest with cooler temps and almost no watering.
During this rest, water only enough to keep the pseudobulbs from shriveling too much, maybe once every three weeks.
Move them to a cooler room with bright light, and don’t fertilize at all during this time.
This rest is essential for producing strong new growth and flowers in spring.
2. Keep Blooming Orchids Comfortable
If your Phalaenopsis is actively blooming in winter, don’t move it around a lot.
Sudden changes in light, temperature, or location can make it drop its flowers.
Keep it in a stable spot with consistent light and water it a little more often, but still check the medium first.
You can also stake the flower spike gently if it gets heavy.
3. Stop Repotting Unless It’s an Emergency
Repotting in winter is only recommended if the roots are rotting or the medium has broken down completely.
Otherwise, wait until spring when the orchid is actively growing and can recover faster.
If you must repot, use fresh bark mix and be very gentle with the roots.
Then keep the orchid in a warm, humid spot for a few weeks to help it recover.
Final Tips to Master How to Take Care of Orchids During Winter
Beyond watering and light, there are a few extra things you can do to improve your winter orchid care routine.
First, clean the leaves gently with a damp cloth to remove dust, which blocks light absorption.
Second, check regularly for pests like spider mites and mealybugs, which thrive in dry indoor air.
And third, don’t place orchids near fruit bowls, as ripening fruit releases ethylene gas that can harm flowers.
These small touches make a big difference in keeping your orchid vibrant all winter.
So, How to Take Care of Orchids During Winter?
Taking care of orchids during winter boils down to mimicking their tropical home as closely as possible.
You need to boost humidity, maximize light, stabilize temperatures, and water less frequently but more carefully.
You also need to respect dormancy, cut back on fertilizer, and avoid repotting unless necessary.
By following these steps, you’ll give your orchid the best chance to survive winter and reward you with spectacular blooms in the warmer months.
So don’t stress over winter orchid care, just adjust your routine and watch your plant thrive.
Your orchid is tougher than you think, it just needs a little help from you.
