Yes! Houseplants feel the cold too.
When the temperatures dip and the chilly air makes you want to wrap up in a cosy blanket, your house plants might be feeling the same need for a little extra TLC. Cold weather poses unique challenges for your indoor jungle, but don’t panic; with a few tips and tricks, you can keep your leafy companions thriving until spring comes around.
Why Do Houseplants Suffer in the Cold?
First, let’s uncover why cold weather can be such a drag for your indoor plants. Most houseplants originate from tropical climates like the Snake Plant or ZZ Plant, where temperatures stay consistently warm. When the temperature drops, a houseplant’s growth slows down, and it can struggle to absorb water and nutrients. Too much cold can damage leaves, stems, and roots, leading to wilting, browning, or even plant death.
Signs your houseplant is too cold:
-
Leaves may turn brown, black, or mushy, especially at the tips
-
Growth slows or halts altogether
-
Your plant might droop or look generally unwell despite your care
On top of cold stress, winter also brings lower humidity levels, the dry air from heaters can zap moisture from the air and, consequently, your plant’s leaves.
Signs your plant is too dry:
-
Crispy or curling leaves
-
Increased leaf drop
-
Soil that seems to dry out much faster than usual
But don’t worry! Your houseplants don’t have to suffer through the season.
Here are some simple steps to winter-proof your plant family.
1. Find their sweet spot
Plants are like Goldilocks when it comes to temperature: they don’t want it too hot or too cold. Aim to keep the room between 18°C and 24°C during the day and no cooler than 10°C at night. Keep an eye out for drafts from windows or doors, an icy breeze can shock your plants!
Pro Tip: Use a draft stopper or weatherstripping to seal leaky windows and doors. Not only will this protect your plants, but it’ll also help your heating bill.
2. Location, location, location
During winter, light becomes a precious commodity. Shorter days and weaker sunlight mean your plants might not be getting their daily dose of rays. Move them closer to a south- or west-facing window for maximum light exposure. Just be sure to avoid touching cold glass, which can lower the temperature near the leaves.
Pro Tip: Rotate your plants every week to ensure even light exposure and prevent them from growing lopsided.
3. Cut back on watering
With less sunlight and cooler temperatures, your plants’ growth slows down, meaning they don’t need as much water as they do in summer. Overwatering during winter is one of the easiest ways to harm your plants, as soggy soil can lead to root rot.
Stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it’s still damp, hold off for a few more days.
Pro Tip: Use room-temperature water to avoid shocking the roots.
4. Increase humidity
Indoor house plants love humidity, and the winter air can be as dry as a desert. To keep your plants’ leaves lush and hydrated:
-
Group plants together: They’ll create a mini, humid microclimate
-
Use a humidifier: Your house plants (and your skin) will thank you
-
Misting: Lightly mist your plants, but don’t go overboard, as excess moisture can lead to fungal issues
-
Pebble trays: Place your plant pot on a tray filled with water and pebbles, ensuring the bottom of the pot doesn’t touch the water directly.
5. Dust those leaves
Dust can accumulate on leaves, blocking precious sunlight. Grab a damp cloth and gently wipe down the foliage. This also gives you a chance to inspect your plant for any pests or other issues.
Pro Tip: Be gentle! Delicate leaves can tear if you’re too rough.
6. Hold off on fertiliser
Winter is not the time to push for new growth. Most houseplants go into a sort of dormancy during colder months, so they don’t need extra nutrients. Save the fertilising for spring and summer when growth picks up again.
7. Repot with caution
Unless your plant is absolutely bursting out of its pot or showing signs of root rot, hold off on repotting until the warmer months. Disturbing the roots during winter can add unnecessary stress.
8. Check in on your plant pals
Sometimes, plants just need a little extra companionship. Check in on them regularly to adjust their care as needed. If you spot any signs of distress, like browning leaves or drooping stems, tweak their environment or care routine until they’re back to their cheerful selves.
A little extra warmth
If you live in an especially cold area or have indoor plants in less insulated spots like basements, consider using a space heater (safely) or adding thermal curtains to keep the chill out. For the real plant enthusiasts out there, heating mats designed for seedlings can provide a gentle warmth to keep roots cosy.
Protecting your houseplants in cold weather doesn’t have to be a chore. By providing the right environment, watering less, boosting humidity, and ensuring plenty of light, your indoor jungle can ride out the winter like a champ. Remember, each plant is unique, so listen to their needs and adjust your care as necessary.
Before you know it, spring will arrive, and your plants will be ready to burst with fresh growth, as happy and healthy as ever. So, snuggle up with a cup of tea, give your plants a loving glance, and enjoy the cosy season together.
