When the winter chill sets in, it's easy for us to bring out our cozy throw blankets and warm up. But what about our houseplants? It's a known fact that indoor gardens need a touch of extra help to stay thriving, and the temperature is among the most important things to consider.
And this goes for even the best indoor winter plants. So, what's the best temperature for your cultivars to feel comfortable and grow healthily through the end of the year?
Well, I asked the experts and here's what they had to say.
Do Houseplants Feel Cold in the Winter?
Although plants don't technically experience the cold like people or pets do, gardening expert Lindsey Chastain explains that they do react to temperature changes.
"As the temperature cools off, the plants will slow down growth. And in turn, humidity levels tend to drop, so plants can also get drier in colder temperatures," she says. "The trick is balancing between keeping the indoor ambiance while accommodating for slower growth."
When it comes to these common problems in winter houseplants, understanding the ideal temperature is one of the key ways to support your cultivars so that they remain comfortable.
What's the Ideal Temperature for Indoor Gardens in the Winter?
Marina Prokaten, gardening expert at Plantum, warns that your comfortable temperature isn’t always 100% suitable for your home garden. "Most plants thrive best within the temperature range of 16° to 24° C," she says.
"This is a perfect range for the majority of indoor foliage, including caladiums and hostas. Most flowering types like begonias and African violets prefer the same temperatures during the day with a drop to 13° to 16° C at night, which imitates their natural growing conditions."
She tells me that most low-maintenance indoor plants aren't highly sensitive to temperatures and will be happy and healthy within this range.
How to Tell When the Temperature Needs Adjusting
According to Marina, the most common symptoms of the wrong temperature regime are slow growth and poor blooming. "If you notice the leaves on your houseplant curling, dropping, browning, or yellowing, this could also indicate inoptimal temperatures," she notes.
"However, these same symptoms may indicate other problems. So make sure to eliminate other potential problem factors before coming to the conclusion that your plants need higher or lower temperatures."
This is especially important when growing cold-tolerant indoor plants since they aren't as sensitive to winter weather. Or, you can use houseplants for temperature control, too. There are plenty of options, and no reason your collection should suffer the consequences of the cold.
