In addition to even-keeled temperatures, your plants also prefer a bit of humidity in the winter months. "If your skin is feeling dry, imagine how your plants feel," says Danae Horst, founder of L.A.-based plant shop Folia Collective. "Dry winter air and heaters running more means you'll need to add humidity to the rooms you keep plants in, especially if you have tropicals, which many indoor plants are."
There are a few different ways to ensure your home has optimal humidity for your plants. If you don't have a humidifier, Horst recommends humidity trays filled with a shallow layer of water and pebbles that plants can sit atop. Vassilkioti mists the air around her plant pals daily, while Summer Rayne Oakes, a nature lover who lives surrounded by 500 houseplants, uses humidifiers. "I have a BONECO, which you can program the level of humidity," she says. "I personally like to keep it in the 50 to 70 percent range."
