Turns out, plants are humidifiers themselves. But you can help them out.
Whether you own a single African violet or your house is a veritable indoor jungle, giving indoor plants the best possible environment—including the right humidity—will help them thrive. But what is the right humidity for houseplants, and how can you provide it?
Fortunately, you don’t need to do a lot. Plants typically don’t need much help in getting the right humidity because they are their own little humidifiers.
“Plants have the uncanny ability to regulate the humidity around them,” says Chris Raimondi, who is president of Raimondi Horticultural Group in Hohokus, N.J., and teaches interior landscaping and plantings at the New York Botanical Garden in the Bronx borough of New York City. “They exude more moisture when it’s dry and less when it’s damp. They will adapt to their surroundings.”
That said, certain plants—like that African violet—need more than the typical room humidity to be their best. Others, like cacti and succulents, need less. But even if you deck out your living room with rainforest ferns, it doesn’t take much to create the right humidity for them to flourish.
How Plants Create Their Own Humidity
Plants add moisture to the air through a process called evapotranspiration. Their roots draw water from the soil; their stalks and stems carry it up into the leaves. Water then evaporates through the pores of the leaves, also known as stomata. The more moisture that’s needed around the plant, the more moisture the plant will emit.
While houseplants do add moisture to the air, baseline humidity levels in their environments can help them really thrive. Typically, that’s when indoor relative humidity is between 40 and 60 percent. The optimal humidity for humans is 30 to 50 percent, according to EnergyStar, so the overlap is in the 40 to 50 percent range.
Have the Right Tools on Hand
If you’re unsure about the humidity of your spaces, invest in a hygrometer, a simple device that measures relative room humidity. You can find one for less than $10; they’re sometimes paired with room thermometers. (If your home humidity isn’t within the optimal range for humans, consider investing in a humidifier or dehumidifier that can address the issue.) Take these steps as well to ensure the best humidity for plant growth.
Learn about your plants. Use an app like PlantNet (free) or NatureID (three-day free trial; $20 yearly) to identify your plant if you’re uncertain and learn about its care and watering schedule.
Use the right pots. Your plants should sit in pots big enough to allow for root growth, with soil loosely packed to promote drainage. The pot should have at least one sizable drainage hole.
Set up an evaporation system. This key step will help add more moisture around your plant than what your watering can provides. Place each pot on a shallow tray or saucer lined with gravel, marbles, pebbles, or clay potting stones; then add water to that shallow container. As the water evaporates around the plant, it adds humidity to the air; it’ll also catch runoff from watering. To prevent root rot, be sure the tray water doesn’t reach the pot’s bottom. “Most of the plants we’re dealing with indoors love humidity, but they don’t like wet feet,’’ Raimondi says.
Buy a mister. In addition to a watering can, a quart-sized hand-mist bottle comes in handy for plants that crave humidity, Raimondi says.
Group Plants by Their Humidity Preference
Because certain types of plants are happier in moist environments while others prefer it rather dry, it makes sense to group together plants that have similar humidity requirements, says Anastasia Akhrameika, a plant expert for the app NatureID. On their own, those birds of a feather will regulate their environment. By placing, say, tropical plants in one spot, Akhrameika explains, “the plants will boost humidity among themselves.”
Here are some basic plant categories, in order of humidity needs.
Cacti and succulents: Jade plants, aloes, and other succulents—in addition to snake plants and cacti—are accustomed to arid environments. While a relative indoor humidity of less than 30 percent may bother your family, these dry-climate plants will be perfectly content. “If you have a hot, dry windowsill, that’s a good choice,” Raimondi says.
Large, leafy plants: Monsteras, peace lily, and other common indoor plants originated in the tropics and prefer higher humidity. But they’ll manage fine in the range that is optimal for humans, Raimondi says. Indeed, Mary Jane Duford, a gardening blogger based in British Columbia’s Okanagan Valley, says her home’s normal humidity range of 40 to 50 percent in winter—aided by a whole-house humidifier—suits both the leafy plants and the humans who live there. “It also seems to benefit our musical instruments and hardwood floors,” she says.
Moisture lovers: Plants like moth orchid and Boston fern-like muggy environments; orchids thrive in rooms with 50 to 80 percent humidity; ferns are most comfortable at the higher end of that range. These plants do well in bathrooms and kitchens, Akhrameika says. Another tactic is to double-pot them: Plant them in terracotta pots, and place those pots inside larger, plastic pots. (Plastic won’t lose moisture as fast as porous terracotta.) In the space between the two pots, place sphagnum moss; you can get it at many garden centers. Keep that moss watered and moist.
Air plants and bromeliads: These obtain moisture from the air and not the soil, so they require humidity as high as 70 percent. You’ll need to regularly mist around them, buy a dedicated humidifier for them, or place them in a greenhouse or terrarium.
If you’re seeking plug-and-play plants that can stand up to a wide range of indoor humidity levels, consider hardy workhorses such as pothos and spider plants. “They’re just wonderfully easy-going,” says Erinn Witz, co-founder of Seedsandspades, a website for home gardeners. “While they would appreciate some supplemental humidity, they’ll still grow happily even without it in most situations.”
