Water dripping from leaf to leaf can also spread pathogens like harmful fungus and bacteria from leaf to leaf. Therefore, you shouldn't mist a plant with a condition like powdery mildew or a bacterial infection. Generally, you want to avoid misting so much that water is dripping off the leaves.
It is possible to overmist? As they say, too much of anything is still too much. Repeatedly dousing your plants with moisture is no exception, so Resta says be careful not to overdo it. "You want to be cautious about how much water may be gathering on your leaves' surface," she notes.
Consider misting your plants once or twice a week during the cooler months because the air is dry, and require less frequent misting in warmer months when humidity levels are higher.
Some plants want daily misting; others are OK with two to three times a week.
Set your mister on a timer for 10 to 15 minutes mid-morning," she suggests. "Alternately, set the plants in a tray of pebbles and hand-mist the pebbles and leaves with a mist sprayer. Avoid spraying directly onto the leaves. You want to create moisture in the air around the leaves.
Misting creates humidity, and some tropical plants appreciate it (though there are more effective methods for increasing humidity around your plants), but it should supplement watering. To water properly, pour water directly on the soil until it runs out the drainage holes at the bottom of the pot.
“Spritzing your plants is not the correct way to water your plants. In fact, it doesn't water them at all,” she says. While spritzing can provide some moisture, unless the plant really thrives in humidity (ferns, orchids, or bromeliads, for example), Hovis says spritzing can do more harm than good.
As a rule of thumb, all cacti, drought tolerant plants, and the great majority of succulents, should never be misted!
Types of Plants That Like Mist
Tropical houseplants and plants that love high-humidity—such as the Chinese Evergreen, Boston Fern, and Majesty Palm—will benefit most from misting, says Plunkett. (Zebra plants, orchids, arrowhead plants, and begonias are just a few others that love mist.)
Some plant owners mist the base of the plant and the surface of the soil, but this has little benefit. Don't worry about misting the soil because the water won't make it to the roots to be absorbed.
A: To a plant, there's no difference in the mist temperature. However, warm misting humidifiers sanitize the water as they heat it to vapor. That means there's a slightly smaller chance that humidity-borne diseases can develop with a warm mist temperature.
So, to avoid overwatering all you need to do is take a more measured approach. According to Reader's Digest, all it takes is placing two large ice cubes or several small ice cubes at the base of your plant once a week to keep them happy and hydrated. This way the plant gets to suck up all that H₂O slowly, but surely.
Too much of anything is not always a good thing. We think that it is appropriate to mist in doses of 1-2 times per week depending on the plant's temperament and environment. Over-misting plants can attract pests. Make sure to spray the undersides of leaves, lightly.
Use filtered or rain water that doesn't contain chlorine, fluoride or other chemicals. Always mist your plants in the morning so the leaves can dry out during the day.
A spritz as little as once or twice a week can make a huge difference to humidity here as the moisture has nowhere to escape to. Likewise, misting can be an effective way to target dry patches on hanging baskets or mounted plants, such as stag horn ferns, which traditional watering may miss.
Examples of some plants that don't appreciate misting are succulents and other drought-resistant plants like Aloe Vera and Jade Plants, as well as any plants that have fuzzy or hairy leaves, as it is easy to cause these kinds of leaves to rot if they get too wet.
“Some plants thrive in humidity,” explains Hank Jenkins of the Plant Provocateur in Silver Lake. “If you don't give them moisture, their leaves will dry out. If you want new foliage and growth, you need to mist them.”
As for misting — for the plants that need to be misted to thrive like air plants and ferns — it's best to mist them in the morning *and* the evening whenever possible. The morning mist helps to prepare them for the day ahead, while the evening misting helps create a little extra humidity.
Your Spider Plant will do well in normal household humidity but will thrive with a bit more humidity. Brown leaf tips may indicate the air is too dry, so mist your Spider Plant regularly using a Mister.
2. Misting. This method of watering is not recommended for succulents at all. Instead, you should only mist your succulents when propagating cuttings, as mature succulents store water in their leaves.
DON'T overwater.
Overwatering, however, increases the risk of root rot and fungal disease. If you see droopy stems, wilting leaves, a whitish coating (fungus), or fungus gnats in the home—pests that thrive on consistently wet soil—it's a good bet that you're watering plants too much.
Water Young Plants and Flowers Daily Until Established
Most young varieties call for daily watering (skip rainy days) until roots are developed, which happens around the two week mark. At that point, you can taper off and move to a weekly schedule if the variety allows.
