Houseplants have a way of making any home feel a little more alive—even in the dead of winter. When you have succulents basking in the sunlight on your kitchen windowsill or a ficus tree towering over the couch in your living room, it’s hard not to feel more energized in their presence. But while indoor plants seem to transform any living space into a lush garden, their impact is only possible if your collection has leaves that are fresh, full, and vibrant—not drooping or dropping.
If leaf drop has been plaguing your indoor plants, there’s no need to panic! While it might not look like a sign of healthy houseplants, falling leaves is a normal part of many plants’ life cycle—lower leaves naturally die and fall off—and it’s totally fixable. But if your houseplant is shedding a lot of leaves at once or releasing its bright green ones, there might be a larger underlying issue. (But, again, there’s a solution!)
In order to restore your houseplants, you’ll first need to diagnose the problem, which is why we’ve rounded up seven of the most common causes of leaf drop. Once you’ve identified the issue, you can figure out the right solution, which we’ve also broken down below. As you start taking action, your plants can turn things around pretty quickly. Before you know it, they’ll be back to their thriving condition!

Overwatering
Overwatering your houseplants is the most common cause of leaf drop. When your greens are a little too hydrated, their leaves can turn a yellow or brown shade and develop a limp or mushy texture. Since indoor soil takes longer to dry in the colder months, your plants will naturally get less thirsty. Instead, a good rule of thumb is to wait to water your plants until the top two inches of soil are dry.
Underwatering
While giving your plants too much water can lead to leaf drop, the opposite is also true. If you skimp on your houseplants’ hydration, their leaves will soon become brown, dry, and crunchy before fully falling off. To prevent underwatering, check the moisture levels on a weekly basis. When the top two inches are dry, take it as your cue to saturate the soil.
Insufficient Sunlight
If your plants aren’t getting adequate light, their leaves will typically turn yellow before dropping. While this might not necessarily be an issue in the spring or summer, during the winter, sunlight levels tend to be lower, weaker, and less direct, which can negatively affect your plants—even the ones sitting on your windowsill. If you suspect insufficient sunlight might be to blame, move your houseplants to the sunniest spot of your house, or give them a boost with artificial lighting.
Low Humidity
Since many houseplants are tropical species, they thrive in humid conditions. But because indoor air typically dries out during the winter months, plants often release their leaves to conserve moisture. While this is a natural response, you can keep the leaves intact by placing potted plants on a tray of moist pebbles or regularly spraying them with water.
Extreme Temperatures
Just like indoor plants come alive in humidity, they also crave warmth. While you likely keep your thermostat within houseplants’ preferred temperature range of 60 to 75 degrees Fahrenheit, if your greens are sitting near a drafty window or door or a hot radiator or heat vent, they’ll begin to drop their leaves. To prevent temperature extremes from hurting an otherwise healthy plant, place yours in a safe location exposed to mild conditions.
Environmental Changes
Sudden and extreme environmental changes will also stress your houseplants out, prompting them to lose their leaves. If you move your plant to a new location that isn’t conducive to its health (see above), or if you repot it outside of growing season or place it in a too-large pot, you run the risk of hurting its leaves. If you sense yours needs to recover, keep it in stable conditions with adequate sunlight and water.
Pests
When pests, such as mealybugs, spider mites, and scale insects, infest houseplants, the plants conserve their energy by shedding their leaves. As you care for your indoor plants, be on the lookout for telltale signs of pests: sticky residue, fine webbing, discolored spots, distorted leaves, or visible bugs. Once you’ve detected the issue, treat your plants with insecticidal soap, and the leaf drop will soon stop.
