The African Hemp (or Room Linden) is famous for being low-maintenance, making it a total favorite for indoor gardeners who are still working on their green thumbs. But even with “easy” plants, seeing brown leaves can be a real bummer. Don’t worry, though—I’m here to help you figure out exactly what your plant is trying to tell you and how to fix it.

Reading Your African Hemp’s Leaves

The African Hemp isn’t just a pretty face; it actually communicates with you through its foliage. If your plant is unhappy with its environment, you’ll notice it in its appearance almost immediately. Usually, it’s nothing too serious, but you’ll want to act fast to keep your green friend happy. While serious diseases are pretty rare for these guys, most health issues usually stem from pesky pests.

Dealing with Brown Leaves

If you’re seeing brown spots or leaves that have turned completely brown, you’re likely looking at a case of sunburn. Even though the African Hemp loves a bright spot, it really can’t handle direct, harsh sunlight. A south-facing window is usually a no-go because that midday sun is just too intense. Instead, try a bright spot near a west- or east-facing window. If you move your plant out to the balcony for the summer, make sure it has plenty of shade!

What About Yellow Leaves?

Yellow leaves are a different story than brown ones. Yellowing is usually a sign of a deficiency—basically, your plant is crying out for more water or some extra nutrients. If you see this, it’s time to step up your watering game and add some fertilizer to the mix. Low humidity can also be the culprit. You can help your plant out by using a humidifier or giving it a regular misting with a spray bottle.

Dropping Leaves

If your plant starts dropping leaves, you need to jump into action just like you would for discoloration. There are a few reasons this happens: drafty spots, too much sun, or even using water that’s too cold. Both over-watering and under-watering can also cause a leaf exodus. In the best-case scenario, it’s just “moving shock”—sometimes a new plant just needs a little time to adjust to its new home in your house.
