African violets are very popular flowering plants. Small, easy to care for, and attractive, they’re often grown as houseplants. The watering needs of houseplants can be tricky, however, and inadequate watering can lead to serious problems. One very common problem is crown rot. Keep reading to learn more about how to spot crown rot in African violets and African violet crown rot treatment.

Crown Rot in African Violets

Also frequently known as root rot, crown rot develops when an African violet’s growing medium is too wet. There’s more at work than decomposition, however. Crown rot is a disease, and the disease is caused by a fungus called Pythium ultimum.

The fungus thrives in wet conditions, spreading through the growing medium and feeding on the plant’s roots and crown. If the fungus spreads too far (and the wetter it is, the quicker it spreads), it will kill the plant.

Controlling African Violet Crown Rot

Crown rot on African violet plants is evident in roots that become dark and soft. Unfortunately, the roots are hidden underground, so you won’t be able to notice this telltale symptom. And even more unfortunate, the most obvious above ground sign of African violet crown rot is leaves that wither, turn yellow, and eventually fall off.

This is unfortunate because it’s basically indistinguishable from the sign of an African violet that’s not getting enough water. Many African violet owners misread these symptoms and wind up overwatering a plant that’s already suffering from too much water. The best way to avoid this is to pay attention to soil moisture.

Don’t let the soil dry out completely, but let it become dry to the touch between waterings. The best method for controlling African violet crown rot is prevention – always let the soil dry to the touch between waterings.

Since there really isn’t an effective African violet crown rot treatment, if your plant is already infected, dispose of it and its growing medium, and sterilize its pot before using it again.
