Crown Rot On African Violets: Treatment for Crown Rot on African Violets

The African violet is one of the most 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. Crown rot is one of the most common problems. To learn more about African violet crown rot, as well as how it can be treated, keep reading.

Crown Rot in African Violets

An African violet’s growing medium becomes too wet, resulting in crown rot, also known as root rot. 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

The roots of African violet plants become soft and dark when they have crown rot. Unfortunately, the roots are hidden underground, so you won’t be able to notice this telltale symptom. 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.
