Sclerotinia (White Mold) Plant Care Advice

What is Sclerotinia (White Mold)?

Sclerotinia, also known as white mold, is a fungal disease that affects a wide range of plants, including indoor plants. It is caused by the fungus Sclerotinia sclerotiorum, which produces small, white, cotton-like growths on the stems and leaves of infected plants. These growths are actually the fruiting bodies of the fungus, and they produce spores that can spread the disease to other plants.

Sclerotinia is a common problem in indoor gardens, particularly in humid and poorly ventilated environments. It can be spread through contaminated soil, water, or air, and can also be introduced through infected plants or plant material.

How to Identify Sclerotinia (White Mold)

Identifying Sclerotinia can be challenging, as the early stages of the disease may not display any obvious symptoms. However, as the disease progresses, you may notice the following signs:

- White, cotton-like growths on the stems and leaves of the plant
