White mould, also known as sclerotinia, is a typical plant disease. White mould is also commonly referred to as stem rot, wilt and head rot. The mould appears fuzzy with a bright white colour. The mould is found on the tips of leaves of indoor and outdoor houseplants. However, white mould can also show up in other areas of in your home. The white and fuzzy mould grows due to an excess of water in area. For example, white mould can sometimes appear on flooded drywall. The white mould must be treated immediately.
Remove any leaves from house plants that have white and fuzzy mould on them by clipping them off from the stem using scissors. It's important to remove these diseased leaves immediately and other leaves which have dropped off from the plant. Wear latex gloves when removing the leaves.
Spray the plant with an fungicide spray after removing the diseased leaves. Such disinfectants can be found at your local garden store and should require only one or two small applications a day. This will help to prevent any fungus from growing back on your plant.
Reduce the watering of your plant, as the mould was most likely caused from over-watering. You should only water the plant when the soil is completely dry or use about 1 cup of water a day, depending on the size of the plant.
Stop any water leakage in your house if you have the white and fuzzy mould on areas such as walls or cabinets. Find any area that may be leaking water and affecting the spot and to patch it up to stop the leak.
Remove the mould from drywall and infected areas by carefully cutting it using a sharp knife. Wear latex gloves when doing this. Soak the mould area with soap and water before cutting it out. In most cases, you'll then need to replace the area of drywall. The most effective way to stop the white mould is to completely remove it from the area to stop it from spreading.
