I'm trying this, I'll let you know how it goes. I have one African violet and I'm hoping to be able to strike more from it, so I need to keep it healthy and happy.
Dust African Violet Leaves
To keep your African violet plants healthy and help your plant to breathe through its leaves dust the leaves off periodically with a clean paint brush. When the plant's leaves are full of dust it cannot breath through its leaves and it cannot stay healthy. It really works! I have had no luck in getting blossoms on my African violet plants and now that I have been doing this they are full of blossoms.
