Powdery mildew is a common disease affecting many different houseplants, including jade plant, African violet, begonia, kalanchoe, and others. Powdery mildew appears as a white, dusty growth on the surfaces of leaves. The growth may appear in circular spots that coalesce or may cover the entire surface of the leaf. Severely affected leaves may be distorted.
Proper pruning of raspberries is essential. Pruning produces higher yields, helps control diseases, and facilitates harvesting and other maintenance chores. Pruning procedures are based on the growth and fruiting characteristics of the plants.
