I planted three begonias in a hanging basket. They have filled the basket with foliage but only 1 or 2 blooms and not very big ones. (One you can hardly see because the leaves are so big). The neighbor across the way has hers in hanging baskets on her porch and they are blooming like crazy. What do I need to do or not do? ( I am to embarrassed to ask her since I am the neighborhood green thumb)
