The hanging begonia variety you bought you bought has a great name as the blooms are as bright at flre crackers. It is easy to care for. Water when the top inch of soil feels dry but like all begonias keep it our of the afternoon sun. Feed with a slow release plant food like Osmocote but do not overfeed. Pinch back the faded flowers after they bloom to keep new buds coming. You can prune a bit if the plant looks leggy in August. Just remove the last six inches of new growth by pruning the branches back at a joint or node. New growth will resume for a more bushy plant. Good job Bob. we should all come home with new plants when we go grocery shopping. Keep Growing, Marianne
