Talk about foolproof: begonias are about as easy as they get. They do well in a variety of conditions, but to keep it its most luxuriant best, give it light shade; rich, well-drained soil; and ample water. It also loves plenty of fertilizer, so be generous. Plant begonias in spring after all danger of frost has passed. No need to deadhead this flower unless you want to, it's "self-cleaning!"
