Begonias have been favored for shade gardens for years and the large-flowered tuberous varieties represent royal blood. These have much bigger blooms and greater plant strength than the seed-grown types, which tend to be small, fragile and often a bit fussy looking. Like true queens, tuberous begonias aren't inclined to relinquish their throne after a single season. These tubers are easy to lift and store for many years of magnificent displays. We know a woman who has been growing the same begonia tubers for almost 10 years. Ever wanted to rub elbow.
Find a location where the soil drains well. If there are still water puddles 5-6 hours after a hard rain, scout out another site. Or amend the soil with the addition of organic material to raise the level 2"-3" to improve the drainage. Peat moss, compost, ground bark or decomposed manure all work well and are widely available. While begonias prefer a slightly moist soil, they wiill not survive in soggy soil.
