Begonias sprouted then rotted

raee_gwJuly 21, 2014

Hello, I've not grown tuberous begonias, only a long lived angel wing, which lived on a covered porch in the summer and a pot of the bedding wax begonias which I also overwinter.

I was able to get a dozen corms of non-stop and other "hanging basket" tuberous begonias on clearance this spring; they were solid and healthy looking and sprouted when I potted them up.

However, about half have rotted! Could it be that being on the uncovered patio, part shade, with all the rain we have had was too wet for them? I potted them in a mix of compost and peat with extended release fertilizer -- wrong? Should I repot them into a sterile commercial mix?

I want to save the remaining plants (some look fine, others seem to be struggling) so any advice would be appreciated!

Too wet I would say. The mix they sit on, not in, should be barely damp. When the little eyes show, then youcan pot them a little deeper. But remember, they will not tolerate being watered when they haven't really started growth.Experience is a good teacher,.

Thanks, woebegonia. At least if I get lucky next year I can use a better draining mix and keep them on the covered porch. I think that I will move the survivors to that porch before the next rain.
