The other day I dug up some begonias I planted last spring, expecting
to find some form of tuber to store over the winter. However, I
didn't find anything resembling a tuber, just a root system. I know
there are two types of begonias (at least), but I was pretty certain
these were tuberous begonias. Might I have dug them up too soon? Or
perhaps too late? Will they survive the winter indoors as a potted
plant, seeing as how there's no tubers to salvage?
