I just dug up some begonias I'd planted early this year, expecting to
find some kind of tuber to store over until next winter. But alas,
there was nothing but a root system down there. I know there are at
least two different types of begonias, but I was sure this was the
tuberous kind. Could it be that I dug it up too early? Too late
tham and there when you dig them up to store. In fact, the tubers just keep
increasing in size over time. The only way they would not be present if they
were the tuberous type of begonia is if they had rotted, but your plants
would have died in that case and it would have been obvious.

It has been my experience that "non-stop" tuberous begonias do not produce
that same type of big tuber at the end of a season that other
bigger-flowered varieties do. Perhaps these plants are usually grown from
seed or from cuttings rooted the previous winter and therefore have not had
the time to develop a big juicy tuber - I'm not sure. But while they bloom
prolifically all summer long, they usually don't have much of a tuber at all
under the soil come late fall- sometimes nothing but a mass of roots. I
usually relate them to the small dahlias raised from seed - which usually
also do not produce much of a tuber by summer's end.
You're correct in stating that "non-stops" do no produce much of a tuber the
first year. The ones I purchased were started from seeds, a bonus in their
reproduction, and were small seedlings when purchased. They did grow and
bloom well the first year (zone 3), but the tuber they produced was almost
non-existent. I found that most of these tiny tubers dried up and died if
dug up and stored. To counteract this, I left them in the pots in which they
were growing with the growing medium, and watered a couple of times during
the storage period. By the end of the second year, most of them had
developed large enough tubers to survive normal storage methods, and by the
third year many of them produced tubers as large as the those regularly
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?
Sorry about that redundant post. Nothing showed up for a day or two,
so I reposted the question.
I potted up the begonias this morning. I've put them in a north
window, assuming they'd appreciate a lot of indirect light.
One branch snapped off while potting them, so I stuck it in a
container of water hoping that it will root. Or would I be better off
adding some rooting hormone and putting it in a pot of soil?
