HELP! I have just ordered some tuberous drosera tubers. I forgot how
helpless I am with these! Does anyone have some suggestions, do's and
dont's about growing them? I would really like to get mine growing an a
northern Hemisphere cycle. I think I will try an experiment on one of
the less desirable tubers. Giberellin is a plant hormone which can be
used to break dormancy in seed and other under- ground plant organs. I
will see if a little giberellin dip might get one of these tubers
growing.

Barry: you wanted to keep yours dormant by planting them and keeping
them warm? My uneducated guess would be that if you want to keep them
dormant, keep them right in the bag. As soon as you bury those puppies
they will be exposed to every kind of fungus, bacteria, virus, slime
mold, insects, protists, and alga which breed in the dirt. Plant them
if they start to grow in the bag. I would also say, keep them cool
rather than warm. They are trying to ride out the hot Australian
summer, but the tubers are cool and deep down under (the soil). My big
question is: what triggers the end of dormancy. Is it an internal
(hormonal) or enviromental (temp, moisture) signal??? Barry, if you are
writ- ing Lowrie again I would ask him everything about dealing with
dormancy.
