Forced Dormancy Question
|
From: "Allan Tetzlaff" <atetzlaff at rogers.com> on 2007.01.07 at 17:28:58(15054)
I have bulbs of Typhonium venosum and I keep them
in the fridge during the winter so they don't start growing too soon in the
spring (the suggestion of the woman I purchased them from). I was
wondering if anyone has experience with any of the Amorphophallus species in
using this type of method to shift the growing season? Eg. My A.
haematospadix always grow during the winter and rest during the summer.
Though they're not big, they do take up space.... same issue for
paeoniifolius which are currently getting large. If they grow outside in
the summer that solves a few important issues. Any tips would be
appreciated. I'm not concerned about konjac as it seems to match our
season fairly well.
Thanks,
Allan Tetzlaff

I think you can put them in a fridge to keep them
cool.
There is a botanic garden not far from us, and they have A.

konjac. It emerged there in august and they keep them in greenhouse in the
winter time, but my one is dormant in winter and grows in summer. So you may try
it, but you may keep some offspring uncooled if anything would happen to the
cooled tubers...

Allan,
I haven't seen much response to your note, so here's a few comments. I have an
interest in this, too, since my indoor growing space is limited and dormant
things take up much less room.
Typhonium venosum (a.k.a. Sauromatum venosum and probably a dozen other things)
is quite hardy - I've grown it only outdoors here in NW Arkansas for many
years, even back when we had cold winters (-25 C or below) with no problems. It
flowers and sets seed every year. If you're not in a really brutally cold area,
you might consider the outdoor option.
As to Amorphs, I keep konjac outdoors, too, and although it took several years,
it finally did synch up with our seasons and seems perfectly acclimated.
I've had what I can only call very limited success trying to persuade other
Amorphs to change their dormancies for me. Most seem to go dormant and break
dormancy whenever they please, without regard to the seasons outside.
I've never been willing to risk Amorphs in the refrigerator - rightly or
wrongly, I've gotten the impression that many will rot if they get very cool -
but I do keep them coolish (12-15 C), and as dry as the individual species will
permit. The only positive results I've had, in fact, seem to be those that will
tolerate being unpotted and kept completely dry with no soil at all. At some
point, even those decide they're just going to start growing again, soil or
not, but I have gradually gotten some pushed around the calender a little.

My T. venosums, and also konjacs, are weeds here in the sandy subsoil of my coastal New Jersey, USA garden. Planted deep in the soil overlain by thick organic mulch, they flower in early May and are up in leaf towards the end of May. They never fail to spread by seeds or small offsets that make their way to the soil surface and are transported around.
