  A. prainii care instructions
From: Kirk Martin kwmartin at earthlink.net> on 1970.01.01 at 00:00:00(13527)
Hello,

I'm just trying to find some basic care instructions for growing
Amorphophallus prainii. The plant is approximately 10" tall now and
appears to be actively growing (was given plant in early October this year).

I'm growing the plant in a 50 % loam and the remainder in 1:1:1 peat, perlite, vermiculite under
a 4' fluorescent light.

Since I live in Fitchburg Massachusetts, Can I expect a dormancy and if so any idea when it would start?
Just trying to get a sense how finicky this plant is and how susceptible to rot.

Anyone have a fact sheet? All I know is it's habitat is near Thailand/ Indonesia and not much more.

Any help is appreciated,

Kirk Martin

Hi Kirk,

I have very little experience with this plant outside of killing one
last year. Therefore, I can say it is *very* prone to rot if you keep it
damp and cold at the same time. Many amorphs have this tendency.

My current plants of this species are all seedlings, and they've put up
leaf after leaf after leaf and are still going strong in the greenhouse.
I really wish they'd go dormant! It's time to let my CT greenhouse go cold.

Here's my advice for yours: if it's had a good long growing season and
keeping it growing is inconvenient for you, stop watering and it will go
dormant. My friends on this list will yell at me if my advice is wrong
and then we'll both learn better...

I find this species very easy to grow......just like A. paeoniifolius. If your plant is a seedling, you can expect it to produce a series of leaves before it enters the first dormant phase. I've had them stay up for two years during this phase. Once the first dormancy sets in, it will establish a growth cycle similar to paeoniifolius, coming up in the late spring when the soil gets warm enough and going down at the end of the growing season. Here in Florida, mine are just now showing early signs of dormancy. At the end of the growing season, I unpot the corm, clean off the soil and inspect the corm, then replant it and let it stay dry until it comes up in the spring. My flowering plants produce leaves between 6 and 8 feet tall. My plants have never produced offsets and flower every year.

Hi Ron,

Just chuckling a bit since my A. paeoniifolius just broke dormancy early to mid September.
and is only now getting started to grow (not a good survival strategy in New England zone 5).
Seems to be growing indoors fine right now.
I'll just try to keep the A. prainii growing along through the winter (there are currently 3 leaves on it 2 semi-dried and
the third center leaf looks green and healthy.
Thank you and Ken M. for your helpful hints.

We have huge ones here at Smith College in Northampton, about an hour away from you at our Botanic Garden. They are in the conservatory. Feel free to visit.
