Re: [Aroid-l] Amorphophallus under lights


I can't address your question in detail, having just three winters' experience in the distant past, but you had better watch out for spider mites. They were by far my worst problem when wintering plants in my basement.

Regular spritzing of all above-ground plant surfaces with plain water or rubbing alcohol (isopropyl alcohol 60% - 80% in water) will do the trick. You will have to be careful not to wet the soil if you are trying to keep it dry. And, do the spritzing when the high-pressure sodium lamp is off and cool unless you like explosions involving flying superheated glass.

If I didn't spritz all my plants - cactus, leafy things, whatever - once a week, I had severe spider mite damage in a jiffy. The most susceptible plants, in order of severity, were

aroids / Lobivia cacti (tie)
jasmine
Brugmansia

Hello fellow Amorph-o-philes,

I live in zone 6a and do not have a greenhouse. I have maybe 20-30 species of Amorphophallus (at some point I need to make a list) and until this year just nursed them along as long as possible in my cold climate until dormancy set in due to a lack of both sun and cold. Unfortunately, I had maybe 40 pots full decide to not break dormancy this year until August and so my usual plan of attack was out of the question. Thus, I now have quite a few under a 400W MH HID grow light and after 3 weeks they are doing wonderfully, except for the aphids which have already proven to be a pain in the backside! I was wondering if anyone could provide any additional thoughts on care as we move further into the fall/winter. These are sitting on a table, not on the floor and so I think there will likely be enough heat for them (no cold basement floor). I also have 2 separate fans continuously blowing to keep excellent air circulation. I have not bothered to mist them at all to date an
d no one seems to mind, although it has only been three weeks.  Certainly I can not be the only one growing Amorphophallus through the winter under lights and so I would truly appreciate the thoughts of the long-term growers on this forum.  Thanks in advance for any help you can provide,
