Gingers and rot

OK, some background...I have a greenhouse with a min temp of around 55*F. In it, I have 24" tall raised beds with a pretty good mix of loam/peat/compost. I am working on a "tropicalscape" in the GH using a variety of plants. Many, perhaps most of these plants are evergreen and receive at least some watering through the winter.

My question is this: which gingers are prone to rot if planted in the GH raised beds where they will get some water through the winter?

SB, I don't think you should have a problem with any of the gingers in the beds, if your soil is built up and the drainage is good-i.e. lots of composting bark and peat etc in there. Ginger rhizomes rot when they sit in water-esp in cold weather and I don't see that happening in a sunny, warm grhouse where the watering is controlled and done on an "as needed" basis.
A lot of the curcumas die back in the winter-some of mine have and some are still going...
The hedychiums may or maynot bloom for you in the winter-I am not sure, but the shorter days may affect the blooming, but I would be prepared for them to rapidly take over a spot, and fill out.
The alpinias will grow a bit slower, and probably be affected even more by the shorter days-IMO.

Unfortunately, I think there is a shortage of people with experience with having actual growing beds in grhouses-either we have them in the ground outside, or in pots sitting out the winter in the grhouse....so I hope this helps some-perhaps others has some experience with this situation, or opinions

Thanks, TL.

I guess I'm curious because I have some gingers coming, and I just dug up a rotten heliconia. It was in one of the raised beds, but on the northeast corner of the greenhouse up against an uninsulated brick kneewall. I think it got too cold and too wet in that location.

So maybe it is just a matter of adjusting the watering...but with a variety of gingers coming, I wanted to try to position them in the greenhouse in part according to their resistance to rot.

Cut down the water and add shredded hardwood mulch to your soil!!
