Name: Anne Summerville, SC (Zone 8a) Only dead fish go with the flow!
I have all of my Hedychiums in the ground along with the Curcuma Hidden Gingers and Spiral Ginger, Costus pictus which gets full blazing hot sun from sun up til about 4 in the afternoon. The Hedychiums and Hidden gingers are solid zone 8 hardy .. I'm too chicken to risk putting my "specials" in the ground. I don't have a recent picture of the "Ginger Bed" but I'll take one tomorrow. I finally for the first time in like 4 years dug up the whole bed thinned out and replanted in late Winter of this year.
I find that the more water in the Spring and early Summer they get the faster they grow and sooner they bloom. I also throw time release fertilizer on top of the soil as well.
Here is the "key" to the Ginger Bed.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
