Finally broke down and made some ginger tea. The roots (technically rhizomes) were busting out of a plastic pot so I cut off one and cleaned and sliced it as fine as possible. Then I put about a heaping teaspoon of this with a like amount of dulce, covered it with Boiling water, and let it steep for 10 minutes. It's a pleasant drink, with a little more fire than the commercial ginger teas. You can adjust the bite and the sweetness to your tastes.
Ginger grows well here in partially shade. Plant has attractive foilage, a little like bamboo. Flowers are strange and not a big plus. At the end of the rainy season the tops dry out and the roots can be harvested when needed. Next year I`'m, going to plant all of mine in pots to improve the soil and make harvesting easier. The equivalent to 3 gallon size or larger should work for one plant. they appear to be shallow-rooted, so a pot wider than taller would be best. Plants in the (heavy clay) ground take no care but are hard to harvest.
