The raised bed that had the ginger family plants really did pretty well by the end of the season. They typically take longer than one growing season to produce mature rhizomes, so we decided to dig them up and save them for next year.
The plants all grew well this year, once they were established. The cardamom was by far the smallest, shown here in the very front. When the nights started getting down into the 40s, we decided to pot them up. We tried to dig up a large root area to keep them growing well. We moved them into my office under my light stand.
I did pull off a piece of each of the three edible rhizomes. (The cardamom has small rhizomes. The spice part is the seed pod. This takes about 3 years to develop.) The light pink rhizome on the left is the greater galangal. The center rhizome is turmeric, and the right rhizome is the ginger. Technically, all of the rhizomes could be used at this stage, before they develop the fibrousness and skin typical of the mature root. They are crispy, succulent, and fragrant at this stage. Of course, they wouldn’t last long without the skins.
You could also regenerate the plant from these pieces. Each of the little nodules or pointy nodes you can see on the rhizomes will grow a new shoot.
The plan for now is to keep the plants alive for the winter. Or, at a minimum, keep enough of the rhizomes alive to regrow next year!
