Turmeric
Curcuma longa
herbTurmeric is a tropical ginger relative grown for its vivid orange-fleshed rhizomes, the source of curcumin and the golden color of curry. It forms tall, broad-leaved clumps and needs a long warm season of eight to ten months, so it is usually grown in containers outside frost-free regions.

🌱 Growing Guide
Presprout rhizome pieces indoors in late winter, then plant them 2 to 4 inches deep, buds up, once soil is reliably warm. Turmeric wants rich, well-drained loam, dappled shade in the hottest climates, steady moisture, and monthly feeding. It has zero cold tolerance and collapses below 50F, so grow it in a pot in cool regions and bring it indoors before frost.

🌾 Harvest & storage
Harvest after eight to ten months once the leaves have fully withered and before frost, digging the whole clump. Boil and dry the rhizomes for ground turmeric, or use them fresh; save a few buds to replant.
