You can grow your own turmeric and here are the instructions how to do it.
Grow Your Own Turmeric
To grow turmeric, you need roots, called rhizomes. The rhizomes should be planted in spring. So, now it is the right time. From one rhizome, you can grow a few plants. Every rhizome has fingers. If you shape them you can plant them for individual plants, or you can just use the rhizome for one plant.
If you notice any sprouts or buds, face them upwards. Plant the pieces, but leave 12 inches place between them. You should plant it 2 inches deep. Just press them gently and flatten the soil on the top.
The best location for the turmeric is the one with sunshine in the morning but with shade in the afternoons. The soil must be rich and moist. But, don’t overwater it.
Turmeric desires tropical zones and can grow for 8-10 months. When the plant begins to turn yellow and shrivel, harvest the roots. Just dig out the whole plant. You can keep the rhizomes for the next year.
But you can leave them in the ground too. The next spring they are going to sprout.
If you are in the cold climatic zone, then transplant the turmeric into containers and move them inside through the winter. Keep the soil moist, and spray the turmeric. When the plant becomes mature, it will turn yellow and is going to dry. Then, dig the whole plant, remove the roots and keep some of them for the next year.
The roots can be stored in the fridge for about six months. Turmeric also can be frozen.
Problems and Pests
Turmeric that is grown outside is a low-maintenance plant and usually it is resistant to various problems and pests. If you overwater it, the roots may rot.
Both, indoor and outdoor turmeric plants are sensitive to aphids and mites, but these can be easily cleaned with a spray of a bottle.
