How to Grow Turmeric Tips
Turmeric, Curcuma longa is an edible, medicinal, attractive self-pollinating perennial plant. Turmeric is worthy of a place in everyone’s garden, even in a pot. I believe it is one of the most healing herbs you can grow and use for preventative health benefits. It’s a member of the ginger family and is known for good reason as the Spice of Life!
Where to Grow Turmeric – Likes and Dislikes
Turmeric is a rhizome (root crop) and is planted from a piece of turmeric rather than seed. It prefers a well-drained, consistently moist compost-rich soil in a partial to full sun location. Turmeric thrives in warm, humid subtropical and tropical climates protected from strong winds and frost. In these conditions, turmeric will grow with just morning sunshine. However it benefits from shade relief in intense heat, especially over hot summers.
If you are in a cool climate, plant it in a full sun position with maximum warmth. Avoid wet or waterlogged soil or the rhizomes can rot. Turmeric is sensitive to drought or drying out completely. Avoid frosty conditions or heat stress.
How to Grow Turmeric in a Container or Garden Bed
Use a nutrient-rich, moisture-holding potting mix and a thick layer of mulch. I have several in pots that just keep producing year after year with very little effort required to maintain them. The quality of the potting mix makes a HUGE difference, so don’t skimp.
If planting into a garden bed, improve the soil with plenty of compost and mulch. Turmeric is a hungry feeder! So prepare the soil well with nutrients (rock minerals and trace elements). Make sure the soil is well-drained so your crop doesn’t rot.
Turmeric is grown from plant material. Start with a large healthy organic turmeric rhizome. Ideally, it will have roots or small knobbly bits that are starting to shoot. The larger the original rhizome, the more energy the plant will have to grow and produce more turmeric. Makes sense right? So don’t skimp on your planting material! Sow 5cm (2″) deep and 15-20cm (6-8″ apart).
Always put a plant marker in the garden or pot. It’s easy to forget your dormant turmeric plant is there sleeping! You can lose it while it’s snoozing, accidentally damage it or forget to care for it. So label it well!
