When to plant Turmeric in iLembe
KwaZulu-Natal, South Africa
Known here as borrie
Turmeric is a leafy, ginger-like plant grown for the bright orange, aromatic rhizome (underground stem) hidden beneath it — the source of the yellow spice, the dye, and its own next-season seed.

Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 17 Nov 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for iLembe is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in iLembe
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For turmeric in iLembe, the lie of the land is the tightest of the three at 60%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.

What it takes to grow turmeric in iLembe

|---|---|
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 107 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 159–282 days per hectare, by hand |
These are the nutrients a turmeric crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
