When to plant Cotton in Ugu
KwaZulu-Natal, South Africa
Known here as katoen
Cotton is grown for one thing: the soft white fibre — the lint — that grows wrapped around the seeds inside a pod called a boll.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 9 Aug 2026 – 17 Nov 2026 open now | same |
| Expected harvest | about 1.9 t/ha | about 3.1 t/ha |
| Harvest | From 6 Jan 2027 to 15 Jun 2027, depending on the planting date | |
| Ready to harvest | 150–210 days after planting | |
| Work it takes | 91–187 days per hectare, by hand | |
| Rain meets its needs | 94% | |
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 28 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ugu is close to normal, so these dates match the pattern the area usually follows.
Planting after 17 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ugu
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For cotton in Ugu, 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 cotton needs to grow here
| Soil it likes | well-drained sandy loam, loam, clay loam or clay soil |

| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Spacing | 90 cm between rows, 25 cm between plants |

What it takes to grow cotton in Ugu
| Planting material | About 80,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 53 kg per hectare |
| Phosphate (P₂O₅) | About 27 kg per hectare |
| Potash (K₂O) | About 57 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 | 91–187 days per hectare, by hand |
These are the nutrients a cotton 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.
