When to plant Cotton in 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.

Harvest	From 19 Mar 2027 to 7 Jun 2027, depending on the planting date

Rain meets its needs	48%

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 9 Nov 2026. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for South Africa leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.

Planting after 9 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

What decides this in South Africa

Rain and temperature	88%
The soil	96%
The lie of the land	96%

For cotton in South Africa, rain and temperature is the tightest of the three at 88%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.

The 2026/27 season in South Africa

Rainy seasons	One each year — one chance to plant, so timing carries it
When the rains are expected	October 2026 to April 2027
Rain in a typical year	About 622 mm in a typical farming district
Across its districts	From about 72 mm in the driest of 52 districts to about 1,130 mm in the wettest
This season's rain	Leaning dry — January, February, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early.
This season's heat	Hotter than usual — about +1.9 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can.
What that supports	enough rain for one full main crop, warm, with a cool spell that slows winter growth
Ground this covers	6 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area.

Agro-ecological zones covering this area
48%	too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 260 mm
13%	enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 146 growing days · about 540 mm · November to April
10%	enough rain for one full main crop; warm, with a cool spell that slows winter growth 212 growing days · about 750 mm · September to May
6%	enough rain for one full main crop; cool for part of the year, so frost sets the planting date 211 growing days · about 700 mm · October to April
3%	enough rain for one full main crop; warm, with a cool spell that slows winter growth 192 growing days · about 630 mm · October to April
3%	enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 128 growing days · about 510 mm · November to March

Limited water holds back about 45% of yield here.

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
Feed it most with	nitrogen, potassium and boron

What it takes to grow cotton in South Africa

Planting material	About 80,000 plants per hectare
Nitrogen (N)	About 39 kg per hectare
Phosphate (P₂O₅)	About 20 kg per hectare
Potash (K₂O)	About 42 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.
