When to plant Lettuce in Amajuba
KwaZulu-Natal, South Africa
Known here as slaai
Lettuce is a fast, leafy salad crop grown for its crisp, tender leaves — and because people eat it raw, you must grow it clean.

| Expected harvest | about 16.9 t/ha | about 32.4 t/ha |
| Harvest | From 11 Mar 2027 to 16 May 2027, depending on the planting date | |

| Rain meets its needs | 75% | |
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 18 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Amajuba is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Amajuba
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For lettuce in Amajuba, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Amajuba
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to April 2027 |
| Rain in a typical year | About 721 mm |
| This season's rain | Rain close to usual — plan around about 721 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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 | 3 kinds of ground. The season below is the largest that farms — about 59% of this area. |
| 59% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 210 growing days · about 740 mm · September to April |
|---|---|
| 38% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 219 growing days · about 750 mm · September to May |
| 3% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 213 growing days · about 740 mm · September to April |

What it takes to grow lettuce in Amajuba
| Nitrogen (N) | About 42 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 17 kg per hectare |
| Potash (K₂O) | About 84 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 | 40–80 days per hectare, by hand |
These are the nutrients a lettuce 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.
