When to plant Lettuce in Magharibi
Mjini Magharibi, United Republic of Tanzania
Known here as saladi · letusi
Lettuce is a fast, leafy salad crop grown for its crisp, tender leaves — and because people eat it raw, you must grow it clean.

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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Magharibi is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow lettuce in Magharibi
| Nitrogen (N) | About 22 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 44 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.
