When to plant Lettuce in Buhigwe
Kigoma, 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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 6 Feb 2027 – 30 Mar 2027 opens in 18 weeks | 2 Mar 2027 – 30 Jun 2027 |
| Expected harvest | about 20.2 t/ha | about 30.7 t/ha |
| Harvest | From 23 Mar 2027 to 13 Jun 2027, depending on the planting date | |
| Ready to harvest | 45–75 days after planting | |
| Work it takes | 40–80 days per hectare, by hand | |
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 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Buhigwe leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 30 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Buhigwe
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For lettuce in Buhigwe, 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 Buhigwe
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to May 2027 |
| Rain in a typical year | About 1,046 mm |
| This season's rain | Leaning wet — January, October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.0 °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 all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 69% of this area. |
| 69% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 238 growing days · about 1,060 mm · October to May |
|---|---|
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 273 growing days · about 1,200 mm · September to June |
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 280 growing days · about 1,320 mm · September to June |
| 5% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 244 growing days · about 1,180 mm · September to May |

What it takes to grow lettuce in Buhigwe
| Nitrogen (N) | About 50 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 20 kg per hectare |
| Potash (K₂O) | About 101 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.
