When to plant Lettuce in Ongogni
Plateaux, Congo
Lettuce is a fast, leafy salad crop grown for its crisp, tender leaves — and because people eat it raw, you must grow it clean.

|---|---|---|
| Fit | Moderate | |
| When to plant | 5 Sep 2026 – 29 Nov 2026 open now | 21 May 2027 – 20 Jul 2027 |
| Expected harvest | about 9.9 t/ha | about 14.3 t/ha |
| Harvest | From 20 Oct 2026 to 12 Feb 2027, depending on the planting date | |

| 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 26 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ongogni 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 29 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Ongogni
| When the rains are expected | August 2026 to June 2027 |
|---|---|
| Rain in a typical year | About 1,377 mm |
| This season's rain | Leaning dry — January, September, October, 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 +1.2 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 95% of this area. |
| 95% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 317 growing days · about 1,360 mm · August to June |
|---|---|
| 5% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 317 growing days · about 1,340 mm · August to June |

What it takes to grow lettuce in Ongogni
| Nitrogen (N) | About 25 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 50 kg per hectare |

| 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.
