When to plant Lettuce in Comores
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 | 23 Feb 2027 – 27 Mar 2027 opens in 21 weeks | 10 Jun 2027 – 9 Aug 2027 |
| Expected harvest | about 10.7 t/ha | about 23.3 t/ha |
| Harvest | From 9 Apr 2027 to 10 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 11 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Comores is close to normal, so these dates match the pattern the area usually follows.
Planting after 27 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2025/26 season in Comores
| When the rains are expected | September 2025 to August 2026 |
|---|---|
| Rain in a typical year | About 1,686 mm in a typical farming district |
| Across its districts | From about 1,560 mm in the driest of 17 districts to about 2,242 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 1,686 mm falling roughly when it always does |
| 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 68% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 2,110 mm · September to September |
|---|---|

| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 342 growing days · about 1,850 mm · September to September |

What lettuce needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Spacing | 38 cm between rows, 30 cm between plants |

What it takes to grow lettuce in Comores
| Nitrogen (N) | About 27 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 54 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.
