When to plant Lettuce in Central Tongu
Volta, Ghana
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 | Moderate | |
| When to plant | 28 May 2027 – 25 Jun 2027 opens in 34 weeks | 30 Jun 2027 – 9 Aug 2027 |
| Expected harvest | about 7.1 t/ha | about 13.0 t/ha |
| Harvest | From 12 Jul 2027 to 8 Sep 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 meets its needs | 97% | |
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 25 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Central Tongu 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 25 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Central Tongu
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 971 mm |
| This season's rain | Leaning dry — September and October 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 +0.5 °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 all year, so nothing but rain ends the season |
| Ground this covers | 3 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 262 growing days · about 970 mm · March to November |
|---|---|
| 25% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 270 growing days · about 1,020 mm · February to November |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 259 growing days · about 940 mm · March to November |

What it takes to grow lettuce in Central Tongu
| Nitrogen (N) | About 18 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 7 kg per hectare |
| Potash (K₂O) | About 36 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.
