When to plant Watermelon in North Imenti
Meru, Kenya
Known here as tikiti maji
Watermelon is a warm-season trailing vine, grown flat along the ground for its big, sweet, thirst-quenching fruit — a cousin of pumpkin, cucumber and melon.
| Measure | Rain-fed | With irrigation |

| Fit | Favourable | |
| When to plant | 22 Feb 2027 – 20 Mar 2027 opens in 21 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 30.7 t/ha | about 43.9 t/ha |
| Harvest | From 13 May 2027 to 8 Jul 2027, depending on the planting date | |

| Work it takes | 46–96 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 22 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for North Imenti 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 20 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in North Imenti
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For watermelon in North Imenti, 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 season in North Imenti
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 1,023 mm |
| This season's rain | Leaning wet — January, February, 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 +0.9 °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 41% of this area. |
| 41% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 243 growing days · about 1,070 mm · February to June |
|---|---|
| 17% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 289 growing days · about 1,700 mm · September to July |
| 17% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 256 growing days · about 1,310 mm · September to June |
| 10% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 264 growing days · about 1,460 mm · September to June |

What it takes to grow watermelon in North Imenti
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 68 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 98 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. |

These are the nutrients a watermelon 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.
