When to plant Watermelon in Marka
Lower Shabelle, Somalia
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 | 27 Mar 2027 – 16 May 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 25.4–30.2 t/ha | about 50.0 t/ha |
| Harvest | From 15 Jun 2027 to 3 Sep 2027, depending on the planting date | |

| Work it takes | 46–96 days per hectare, by hand | |
| Rain meets its needs | 88% | |
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 6 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Marka 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 16 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| The soil | 88% |
| The lie of the land | 96% |
For watermelon in Marka, the soil is the tightest of the three at 88%. 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.

What it takes to grow watermelon in Marka
| Planting material | About 4,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 97 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.
