Cucumber is a fast, thirsty climbing vine grown for its crisp young fruit — picked small and often, before the seeds inside go hard.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 16 Oct 2026 – 5 Nov 2026 opens in 2 weeks | 21 May 2027 – 9 Aug 2027 |
| Expected harvest | 17.8–20.6 t/ha | about 40.0 t/ha |
| Harvest | From 30 Nov 2026 to 14 Jan 2027, depending on the planting date | |
| Ready to harvest | 45–70 days after planting | |
| Work it takes | 120–247 days per hectare, by hand | |
| Rain meets its needs | 87% | |
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.
No seasonal forecast reaches Mandera yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 5 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mandera
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For cucumber in Mandera, the lie of the land is the tightest of the three at 76%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.

|---|---|
| Across its districts | From about 258 mm in the driest of 6 districts to about 322 mm in the wettest |
| This season's rain | Leaning wet — make sure water can drain off the field. |

What cucumber 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 |
| Rain it needs | About 1,000–1,200 mm across the season |
| Spacing | 150 cm between rows, 40 cm between plants |

What it takes to grow cucumber in Mandera
| Nitrogen (N) | About 37 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 21 kg per hectare |
| Potash (K₂O) | About 62 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 | 120–247 days per hectare, by hand |
These are the nutrients a cucumber 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.
