When to plant Cucumber in Rwanda
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 | 28 Sep 2026 – 11 Apr 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 20.7 t/ha | about 40.0 t/ha |
| Harvest | From 12 Nov 2026 to 20 Jun 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-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 13 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Rwanda 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 11 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rwanda
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For cucumber in Rwanda, the lie of the land is the tightest of the three at 60%. 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.
The 2026/27 season in Rwanda
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to June 2027 |
| Rain in a typical year | About 723 mm in a typical farming district |
| Across its districts | From about 681 mm in the driest of 30 districts to about 1,379 mm in the wettest |
| This season's rain | Leaning wet — January, February, 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 +1.2 °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 | 6 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 38% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 323 growing days · about 1,060 mm · August to July |
|---|---|
| 25% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 278 growing days · about 730 mm · September to June |
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 280 growing days · about 790 mm · September to June |
| 9% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 265 growing days · about 740 mm · September to June |
| 8% | 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 1,360 mm · January to December |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 324 growing days · about 1,080 mm · August to July |

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 |
| Feed it most with | nitrogen and potassium |
What it takes to grow cucumber in Rwanda
| 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.
