When to plant Cucumber in Omaruru
Erongo, Namibia
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 | 25 Jan 2027 – 24 Feb 2027 opens in 17 weeks | 30 Jun 2026 – 22 Mar 2027 |
| Expected harvest | 15.1–17.8 t/ha | about 37.1 t/ha |
| Harvest | From 11 Mar 2027 to 5 May 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 | 67% | |
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 4 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Omaruru is close to normal, so these dates match the pattern the area usually follows.
Planting after 24 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Omaruru
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For cucumber in Omaruru, 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 2026/27 season in Omaruru
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | December 2026 to April 2027 |
| Rain in a typical year | About 380 mm |
| This season's rain | Rain close to usual — plan around about 380 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.7 °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 short crop, and only if timed to it, 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 59% of this area. |
| 59% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 85 growing days · about 340 mm · January to April |
|---|---|
| 24% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 290 mm · January to March |
| 15% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 101 growing days · about 400 mm · December to April |

Limited water holds back about 35% of yield here.
What cucumber needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |

What it takes to grow cucumber in Omaruru
| Nitrogen (N) | About 27 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 45 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.
