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 27 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Windhoek Rural leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 5 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Windhoek Rural
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | January 2026 to April 2026 |
| Rain in a typical year | About 404 mm |
| This season's rain | Leaning dry — January and February look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +2.2 °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 short crop, and only if timed to it, 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 35% of this area. |
| 35% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 97 growing days · about 390 mm · January to April |
|---|---|
| 33% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 280 mm |
| 9% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 180 mm |
| 9% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 330 mm |

What lablab needs to grow here
| Soil it likes | well-drained sand, sandy loam, loam, clay loam or clay soil |

| Soil sourness (pH) | Happiest between pH 5.0 and 7.5 |
| Spacing | 75 cm between rows, 30 cm between plants |

What it takes to grow lablab in Windhoek Rural
| Nitrogen (N) | About 52 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 13 kg per hectare |
| Potash (K₂O) | About 18 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 75–156 days per hectare, by hand |
These are the nutrients a lablab 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.
