When to plant Cabbage in Roysambu
Nairobi, Kenya
Known here as kabichi · kabeji
Cabbage is a cool-season leafy vegetable that packs its whole harvest into one dense, round head on a short stem.
| Fit | Favourable |
|---|---|
| When to plant | 11 Apr 2027 – 20 Jul 2027 opens in 27 weeks |
| Expected harvest | about 49.7 t/ha |
| Harvest | From 10 Jun 2027 to 7 Dec 2027, depending on the planting date |
| Ready to harvest | 60–140 days after planting |
| Work it takes | 118–211 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 11 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Roysambu 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 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Roysambu
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For cabbage in Roysambu, 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.
The 2026 season in Roysambu
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 748 mm |
| This season's rain | Leaning wet — January, February, October, 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 +1.0 °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 | 2 kinds of ground. The season below is the largest that farms — about 70% of this area. |
| 70% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 191 growing days · about 730 mm · February to June |
|---|---|
| 30% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 230 growing days · about 840 mm · February to June |

|---|---|
| Nitrogen (N) | About 149 kg per hectare |
