What grows in Roysambu
Nairobi, Kenya
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 |

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.
What grows in Roysambu with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it
The crops and dates above are read at cells spread across Roysambu, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Roysambu?
Pineapple, African nightshade, Beetroot, Carrot, Common bean all rate well in Roysambu — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Pineapple in Roysambu?
In Roysambu the window for Pineapple runs 24 Sep 2026 to 14 Oct 2026.
Is there a farming app that works in Roysambu?
Divisi does. It reads Roysambu's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Roysambu, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
