| When to plant (establish) | 6 Feb 2027 – 8 Mar 2027 opens in 18 weeks | 21 Jan 2026 – 1 Jan 2027 |

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 8 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Embakasi West 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 8 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Embakasi West
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For mandarin in Embakasi West, 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 season in Embakasi West
| 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 663 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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | This area is smaller than the climate grid can resolve, so it reads as one kind of ground. |
| 33% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 179 growing days · about 660 mm · February to June |
|---|---|
| 33% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 230 growing days · about 830 mm · February to June |
| 33% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 181 growing days · about 660 mm · February to June |

|---|---|
| Nitrogen (N) | About 16 kg per hectare |

These are the nutrients a mandarin 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.
