When to plant Sunflower in Embu
Kenya
Known here as alizeti
Sunflower is a tall, upright plant — about 1–2 m, higher than your head — that carries one big flower head on top.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 13 Feb 2027 – 5 Mar 2027 opens in 19 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 2.0–2.2 t/ha | about 3.1 t/ha |
| Harvest | From 14 May 2027 to 13 Jul 2027, depending on the planting date | |
| Ready to harvest | 90–130 days after planting | |
| Work it takes | 74–155 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 23 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Embu 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 5 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Embu
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For sunflower in Embu, 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 Embu
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | October 2026 to January 2027 |
| Rain in a typical year | About 669 mm in a typical farming district |
| Across its districts | From about 669 mm in the driest of 4 districts to about 2,002 mm in the wettest |
| Rainy seasons, district by district | Of 4 districts: one rainy season in 1 and two rainy seasons in 2 |
| This season's rain | Leaning wet — January, 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 +0.9 °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 | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 38% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 215 growing days · about 780 mm · October to January |
|---|---|
| 26% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 156 growing days · about 610 mm · October to January |
| 18% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 248 growing days · about 970 mm · September to June |
| 9% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 346 growing days · about 1,810 mm · February to January |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 1,720 mm · January to December |

What it takes to grow sunflower in Embu
| Planting material | About 50,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 99 kg per hectare |
| Phosphate (P₂O₅) | About 44 kg per hectare |

These are the nutrients a sunflower 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.
