When to plant Teff in Kiambu
Kenya
Teff (Eragrostis tef) is a fine, tufted grass that carries the smallest grain of any cereal in the world — seed almost as fine as dust.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 12 Apr 2027 – 25 Apr 2027 opens in 28 weeks | 1 May 2027 – 9 Aug 2027 |
| Expected harvest | 2.6–2.9 t/ha | about 3.5 t/ha |
| Harvest | From 11 Jun 2027 to 23 Aug 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 88–174 days per hectare, by hand | |
| Rain meets its needs | 98% | |
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 12 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Kiambu 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 25 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kiambu
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 88% |
For teff in Kiambu, the soil is the tightest of the three at 88%. 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 Kiambu
| When the rains are expected | December 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,375 mm in a typical farming district |
| Across its districts | From about 637 mm in the driest of 12 districts to about 1,446 mm in the wettest |
| This season's rain | Leaning wet — 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 7 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |

What teff needs to grow here
| Soil it likes | sandy loam, loam, clay loam or clay |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.2 and 5.8 |
| Feed it most with | phosphorus, nitrogen, zinc, sulphur and boron |
What it takes to grow teff in Kiambu
| Planting material | About 3,000,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 87 kg per hectare |
| Phosphate (P₂O₅) | About 29 kg per hectare |
| Potash (K₂O) | About 72 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 88–174 days per hectare, by hand |
These are the nutrients a teff 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.
