When to plant Lime in Kirinyaga
Kenya
Known here as ndimu
The lime is a small, thorny, evergreen citrus tree — the most heat-loving and least cold-hardy of the whole citrus family.

| When to plant (establish) | 14 Feb 2027 – 22 Mar 2027 opens in 19 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 15.6 t/ha | about 23.2 t/ha |
| Work it takes | 96–203 days per hectare, by hand | |
| Rain meets its needs | 99% | |
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 10 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Kirinyaga 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 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kirinyaga
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For lime in Kirinyaga, 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 2025 season in Kirinyaga
| When the rains are expected | December 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 1,977 mm in a typical farming district |
| Across its districts | From about 1,009 mm in the driest of 4 districts to about 1,977 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 | 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 239 growing days · about 920 mm · February to June |
|---|---|
| 24% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 345 growing days · about 1,610 mm · February to January |
| 10% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 258 growing days · about 1,210 mm · September to July |
| 9% | 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 1,750 mm · January to December |
| 3% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 365 growing days · about 1,780 mm · January to December |

What it takes to grow lime in Kirinyaga
| Planting material | About 340 plants per hectare |
|---|---|
| Nitrogen (N) | About 31 kg per hectare |
| Phosphate (P₂O₅) | About 6 kg per hectare |
| Potash (K₂O) | About 39 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 | 96–203 days per hectare, by hand |
These are the nutrients a lime 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.
