When to plant Arabica coffee in Mwala
Machakos, Kenya
Known here as kahawa
Arabica is the cool-highland coffee — a small evergreen tree kept pruned to about your own height (1.5–2 m) so you can pick standing on the ground.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 Jan 2026 – 1 Jan 2027 open now |
| Expected harvest | about 2.3 t/ha |
| Bearing cycle | 210–270 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. |
| Work it takes | 140–280 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 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Mwala 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 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mwala
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For arabica coffee in Mwala, the lie of the land is the tightest of the three at 60%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.
The 2026/27 season in Mwala
| 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 644 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 | 3 kinds of ground. The season below is the largest that farms — about 85% of this area. |
| 85% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 171 growing days · about 650 mm · October to January |
|---|---|
| 10% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 182 growing days · about 690 mm · October to January |
| 4% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 220 growing days · about 770 mm · October to June |
