When to plant Pineapple in Garsen
Tana River, Kenya
Known here as nanasi · mananasi
Pineapple is a tough, low-growing plant — a rosette (a circle of stiff, spiny leaves growing out from one central point) about waist-high, carrying one sweet fruit in its heart.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 11 Mar 2027 – 31 Mar 2027 opens in 23 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 46.3 t/ha | about 70.0 t/ha |
| Bearing cycle | 450–730 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 158–335 days per hectare, by hand | |
| Rain meets its needs | 92% | |
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 11 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Garsen 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 31 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Garsen
| 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 680 mm |
| 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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 60% of this area. |
| 60% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 203 growing days · about 720 mm · September to January |
|---|---|
| 19% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 147 growing days · about 580 mm · September to December |
| 14% | 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 620 mm · September to December |
| 3% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 249 growing days · about 950 mm · March to December |
