When to plant Pineapple in Siaya
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) | 2 Feb 2027 – 22 Feb 2027 opens in 18 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 55.0 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-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 22 Feb 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Siaya yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 22 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2025/26 season in Siaya
| When the rains are expected | February 2025 to January 2026 |
|---|---|
| Rain in a typical year | About 1,156 mm in a typical farming district |
| Across its districts | From about 760 mm in the driest of 6 districts to about 1,596 mm in the wettest |
| Rainy seasons, district by district | Of 6 districts: one rainy season in 1 and two rainy seasons in 1 |
| This season's rain | Leaning wet — January, February, 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 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. |
| 46% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 360 growing days · about 1,470 mm · January to January |
|---|---|
| 37% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 210 growing days · about 780 mm · February to June |
| 8% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 234 growing days · about 890 mm · February to January |
| 4% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 213 growing days · about 800 mm · February to June |
| 3% | 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 1,350 mm · February to January |

What it takes to grow pineapple in Siaya
| Planting material | About 55,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 192 kg per hectare |
| Phosphate (P₂O₅) | About 41 kg per hectare |
| Potash (K₂O) | About 605 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. |

These are the nutrients a pineapple 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.
