When to plant Grapefruit in Kisumu
Kenya
Known here as balungi
Grapefruit (Citrus paradisi) is a big, dense evergreen citrus tree you plant once and pick from for decades.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 22 Mar 2026 – 2 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 19.0–21.0 t/ha | about 40.0 t/ha |
| Bearing cycle | 360–420 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 74–148 days per hectare, by hand | |
| Rain meets its needs | 96% | |
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 2 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Kisumu 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 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kisumu
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 45% |
For grapefruit in Kisumu, the lie of the land is the tightest of the three at 45%. 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 Kisumu
| When the rains are expected | February 2026 to January 2027 |
|---|---|
| Rain in a typical year | About 1,160 mm in a typical farming district |
| Across its districts | From about 972 mm in the driest of 7 districts to about 1,225 mm in the wettest |
| 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 | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 82% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 323 growing days · about 1,030 mm · February to January |
|---|---|
| 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 1,320 mm · December to December |
| 7% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 327 growing days · about 1,060 mm · February to January |

What it takes to grow grapefruit in Kisumu
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 41 kg per hectare |
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 62 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 | 74–148 days per hectare, by hand |
These are the nutrients a grapefruit 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.
