When to plant Grapefruit in Wete
Kaskazini Pemba, United Republic of Tanzania
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) | 4 Sep 2026 – 24 Sep 2026 closed for this season | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 22.6 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 | 97% | |
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 24 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Wete 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 24 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Wete
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For grapefruit in Wete, 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 2026 season in Wete
| When the rains are expected | December 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,677 mm |
| 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 +1.1 °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 | 2 kinds of ground. The season below is the largest that farms — about 77% of this area. |
| 77% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 319 growing days · about 1,480 mm · September to August |
|---|---|
| 23% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 329 growing days · about 1,500 mm · December to December |

What it takes to grow grapefruit in Wete
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 45 kg per hectare |
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 68 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.
