When to plant Grapefruit in Quinara
Guinea-Bissau
Grapefruit (Citrus paradisi) is a big, dense evergreen citrus tree you plant once and pick from for decades.
| Fit | Favourable |
|---|---|
| When to plant (establish) | 21 Jan 2026 – 1 Jan 2027 open now |
| Expected harvest | 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-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 rainfall outlook for Quinara is close to normal, so these dates match the pattern the area usually follows.
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 Quinara
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For grapefruit in Quinara, the lie of the land is the tightest of the three at 76%. 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 season in Quinara
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2026 to November 2026 |
| Rain in a typical year | About 1,945 mm in a typical farming district |
| Across its districts | From about 1,658 mm in the driest of 4 districts to about 1,945 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 1,945 mm falling roughly when it always does |
| 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 | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 93% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 1,920 mm · May to November |
|---|---|
| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 185 growing days · about 2,010 mm · May to November |

| Soil it likes | well-drained loam or sandy loam soil |
|---|---|

What it takes to grow grapefruit in Quinara
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 80 kg per hectare |
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 120 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.
