When to plant Grapefruit in Namibia
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 33.9 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 Namibia leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
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 Namibia
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For grapefruit in Namibia, 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 2026/27 season in Namibia
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | December 2026 to April 2027 |
| Rain in a typical year | About 450 mm in a typical farming district |
| Across its districts | From about 12 mm in the driest of 107 districts to about 679 mm in the wettest |
| This season's rain | Leaning dry — January, February and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +2.1 °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 one short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 36% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 108 growing days · about 460 mm · December to April |
|---|---|
| 32% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 120 mm |
| 21% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 190 mm · January to March |
| 6% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 97 growing days · about 420 mm · December to April |

Frost and pest pressure hold back about 20% of yield here.
What grapefruit needs to grow here
| Soil it likes | well-drained loam or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.5 |
| Spacing | 650 cm between rows, 650 cm between plants |
| Feed it most with | nitrogen, potassium, magnesium, zinc and boron |
What it takes to grow grapefruit in Namibia
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 68 kg per hectare |
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 102 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.
