When to plant Ginger in Tarbaj
Wajir, Kenya
Known here as tangawizi
Ginger is a leafy, reed-like plant grown for the knobbly, spicy rhizome — the 'root' — that swells just under the soil and is sold fresh or dried.
| Fit | Favourable |
|---|---|
| When to plant | 22 Mar 2027 – 11 Apr 2027 opens in 25 weeks |
| Expected harvest | about 30.0 t/ha |
| Harvest | From 17 Nov 2027 to 5 Feb 2028, depending on the planting date |
| Ready to harvest | 240–300 days after planting |
| Work it takes | 130–255 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 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Tarbaj 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 11 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Tarbaj
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For ginger in Tarbaj, the lie of the land is the tightest of the three at 88%. 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 season in Tarbaj
| Rain in a typical year | About 327 mm |
|---|---|
| This season's rain | Leaning wet — make sure water can drain off the field. |
| 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 | One kind of ground throughout. |

Frost and pest pressure hold back about 15% of yield here.
What ginger needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.5 |
| Spacing | 25 cm between rows, 22 cm between plants |
| Feed it most with | potassium and nitrogen |
What it takes to grow ginger in Tarbaj
| Nitrogen (N) | About 90 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 22 kg per hectare |
| Potash (K₂O) | About 150 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 | 130–255 days per hectare, by hand |
These are the nutrients a ginger 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.
