When to plant Ginger in Gichugu
Kirinyaga, 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 | Moderate | |
| When to plant | 7 Sep 2026 – 27 Oct 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 7.8 t/ha | same |
| Harvest | From 5 May 2027 to 23 Aug 2027, depending on the planting date | |
| Ready to harvest | 240–300 days after planting | |
| Work it takes | 130–255 days per hectare, by hand | |
| Rain meets its needs | 63% | |
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 27 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Gichugu 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 27 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Gichugu
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For ginger in Gichugu, the lie of the land is the tightest of the three at 60%. 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 2025 season in Gichugu
| When the rains are expected | December 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 1,977 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 +1.0 °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 | 4 kinds of ground. The season below is the largest that farms — about 47% of this area. |
| 47% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 345 growing days · about 1,610 mm · February to January |
|---|---|
| 16% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 258 growing days · about 1,210 mm · September to July |
| 16% | 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 1,750 mm · January to December |
| 8% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 365 growing days · about 1,780 mm · January to December |

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 Gichugu
| Nitrogen (N) | About 23 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 6 kg per hectare |
| Potash (K₂O) | About 39 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.
