When to plant Ginger in Sainte Marie
Analanjirofo, Madagascar
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.

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 10 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sainte Marie is close to normal, so these dates match the pattern the area usually follows.
Planting after 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 110 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. |

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.
