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 23 Aug 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Idjwi yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 3 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Idjwi
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,032 mm |
| This season's rain | Leaning wet — January, February, October, November and 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 +1.2 °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 | 2 kinds of ground. The season below is the largest that farms — about 72% of this area. |
| 72% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 334 growing days · about 1,100 mm · August to July |
|---|---|
| 25% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 364 growing days · about 1,260 mm · January to December |

What it takes to grow garlic in Idjwi
| Nitrogen (N) | About 100 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 40 kg per hectare |
| Potash (K₂O) | About 100 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 | 123–248 days per hectare, by hand |
These are the nutrients a garlic 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.
