| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Moderate | |
| When to plant | 21 Aug 2026 – 30 Sep 2026 closed for this season | 1 Jan 2027 – 31 Jul 2027 |
| Expected harvest | about 2.9 t/ha | same |
| Harvest | From 19 Dec 2026 to 28 Apr 2027, depending on the planting date | |
| Ready to harvest | 120–210 days after planting | |
| Work it takes | 123–248 days per hectare, by hand | |
| Rain meets its needs | 90% | |
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 Sep 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Isingiro yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 30 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Isingiro
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For garlic in Isingiro, the lie of the land is the tightest of the three at 30%. 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 2026/27 season in Isingiro
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | August 2026 to May 2027 |
| Rain in a typical year | About 639 mm |
| This season's rain | Leaning wet — January, February, 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 one full main crop, 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 37% of this area. |
| 37% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 258 growing days · about 650 mm · August to May |
|---|---|
| 26% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 277 growing days · about 690 mm · August to June |
| 21% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 249 growing days · about 670 mm · August to January |
| 8% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 290 growing days · about 720 mm · August to June |

What garlic needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.5 and 7.5 |
| Spacing | 30 cm between rows, 10 cm between plants |

What it takes to grow garlic in Isingiro
| Nitrogen (N) | About 29 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 12 kg per hectare |
| Potash (K₂O) | About 29 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.
