| When to plant | 17 Sep 2026 – 7 Oct 2026 open now | 10 Feb 2027 – 2 Mar 2027 |
| Expected harvest | 3.5–3.8 t/ha | about 12.4 t/ha |
| Harvest | From 15 Jan 2027 to 5 May 2027, depending on the planting date | |

| Rain meets its needs | 84% | |
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 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sigus is close to normal, so these dates match the pattern the area usually follows.
Planting after 7 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Sigus
| When the rains are expected | October 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 487 mm |
| This season's rain | Rain close to usual — plan around about 487 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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, with a cool spell that slows winter growth |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 96% of this area. |
| 96% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 220 growing days · about 510 mm · October to May |
|---|---|
| 4% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 201 growing days · about 600 mm · February to May |

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 Sigus
| Nitrogen (N) | About 38 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 38 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.
