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 3 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Souk Thlata is close to normal, so these dates match the pattern the area usually follows.
Planting after 12 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Souk Thlata
| Rain and temperature | 88% |

For african nightshade in Souk Thlata, the lie of the land is the tightest of the three at 45%. 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.

| When the rains are expected | October 2026 to March 2027 |

| This season's rain | Rain close to usual — plan around about 336 mm falling roughly when it always does |
| 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. |
