Mostaganem, Algeria
Swiss chard — muriwo, mchicha, silverbeet, spinach beet — is the dependable 'spinach' of African markets and home gardens, though it is not true spinach.

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 15 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sour is close to normal, so these dates match the pattern the area usually follows.
Planting after 14 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Sour
| When the rains are expected | October 2026 to March 2027 |
|---|---|
| Rain in a typical year | About 364 mm |
| This season's rain | Rain close to usual — plan around about 364 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.0 °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 short crop, and only if timed to it, warm, with a cool spell that slows winter growth |
| Ground this covers | One kind of ground throughout. |

|---|---|
| Nitrogen (N) | About 106 kg per hectare |
