When to plant Sweet potato in Maarif
M'Sila, Algeria
Sweet potato is a trailing vine you grow from vine cuttings (slips), not from seed and not by planting the root.
| Fit | Favourable |
|---|---|
| When to plant | 10 Jun 2027 – 19 Jun 2027 opens in 36 weeks |
| Expected harvest | about 17.4 t/ha |
| Harvest | From 8 Sep 2027 to 16 Nov 2027, depending on the planting date |
| Ready to harvest | 90–150 days after planting |
| Work it takes | 70–148 days per hectare, by hand |
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 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Maarif is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
