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 Feb 2027 – 22 Mar 2027 opens in 19 weeks |
| Expected harvest | about 22.7 t/ha |
| Harvest | From 11 May 2027 to 19 Aug 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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Malanville is close to normal, so these dates match the pattern the area usually follows.
Planting after 22 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Malanville
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2027 to October 2027 |
| Rain in a typical year | About 770 mm |
| This season's rain | Rain close to usual — plan around about 770 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.3 °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 all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |
