When to plant Irish potato in Afigya Kwabre South

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 1 Jul 2027. That is the point in the window where the rains are most reliably established.

This season's rainfall outlook for Afigya Kwabre South leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.

Planting after 10 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

Rain in a typical year	About 1,290 mm
