When to plant Irish potato in Boudria Beni Yadjis

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 17 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Boudria Beni Yadjis 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 28 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Boudria Beni Yadjis
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For irish potato in Boudria Beni Yadjis, 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.
The 2026/27 season in Boudria Beni Yadjis
| When the rains are expected | September 2026 to May 2027 |
|---|---|
| Rain in a typical year | About 925 mm |
| This season's rain | Leaning dry — January, February, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| 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 full main crop, warm, with a cool spell that slows winter growth |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 67% of this area. |
