What grows in Plateaux
Haut-Ogooue, Gabon
The 2026/27 season in Plateaux
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,680 mm |
| This season's rain | Leaning dry — September, October, 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 +0.9 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

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.
What grows in Plateaux with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.
What Divisi would not plant in Plateaux

Plan the season, not just check it
The crops and dates above are read at cells spread across Plateaux, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Plateaux?
African eggplant, African nightshade, Amaranth, Bambara groundnut, Banana all rate well in Plateaux — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant African eggplant in Plateaux?
In Plateaux the window for African eggplant runs 7 Aug 2026 to 4 Apr 2027.
Is there a farming app that works in Plateaux?
Divisi does. It reads Plateaux's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Plateaux, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
