What grows in Bumba
Mongala, République démocratique du Congo
The 2026 season in Bumba
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,432 mm |
| This season's rain | Rain close to usual — plan around about 1,432 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.1 °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 Divisi would not plant in Bumba
Every crop in the catalogue is scored against this district, not only the ones that work — so the list above is a decision rather than a shortlist. These are the rest, with what ruled each one out.
- Avocado Unsuitable — Temperature
- Beetroot Unsuitable — Temperature
- Cabbage Unsuitable — Temperature
- Chickpea Unsuitable — Temperature
- Enset Unsuitable — Temperature
- Garlic Unsuitable — Temperature
- Niger seed Unsuitable — Temperature
- Passion fruit Unsuitable — Temperature

Divisi scored 74 crops against this district's own ground; 12 came back without a sowing date.
Plan the season, not just check it
The crops and dates above are read at cells spread across Bumba, 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.
Or check your field firstWhat changed in Bumba

Frequently asked questions
What crops grow well in Bumba?
African nightshade, Cashew, Common bean, Cowpea, Cucumber all rate well in Bumba — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant African nightshade in Bumba?
In Bumba the window for African nightshade runs 28 Feb 2026 to 10 Oct 2026.
Is there a farming app that works in Bumba?
Divisi does. It reads Bumba'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 Bumba, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
