What grows in Shiselweni
Shiselweni, Eswatini
The 2026/27 season in Shiselweni
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to April 2027 |
| Rain in a typical year | About 664 mm |
| This season's rain | Leaning dry — January, February, 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 +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 full main crop, warm, with a cool spell that slows winter growth |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 96% of this area. |
| 96% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 221 growing days · about 710 mm · September to May |
|---|---|
| 4% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 205 growing days · about 620 mm · September to April |

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 Shiselweni with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

Plan the season, not just check it
The crops and dates above are read at cells spread across Shiselweni, 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 Shiselweni?
Mango, Avocado, Lime, Finger millet, Lemon all rate well in Shiselweni — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Mango in Shiselweni?
In Shiselweni the window for Mango runs 1 Dec 2026 to 30 Jan 2027.
Is there a farming app that works in Shiselweni?
Divisi does. It reads Shiselweni'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 Shiselweni, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
