When to plant Mandarin in Kasese
Western, Uganda
Known here as chenza
The mandarin (also called tangerine or naartjie) is the hardiest and easiest-to-peel of the citrus trees — a small, spreading evergreen that lives and bears fruit for decades.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 10 Aug 2026 – 8 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 16.4 t/ha | about 19.1 t/ha |
| Work it takes | 91–203 days per hectare, by hand | |
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 21 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kasese is close to normal, so these dates match the pattern the area usually follows.
Planting after 8 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kasese
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For mandarin in Kasese, the lie of the land is the tightest of the three at 88%. 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 2025 season in Kasese
| When the rains are expected | January 2025 to January 2025 |
|---|---|
| Rain in a typical year | About 1,274 mm |
| This season's rain | Rain close to usual — plan around about 1,274 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 | 4 kinds of ground. The season below is the largest that farms — about 27% of this area. |
| 27% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 335 growing days · about 1,000 mm · February to January |
|---|---|
| 20% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 259 growing days · about 760 mm · August to January |
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 1,330 mm · January to December |

What it takes to grow mandarin in Kasese
| Planting material | About 340 plants per hectare |
|---|---|
| Nitrogen (N) | About 33 kg per hectare |
| Phosphate (P₂O₅) | About 7 kg per hectare |
| Potash (K₂O) | About 41 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |

These are the nutrients a mandarin crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
