When to plant Tea in Sironko
Eastern, Uganda
Known here as chai
Tea (Camellia sinensis) is an evergreen highland bush you grow not for one harvest but as a living plucking table — a flat-topped hedge, kept pruned to about waist height, that pushes out soft new shoots again and again for a whole generation.

| Fit | Favourable | |
| When to plant (establish) | 2 Mar 2026 – 18 Sep 2026 closed for this season | 1 Jan 2026 – 31 Dec 2026 |
| Expected harvest | about 3.1 t/ha | same |
| Work it takes | 213–430 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 11 Apr 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Sironko leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 18 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sironko
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For tea in Sironko, 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 season in Sironko
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,128 mm |
| This season's rain | Leaning wet — February, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.4 °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 39% of this area. |
| 39% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 305 growing days · about 1,200 mm · February to December |

What it takes to grow tea in Sironko
| Planting material | About 12,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 155 kg per hectare |
| Phosphate (P₂O₅) | About 23 kg per hectare |
| Potash (K₂O) | About 78 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. |
| Hand work | 213–430 days per hectare, by hand |
These are the nutrients a tea 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.
