When to plant Tea in Oromia
Ethiopia
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.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 18 Apr 2027 – 23 Jul 2027 opens in 28 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 3.2 t/ha | about 3.9 t/ha |
| 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 30 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oromia is close to normal, so these dates match the pattern the area usually follows.
Planting after 23 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Oromia
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For tea in Oromia, the lie of the land is the tightest of the three at 60%. 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 2027 season in Oromia
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | April 2027 to November 2027 |
| Rain in a typical year | About 1,412 mm in a typical farming district |
| Across its districts | From about 455 mm in the driest of 22 districts to about 1,811 mm in the wettest |
| Rainy seasons, district by district | Of 22 districts: one rainy season in 18 and two rainy seasons in 4 |
| This season's rain | Rain close to usual — plan around about 1,412 mm falling roughly when it always does |
| 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 all year, so nothing but rain ends the season |

What it takes to grow tea in Oromia
| Planting material | About 12,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 160 kg per hectare |
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 80 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.
