When to plant Tea in Mareko Special
Central Ethiopia, 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.

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 23 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mareko Special is close to normal, so these dates match the pattern the area usually follows.
Planting after 6 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mareko Special
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For tea in Mareko Special, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2027 season in Mareko Special
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to October 2027 |
| Rain in a typical year | About 896 mm |
| This season's rain | Rain close to usual — plan around about 896 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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 |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 93% of this area. |
| 93% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 238 growing days · about 910 mm · March to October |
|---|---|
| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 226 growing days · about 830 mm · March to October |

| Planting material | About 12,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 115 kg per hectare |
| Phosphate (P₂O₅) | About 17 kg per hectare |
| Potash (K₂O) | About 57 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 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.
