When to plant Tea in Northern
Zambia
Known here as tiyi
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) | 26 Oct 2026 – 14 Jan 2027 opens in 4 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.5 t/ha | about 3.3 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 5 Nov 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Northern 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 14 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Northern
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 96% |
For tea in Northern, 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 2026/27 season in Northern
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to May 2027 |
| Rain in a typical year | About 1,042 mm in a typical farming district |
| Across its districts | From about 909 mm in the driest of 12 districts to about 1,325 mm in the wettest |
| This season's rain | Leaning wet — January, 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 +1.2 °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 | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 80% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 210 growing days · about 1,170 mm · October to May |
|---|---|
| 13% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 209 growing days · about 1,100 mm · October to May |
| 5% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 174 growing days · about 870 mm · October to April |

Limited water holds back about 55% of yield here.
What tea needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 4.5 and 5.5 |
| Spacing | 120 cm between rows, 60 cm between plants |
| Feed it most with | nitrogen, potassium and zinc |
What it takes to grow tea in Northern
| Planting material | About 12,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 75 kg per hectare |
| Phosphate (P₂O₅) | About 11 kg per hectare |
| Potash (K₂O) | About 38 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.
