When to plant Tea in Lalangina
Haute Matsiatra, Madagascar
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.

| When to plant (establish) | 28 Oct 2026 – 2 Mar 2027 opens in 4 weeks | 20 Jul 2026 – 30 Jun 2027 |

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 1 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Lalangina is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Lalangina
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 45% |
For tea in Lalangina, 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 Lalangina
| When the rains are expected | September 2026 to September 2026 |
|---|---|
| Rain in a typical year | About 1,452 mm |
| This season's rain | Rain close to usual — plan around about 1,452 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. |

|---|---|
| Nitrogen (N) | About 145 kg per hectare |

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.
