Atsinanana, Madagascar
Avocado (Persea americana) is a big evergreen tree that, once settled, can bear fruit for decades — one of the highest-value crops a smallholder can grow, for fresh eating and for export.

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 Mahanoro is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mahanoro
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For avocado in Mahanoro, 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.
