Cashew is a tough evergreen tree that lives and bears nuts for 20 years or more.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 24 Mar 2027 – 2 Jun 2027 opens in 25 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.5 t/ha | about 2.0 t/ha |
| Bearing cycle | 60–90 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Work it takes | 57–127 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 7 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Lamu 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 2 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Lamu
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cashew in Lamu, the lie of the land is the tightest of the three at 88%. 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 Lamu

| Across its districts | From about 714 mm in the driest of 2 districts to about 905 mm in the wettest |

What it takes to grow cashew in Lamu
| Planting material | About 156 plants per hectare |
|---|---|
| Nitrogen (N) | About 52 kg per hectare |
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 33 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 | 57–127 days per hectare, by hand |
These are the nutrients a cashew 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.
