When to plant Lemon in West Arsi
Oromia, Ethiopia
The lemon (Citrus limon) is a citrus tree, not a yearly crop — you plant it once and it can crop for decades, flowering and fruiting almost all year round.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 10 Feb 2026 – 8 Oct 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 23.1 t/ha | about 40.0 t/ha |
| Work it takes | 102–218 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 22 Mar 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for West Arsi is close to normal, so these dates match the pattern the area usually follows.
Planting after 8 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in West Arsi
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For lemon in West Arsi, 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 2025 season in West Arsi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2025 to October 2025 |
| Rain in a typical year | About 680 mm |
| This season's rain | Rain close to usual — plan around about 680 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 | 4 kinds of ground. The season below is the largest that farms — about 27% of this area. |
| 27% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 236 growing days · about 840 mm · March to October |

| 25% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 316 growing days · about 1,140 mm · February to December |

|---|---|
| Nitrogen (N) | About 46 kg per hectare |
| Phosphate (P₂O₅) | About 9 kg per hectare |

These are the nutrients a lemon 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.
