When to plant Lemon in Kailahun
Eastern, Sierra Leone
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) | 1 Feb 2026 – 27 Sep 2026 closed for this season | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 17.5 t/ha | about 24.8 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 1 Mar 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Kailahun yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 27 Sep 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kailahun
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For lemon in Kailahun, the lie of the land is the tightest of the three at 60%. 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 Kailahun
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 2,436 mm |
| This season's rain | Rain close to usual — plan around about 2,436 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.0 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 97% of this area. |
| 97% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 315 growing days · about 2,510 mm · February to December |

What it takes to grow lemon in Kailahun

|---|---|
| Nitrogen (N) | About 35 kg per hectare |
