When to plant Lemon in Southern Province
Rwanda
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) | 3 Aug 2026 – 31 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 20.3 t/ha | about 30.1 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 15 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Southern Province 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 31 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Southern Province
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For lemon in Southern Province, the lie of the land is the tightest of the three at 30%. 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 2026/27 season in Southern Province
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,040 mm in a typical farming district |
| Across its districts | From about 908 mm in the driest of 8 districts to about 1,284 mm in the wettest |
| This season's rain | Leaning wet — January, February, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.2 °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 | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 65% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 317 growing days · about 1,040 mm · August to July |

What lemon needs to grow here
| Soil it likes | well-drained loam or sandy loam soil |
|---|---|

What it takes to grow lemon in Southern Province
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 41 kg per hectare |
| Phosphate (P₂O₅) | About 8 kg per hectare |
| Potash (K₂O) | About 51 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 | 102–218 days per hectare, by hand |
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.
