When to plant Lemon in Bubanza
Burundi
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) | 26 Sep 2026 – 23 Feb 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 18.5 t/ha | about 37.1 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 4 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Bubanza 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 23 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Bubanza
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For lemon in Bubanza, 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 2026/27 season in Bubanza
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to June 2027 |
| Rain in a typical year | About 973 mm in a typical farming district |
| Across its districts | From about 746 mm in the driest of 5 districts to about 1,408 mm in the wettest |
| This season's rain | Leaning wet — January, February, October, 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 | 7 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |

What it takes to grow lemon in Bubanza
| Planting material | About 240 plants per hectare |
|---|---|
| Nitrogen (N) | About 37 kg per hectare |
| Phosphate (P₂O₅) | About 7 kg per hectare |
| Potash (K₂O) | About 46 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.
