When to plant Lemon in Rungwe
Mbeya, United Republic of Tanzania
Known here as limau · ndimu
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) | 6 Oct 2026 – 5 Mar 2027 opens in 1 week | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 23.2 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 4 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Rungwe 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 5 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rungwe
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For lemon in Rungwe, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Rungwe
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 1,080 mm |
| 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 +1.1 °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 37% of this area. |
| 37% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 256 growing days · about 1,260 mm · October to July |

| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 230 growing days · about 1,130 mm · October to June |

What it takes to grow lemon in Rungwe

|---|---|
| Nitrogen (N) | About 46 kg per hectare |
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 58 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. |

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.
