When to plant Garlic in Tanganyika
République démocratique du Congo
Known here as kitunguu saumu · kitunguu thomu · ail
Garlic (Allium sativum) is grown for its compound bulb — the head that splits into the cloves you cook with.
| Fit | Moderate |
|---|---|
| When to plant | 22 Mar 2027 – 10 Jun 2027 opens in 25 weeks |
| Expected harvest | about 6.1 t/ha |
| Harvest | From 20 Jul 2027 to 6 Jan 2028, depending on the planting date |
| Ready to harvest | 120–210 days after planting |
| Work it takes | 123–248 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 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Tanganyika 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 10 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Tanganyika
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 30% |
For garlic in Tanganyika, 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 Tanganyika
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to May 2027 |
| Rain in a typical year | About 930 mm in a typical farming district |
| Across its districts | From about 912 mm in the driest of 6 districts to about 1,134 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 +1.1 °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 one typical farming district's, not a figure for the whole of this area. |
| 87% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 236 growing days · about 980 mm · September to May |
|---|---|
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 221 growing days · about 1,040 mm · October to May |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 271 growing days · about 1,140 mm · August to May |
| 3% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 173 growing days · about 780 mm · October to April |

Sloping ground holds back about 65% of yield here.
What garlic needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.5 and 7.5 |
| Spacing | 30 cm between rows, 10 cm between plants |
| Feed it most with | sulphur, nitrogen and potassium |
What it takes to grow garlic in Tanganyika
| Nitrogen (N) | About 61 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 61 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 | 123–248 days per hectare, by hand |
These are the nutrients a garlic 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.
