| Harvest | From 12 May 2027 to 19 Aug 2027, depending on the planting date | |

| Rain meets its needs | 92% | |
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 12 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for United Republic of Tanzania 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 21 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in United Republic of Tanzania
| 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 778 mm in a typical farming district |
| Across its districts | From about 425 mm in the driest of 170 districts to about 2,004 mm in the wettest |
| Rainy seasons, district by district | Of 170 districts: one rainy season in 149 and two rainy seasons in 2 |
| 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 +0.9 °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 | 7 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 43% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 199 growing days · about 940 mm · November to May |
|---|---|
| 19% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 214 growing days · about 750 mm · October to May |
| 12% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 153 growing days · about 530 mm · November to April |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 208 growing days · about 960 mm · October to May |
| 4% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 212 growing days · about 670 mm · October to May |
| 4% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 167 growing days · about 560 mm · November to April |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 277 growing days · about 910 mm · September to June |

What it takes to grow garlic in United Republic of Tanzania
| Nitrogen (N) | About 47 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 19 kg per hectare |
| Potash (K₂O) | About 47 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.
