When to plant Kale in Hai
Kilimanjaro, United Republic of Tanzania
Known here as sukuma wiki
Rape, covo and kale are the everyday leafy greens of the African plot — the relish in the pot most nights.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 27 Jan 2027 – 16 Feb 2027 opens in 17 weeks | 10 Feb 2027 – 9 Aug 2027 |
| Expected harvest | about 29.2 t/ha | about 50.0 t/ha |
| Harvest | From 27 May 2027 to 15 Aug 2027, depending on the planting date | |
| Ready to harvest | 120–180 days after planting | |
| Work it takes | 100–222 days per hectare, by hand | |
| Rain meets its needs | 85% | |
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 16 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Hai 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 16 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026 season in Hai
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 622 mm |
| This season's rain | Leaning wet — February 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 short crop, and only if timed to it, 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 34% of this area. |
| 34% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 134 growing days · about 610 mm · February to June |
|---|---|
| 17% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 189 growing days · about 760 mm · February to July |
| 9% | enough rain for a long crop, or two in a year; cold for much of the year, with a short planting season 315 growing days · about 1,480 mm · September to July |
| 8% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 306 growing days · about 1,350 mm · September to July |

What it takes to grow kale in Hai
| Planting material | About 60,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 131 kg per hectare |
| Phosphate (P₂O₅) | About 29 kg per hectare |
| Potash (K₂O) | About 175 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 | 100–222 days per hectare, by hand |
These are the nutrients a kale 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.
