When to plant African nightshade in Sigwe
Shiselweni, Eswatini
African nightshade (Solanum scabrum — mnavu, managu, osuga, nsugga, umsobo) is one of Africa's most-loved traditional leafy vegetables: soft, dark, iron- and vitamin-rich leaves that cook down fast and sell steadily at market.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 25 Dec 2026 – 13 Feb 2027 opens in 12 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 10.8 t/ha | about 17.1 t/ha |
| Harvest | From 23 Feb 2027 to 13 Jun 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 103–191 days per hectare, by hand | |
| Rain meets its needs | 70% | |
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 14 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sigwe leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 13 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sigwe
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 76% |
For african nightshade in Sigwe, 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 Sigwe
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to April 2027 |
| Rain in a typical year | About 726 mm |
| This season's rain | Leaning dry — January, February, October, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +1.3 °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, with a cool spell that slows winter growth |
| Ground this covers | One kind of ground throughout. |

What african nightshade needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |

What it takes to grow african nightshade in Sigwe
| Planting material | About 125,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 43 kg per hectare |
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 54 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 | 103–191 days per hectare, by hand |
These are the nutrients a african nightshade 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.
