When to plant Sweet potato in Lesotho
Sweet potato is a trailing vine you grow from vine cuttings (slips), not from seed and not by planting the root.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Moderate | |
| When to plant | 18 Oct 2026 – 17 Nov 2026 opens in 3 weeks | 8 Oct 2026 – 17 Nov 2026 |
| Expected harvest | about 9.3 t/ha | about 23.9 t/ha |
| Harvest | From 16 Jan 2027 to 16 Apr 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 70–148 days per hectare, by hand | |
| Rain meets its needs | 57% | |
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 17 Nov 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Lesotho yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 17 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Lesotho
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For sweet potato in Lesotho, rain and temperature is the tightest of the three at 76%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2026/27 season in Lesotho
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to May 2027 |
| Rain in a typical year | About 628 mm in a typical farming district |
| Across its districts | From about 572 mm in the driest of 78 districts to about 926 mm in the wettest |
| This season's rain | Leaning dry — January, February, 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 +2.0 °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, with a cool spell that slows winter growth |
| Ground this covers | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 58% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 235 growing days · about 740 mm · September to May |
|---|---|
| 19% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 157 growing days · about 620 mm · November to May |
| 9% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 202 growing days · about 670 mm · October to May |
| 6% | enough rain for one full main crop; cold for much of the year, with a short planting season 232 growing days · about 890 mm · September to April |
| 4% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 152 growing days · about 590 mm · November to May |

Limited water holds back about 45% of yield here.
What sweet potato needs to grow here
| Soil it likes | well-drained sandy, sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 6.5 |
| Rain it needs | About 750–1,000 mm across the season |
| Spacing | 100 cm between rows, 30 cm between plants |
| Feed it most with | potassium and nitrogen |
What it takes to grow sweet potato in Lesotho
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 37 kg per hectare |
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 74 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 | 70–148 days per hectare, by hand |
These are the nutrients a sweet potato 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.
