When to plant Sweet potato in Eden
Western Cape, South Africa
Known here as ubhatata · patat
Sweet potato is a trailing vine you grow from vine cuttings (slips), not from seed and not by planting the root.
| Fit | Favourable |
|---|---|
| When to plant | 28 Oct 2026 – 7 Dec 2026 opens in 4 weeks |
| Expected harvest | about 33.2 t/ha |
| Harvest | From 26 Jan 2027 to 6 May 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-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.
This season's rainfall outlook for Eden is close to normal, so these dates match the pattern the area usually follows.
Planting after 7 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Eden
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For sweet potato in Eden, the lie of the land is the tightest of the three at 76%. 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 season in Eden
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | April 2026 to September 2026 |
| Rain in a typical year | About 413 mm |
| This season's rain | Rain close to usual — plan around about 413 mm falling roughly when it always does |
| 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 short crop, and only if timed to it, warm, with a cool spell that slows winter growth |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 26% of this area. |
| 48% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 340 mm |
|---|---|
| 26% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 130 growing days · about 430 mm · April to September |
| 9% | too dry for rain-fed cropping without irrigation; cool for part of the year, so frost sets the planting date no rain-fed season · about 430 mm |
| 7% | enough rain for a long crop, or two in a year; warm, with a cool spell that slows winter growth 304 growing days · about 670 mm · January to January |

What it takes to grow sweet potato in Eden
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 133 kg per hectare |
| Phosphate (P₂O₅) | About 50 kg per hectare |
| Potash (K₂O) | About 266 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.
