When to plant Amaranth in Cape Winelands
Western Cape, South Africa
Known here as imbuya · misbredie
Amaranth (Amaranthus spp.) is a fast, heat-loving plant that gives you two harvests from one crop — tender leaves and tiny grain.
| Fit | Moderate |
|---|---|
| When to plant | 8 Oct 2026 – 17 Nov 2026 opens in 1 week |
| Expected harvest | about 10.2 t/ha |
| Harvest | From 7 Nov 2026 to 16 Apr 2027, depending on the planting date |
| Ready to harvest | 30–150 days after planting |
| Work it takes | 78–163 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 28 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Cape Winelands is close to normal, so these dates match the pattern the area usually follows.
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 Cape Winelands
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 30% |
For amaranth in Cape Winelands, the lie of the land is the tightest of the three at 30%. 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 Cape Winelands
| When the rains are expected | April 2026 to September 2026 |
|---|---|
| Rain in a typical year | About 436 mm |
| This season's rain | Rain close to usual — plan around about 436 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.6 °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 31% of this area. |
| 39% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 200 mm |
|---|---|
| 31% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 146 growing days · about 390 mm · April to September |
| 16% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 200 growing days · about 650 mm · April to October |
| 6% | enough rain for one short crop, and only if timed to it; cool for part of the year, so frost sets the planting date 147 growing days · about 390 mm · April to September |

Sloping ground holds back about 65% of yield here.
What amaranth needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.0 |
| Spacing | 10 cm between rows, 10 cm between plants |
| Feed it most with | nitrogen, phosphorus and potassium |
What it takes to grow amaranth in Cape Winelands
| Nitrogen (N) | About 41 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 51 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 | 78–163 days per hectare, by hand |
These are the nutrients a amaranth 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.
