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 2 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Eastern Cape is close to normal, so these dates match the pattern the area usually follows.
Planting after 27 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Eastern Cape
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For swiss chard in Eastern Cape, the lie of the land is the tightest of the three at 88%. 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 Eastern Cape
| When the rains are expected | May 2026 to May 2026 |
|---|---|
| Rain in a typical year | About 633 mm in a typical farming district |
| Across its districts | From about 534 mm in the driest of 8 districts to about 879 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 633 mm falling roughly when it always does |
| What that supports | enough rain for a long crop, or two in a year, warm, with a cool spell that slows winter growth |
| Ground this covers | 7 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 35% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 350 mm |
|---|---|
| 17% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 231 growing days · about 690 mm · September to May |
| 8% | enough rain for a long crop, or two in a year; warm, with a cool spell that slows winter growth 333 growing days · about 840 mm · July to July |
| 8% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 118 growing days · about 540 mm · December to April |
| 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 125 growing days · about 550 mm · December to May |
| 5% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 218 growing days · about 700 mm · October to May |
| 4% | enough rain for a long crop, or two in a year; warm, with a cool spell that slows winter growth 281 growing days · about 890 mm · August to July |

What it takes to grow swiss chard in Eastern Cape
| Planting material | About 200,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 71 kg per hectare |
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 122 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 | 73–145 days per hectare, by hand |
These are the nutrients a swiss chard 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.
