| When to plant (establish) | 6 Aug 2027 – 26 Aug 2027 opens in 44 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 15.5–18.5 t/ha | about 0.2 t/ha |
| Bearing cycle | 210–360 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |

| Rain meets its needs | 79% | |
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 26 Aug 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sisonke 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 26 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sisonke
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For sweet orange in Sisonke, the lie of the land is the tightest of the three at 45%. 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 2026/27 season in Sisonke
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to June 2027 |
| Rain in a typical year | About 971 mm |
| 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 +1.5 °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, cool for part of the year, so frost sets the planting date |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 54% of this area. |
| 54% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 246 growing days · about 880 mm · September to May |
|---|---|
| 37% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 233 growing days · about 820 mm · September to May |
| 5% | enough rain for a long crop, or two in a year; warm, with a cool spell that slows winter growth 272 growing days · about 860 mm · August to July |
| 4% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 270 growing days · about 960 mm · September to June |
