| Fit | Favourable |
|---|---|
| When to plant (establish) | 10 Feb 2027 – 9 Aug 2027 opens in 19 weeks |
| Expected harvest | about 24.5 t/ha |
| Work it takes | 91–203 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 2 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Uthukela 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 9 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Uthukela
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For mandarin in Uthukela, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026/27 season in Uthukela
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to April 2027 |
| Rain in a typical year | About 720 mm |
| This season's rain | Leaning dry — January, February, October, 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 +1.6 °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 full main crop, warm, with a cool spell that slows winter growth |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 73% of this area. |
| 73% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 212 growing days · about 750 mm · October to April |
|---|---|
| 18% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 244 growing days · about 890 mm · September to June |
| 5% | enough rain for a long crop, or two in a year; cool for part of the year, so frost sets the planting date 274 growing days · about 950 mm · September to June |
