| Fit | Favourable | |
| When to plant | 27 Oct 2026 – 16 Dec 2026 opens in 4 weeks | 20 Jul 2026 – 7 Dec 2026 |
| Expected harvest | about 27.8 t/ha | about 61.4 t/ha |
| Harvest | From 25 Jan 2027 to 15 May 2027, depending on the planting date | |

| Work it takes | 81–160 days per hectare, by hand | |
| Rain meets its needs | 76% | |
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 6 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Umzinyathi 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 16 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.

| The soil | 76% |
| The lie of the land | 88% |

The 2026/27 season in Umzinyathi
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to April 2027 |
| Rain in a typical year | About 746 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 +1.4 °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 91% of this area. |
| 91% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 221 growing days · about 750 mm · September to May |
|---|---|
| 4% | 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 June |
| 3% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 239 growing days · about 820 mm · September to May |

Limited water holds back about 25% of yield here.

What it takes to grow tomato in Umzinyathi
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 72 kg per hectare |
| Phosphate (P₂O₅) | About 19 kg per hectare |
| Potash (K₂O) | About 103 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. |

These are the nutrients a tomato 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.
