Quthing, Lesotho
Sunflower is a tall, upright plant — about 1–2 m, higher than your head — that carries one big flower head on top.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 4 Jan 2027 – 13 Jan 2027 opens in 14 weeks | 18 Sep 2026 – 17 Nov 2026 |
| Expected harvest | 1.2–1.4 t/ha | about 0.3 t/ha |
| Harvest | From 4 Apr 2027 to 23 May 2027, depending on the planting date | |
| Ready to harvest | 90–130 days after planting | |
| Work it takes | 74–155 days per hectare, by hand | |
| Rain meets its needs | 72% | |
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 4 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Tosing 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 13 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Tosing
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For sunflower in Tosing, 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 Tosing
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 704 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 +1.8 °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 76% of this area. |
| 76% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 241 growing days · about 740 mm · September to May |
|---|---|
| 14% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 157 growing days · about 620 mm · November to May |
| 7% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 192 growing days · about 660 mm · October to May |
| 3% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 149 growing days · about 570 mm · November to April |

What sunflower needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Rain it needs | About 400–750 mm across the season |
| Spacing | 60 cm between rows, 25 cm between plants |

What it takes to grow sunflower in Tosing
| Planting material | About 50,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 54 kg per hectare |
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 96 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 | 74–155 days per hectare, by hand |
These are the nutrients a sunflower 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.
