When to plant Lablab in Free State
South Africa
Lablab (also called hyacinth bean or dolichos; njahi in Swahili) is one of the toughest beans a smallholder can grow.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 7 Nov 2026 – 7 Dec 2026 opens in 5 weeks | 29 Aug 2026 – 7 Dec 2026 |
| Expected harvest | 1.3–1.5 t/ha | about 2.0 t/ha |
| Harvest | From 15 Feb 2027 to 6 May 2027, depending on the planting date | |
| Ready to harvest | 100–150 days after planting | |
| Work it takes | 75–156 days per hectare, by hand | |
| Rain meets its needs | 66% | |
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 7 Dec 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Free State yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 7 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Free State
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 96% |
For lablab in Free State, rain and temperature is the tightest of the three at 88%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2026/27 season in Free State
| 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 669 mm in a typical farming district |
| Across its districts | From about 438 mm in the driest of 5 districts to about 669 mm in the wettest |
| This season's rain | Leaning dry — 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 +1.7 °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 | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 38% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 440 mm |
|---|---|
| 24% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 91 growing days · about 520 mm · November to April |
| 12% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 138 growing days · about 550 mm · December to May |
| 12% | enough rain for one full main crop; warm, with a cool spell that slows winter growth 191 growing days · about 630 mm · October to May |
| 11% | enough rain for one full main crop; cool for part of the year, so frost sets the planting date 211 growing days · about 660 mm · October to May |

Limited water holds back about 35% of yield here.
What lablab needs to grow here
| Soil it likes | well-drained sand, sandy loam, loam, clay loam or clay soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.0 and 7.5 |
| Spacing | 75 cm between rows, 30 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow lablab in Free State
| Nitrogen (N) | About 48 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 12 kg per hectare |
| Potash (K₂O) | About 17 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 75–156 days per hectare, by hand |
These are the nutrients a lablab 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.
