When to plant Roselle in Djougou
Donga, Benin
Roselle — you may know it as bissap, zobo, karkade or sorrel — is a tall, warm-season hibiscus grown for the fleshy red cups (the calyces) that swell at the base of each flower once the petals drop.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 10 Apr 2027 – 9 Jul 2027 opens in 27 weeks | 22 Mar 2026 – 8 Oct 2026 |
| Expected harvest | about 1.1 t/ha | same |
| Harvest | From 8 Aug 2027 to 5 Jan 2028, depending on the planting date | |
| Ready to harvest | 120–180 days after planting | |
| Work it takes | 85–175 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 20 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Djougou is close to normal, so these dates match the pattern the area usually follows.
Planting after 9 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Djougou
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For roselle in Djougou, 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 2027 season in Djougou
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | April 2027 to November 2027 |
| Rain in a typical year | About 1,076 mm |
| This season's rain | Rain close to usual — plan around about 1,076 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.9 °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 all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

What it takes to grow roselle in Djougou
| Nitrogen (N) | About 44 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 16 kg per hectare |
| Potash (K₂O) | About 61 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 | 85–175 days per hectare, by hand |
These are the nutrients a roselle 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.
