When to plant Roselle in Come
Mono, 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 | 13 Mar 2027 – 21 Jun 2027 opens in 23 weeks | 10 Feb 2026 – 17 Nov 2026 |
| Expected harvest | about 1.2 t/ha | same |
| Harvest | From 11 Jul 2027 to 18 Dec 2027, 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 23 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Come 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 21 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Come

|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For roselle in Come, the lie of the land is the tightest of the three at 88%. 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.

| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 951 mm |
| This season's rain | Leaning dry — September and October 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. |

|---|---|
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 66 kg per hectare |
