The harvest is timed according to the ripeness of the seed. The wet red fleshy calyces are harvested after the flower has dropped but before the seed pod has dried and opened. All harvesting is done by hand. Special care must be taken during harvesting operation to avoid contamination by extraneous material. At no time should the calyx come in contact with the ground or other dirt surfaces. Clean bags or containers should be used to transport from the field to the drying location.
Only ripe calyces are harvested with clippers leaving the stalks and immature calyces to ripen in the field. The field is harvested approximately every ten days until the end of the growing season. The calyx is separated from the seed pod by hand, or by pushing a sharp edged metal tool through the fleshy tissue of the calyx separating it from the seed pod.
A clean sheet of plastic placed on the ground can also be used with the hibiscus spread thinly on top. Spreading the calyces on screens or frames would improve ventilation further and reduce drying time. Such frames could also be stacked or hung in a well ventilated building. Drying the calyces in forced air dryers would be costly and is rarely done. If heated drying methods are used, care must be taken so that the temperature does not exceed 43oC.
The hibiscus after drying is hand cleaned and shifted to export standards.
