Hi, we don't do any hand pollinating of cherapu. The pollinators are small stingless bees that also pollinate my salak, among other things. There are a few different species of these bees. They make a medicinal honey that can be harvested in small quantities if you keep them in small boxes, bamboo sections, or ceramics.
We are working on establishing several hives but have been able to rely on natural hives for pollinating so far.
