Hi, I didn't have a problem taking off the flesh when eating my longkong ones just be careful not to bite them, these species and alupag are mono, only need one tree to fruit..

How to pack these seeds for long distance? After sprout  will possible?

What about Duku nd longong  Is these need seperate male, female Raul?

Duku, Langsat, and longkong all appear to be the same species or close enough.  They are not individually male and female, a single tree will produce.  Be prepared to wait a long time for production from a seedling of these.
