Have got some 1 year old 'yung chit' or maprang nam saplings. have been told that the fruit is quite sparse on this tree and wonder whether anyone else has grown them and stimulated fruit bearing levels?

You see them all around Samui, no one even bothers to pick them, they fall on the ground and rot!

An Ozzy friend suggested that they would make good jam, but I really don't think the locals would be into jam making!

I guess too small and tedious to eat?

Unless you have multiple roots on your trees you should not expect a significant amount of fruit for several years, We have an older tree yielding 2,000 baht each year, but have younger trees not doing very well after several years. Btw Mariam plum.

The maprang is not rare, in Nakhon Nayok there are big orchards of them. In BKK they cost like 150 baht a kg and very nice fruits although a bit small.

If you want to grow them then better buy a grafted tree.

I have 2 tree's the bigger one has good fruit and very delicious, we wrap them in paper when they get to a certain size, the other tree no fruit yet.

I read it is possible to graft maprang on mango rootstock, i tried it but it failed. I will try it again just to impress my neighbours, maprangs hanging on my mangotree would be great.

Easier to eat than mango as no peeling required.I love them,Some are sweeter varieties than others.i know three thai families that grow them between 5-20 trees each.As most are friends I get given loads of seconds(mostly marked skins) for free.The top grade ones fetch good money.They are the ones that are rapped in paper.
