Over the summer I store trimmed branches to use as kindling. Most fruit trees are not as good as pine wood scraps but this summer I pruned my lemon drop mangosteen heavily and the wood (even small branches) is outstanding kindling. It burns fast, hot and unlike most fruit woods instead of going instantly to ash it turns into hot red coal like material which lasts a longer time than any other kindling I have used.
If you have mangosteen and a fireplace or firepit keep your trimmings instead of chucking them out.
