Q.Can You Give Tips In Grafting Plants Or Trees?
I have a mango tree which I tried many time to make grafting with same tree but different species but all my tries went unsuccessful, can I use many species in one tree for example my mango tree is (fairchild) type, so can I graft other types of mango like Tommy Atkinson,keitt,kent,Nam Doc Mai etc, and if possible how many type Can I graft in one tree? Thanks for your time.
