I’m taking a seedling (mango grown from seed) and grafting on really great tasting budwood so that the grated wood begins to flush out new growth. Then I cut off the other stem from the seedling and that’s how a lot of people graft good varieties. Much cheaper than buying a whole good mango tree. Something I must mention: mangos are not ‘true to seed’. This mean that even if you have the seed of a really delicious variety, it’s not guaranteed that the tree from the seed will produce mangos that taste as good as the mango whose seed you planted. This is why so many people graft.
