I found a different video from a Mango and Avocado grower who says he typically grafts in a branch of a tree with good fruit behavior onto a newly sprouted mango plant. He says letting an ungrafted plant grow to maturity will produce a tree, but will probably not produce a good crop of fruit, due to the variability of DNA. https://m.youtube.com/watch?v=Q2czF7QBxPs https://m.youtube.com/watch?v=Q2czF7QBxPs Made me wonder if that’s why industrial produce doesn’t taste as good as natural. Could removing genetic diversity in fruit cause mutations to creep in?
