Hello, I was given this manilla mango tree from my neighbor the other day and would like to graft better varities onto it. It's about 6ft tall. Can someone PLEASE provide some advice, suggestions, comments, pro-tips, etc. on how to go about grafting this tree? Is this the right time of year to graft mango? Should I leave the tree the height it is now? What part of the tree should I graft onto? Basically, what would you do if this was your tree? I plan on putting it in the ground asap. All comments are GREATLY appreciated. Thank you.
