Is there any specific direction to achieving this?

Well I went ahead and did this experimental planting of a cogshall and pickering. Pickering on the left and Cogshall on the right planted north and south. They are both extremely healthy and the pickering is already flushing new growth. Now we watch and wait!!!!

Hey Jason, yes they are both dwarf trees (6-8ft) and produce at a smaller size. More like a mango bush. I purposely did it with a smaller size variety so that way I don't have to worry about two huge mango varieties trying to kill each other. And the fruits are easy picking! One thing I would like to know is if I have to fertilize double so that both trees get enough vitamins?

Nice healthy looking little trees, Daniel.

Thanks writersblock!
