Got 4 more trees in the ground. Thought I would share my process. First I dig rather oversized hole for a special concoction I'm going to mix in the hole.
Then the first thing I do is put a layer of oak leaves in the bottom of the hole. Because Oak leaves makes the soil acidic which is what I want anyway.
Then I dump in humus, peat moss, perlite and a tree shrub soil I got it Lowe's which has some organic material in the dirt.
I take a hoe and mix it all in the hole. I also layer hay into the soil as I'm filling up the sides around the plant. Then top the whole area off with hay. they start growing like mad and that environment
