Rootstocks and soil types
I have a hard time keeping track of which rootstock appreciates what type of soil. Here in Tx is seems Huey is the most popular one (though is suckers horribly). Where I live we have Houstok black clay. It's rich in nutrients, but on the alkaline side, and tends to become slimy when wet but concrete when dry.
Is there a short list of rootstocks and the types of soil they like?
