Tree roots in vegetable garden
I have a couple large oaks and ash trees near the veggie garden. (I wish I could take them down, but that's not an option.) They are not shading the garden, but I'm concerned about trees siphoning off nutrients.
I've tried to trim whatever tree roots I find extending into the garden. I've dug down ~20" along the garden edge, cut off and pulled up anything that looked a tree root. I plan to do it again this spring as soon as soil can be worked.
Is there anything else I can do to minimize adverse effect of trees on the veggies?
