Living Mulches for fruit trees?
I have an awful time here at my place with voles/moles. I try to maintain a nice mulched area under my fruit trees to conserve moisture, prevent lawn competition with the trees and to aid in lawn maintenance. Trouble is voles love love love to burrow around under it causing massive destruction to the trees root systems. So bad as to kill young trees. Yes...I've tried to get rid of the voles. Impossible.
I've recently pulled up all mulch and will no longer use it. My question is: Do any of you have use "living mulches" under your trees? I was thinking of Dutch White Clover because of it's low growth habit, nitrogen fixing qualities, and general neat appearance. My lawn is already full of it anyway.
I've been studying this lately and came across this new cultivar of clover called miniclover and another called microclover. It seems like an ideal candidate. I also have some gypsophila seed here that has a growing height of 4-6" that would look very attractive and like the clover, would not require mowing or trimming under the trees. Thoughts, ideas, opinions?
