Fruit bushes -- what are they?
I like using cardboard and mulch around most of my fruiting bushes -- blueberries, raspberries and blackberries -- and trees -- apples, pears, peaches, etc.
It's best to keep cardboard/mulch away from the trunk because rodents can hide under and nibble on the bark, but thats a small area to maintain. I did use a few inches of sharp gravel at the base of the weeping cherry tree in the front yard because its too hard to get past the weeping branches, and that works.
Learning never ends because we can share what we've learned. And in sharing our collective experiences, we gain deeper understanding of what we learned.
