Pine mulch. Does it harm fruit trees?
Just removed a 30 year old pine tree, and I have loads of mulch. I have been mulching my newly planted fruit trees (all kinds). Can this cause any harm? The mulch is a mix of chipped bark, limbs, and needles.
While we are on the subject, I'm also using mulch from a California pepper as well, from a separate pile.
My soil PH is currently at 7. I only have 1 foot deep loamy clay topsoil, followed by silty shale, which is hard, but easily breakable with moisture and a shovel. The chunks of shale I remove dissintegrate in the rain in a few weeks.
