We just planted areas with 70% evergreens, like mugo pines, Japanese hollies, junipers, blue ice cypress; and the remaining 30% with neon spirea, harbor belle nandina, Virginia sweetspire, and viburnums. Our soil is clay and we added top soil. Can I use mushroom soil as mulch, or will it be detrimental to the ph?
I am of the understanding that to change the PH level from 5.5 to 6.5 takes something like 1 1/2 to 2 tons of lime per acer depending on the composition of the soil. So on the basis of this it will take a lot to change the PH level where it will make a great deal of difference. Soils are consantly changing as organic materials break down and are filtered into the ground by water. Most of the plants you are growing will grow in a wide range of soils anyway as will most plants.
I for one don't see why not, as I have mushrooms growing in my yard. I don't know where they come from, but they are different types. They grow mainly in the lower side of our property where water would run off. That area would have had accumulated leaves and grass clippings so there is some good stuff in the soil to be growing them or light conditions.
