We have a few well established peach and apples trees. They were grafted on to hardier root stock for our climate. Recently my wife and I mounted shaving mixed with horse menu re at their base and planted irises and garlic. The mound is higher than the graft mark.
My understanding is when planting it isn't a good idea to have dirt above the graft mark because the scion will root.
Is it OK to have mounded compost/manure above the graft line if the tree is well established or do we need to change it?
