Question I have a ring of dead grass around each of my Live Oak trees. The trees are no more that 5 years old. Almost everyone on the street and in the neighborhood has the same problem with the same type of tree. It is a young subdivision and was farm land prior to the subdivision being built. The rings are no where else in the lawn, just around the trees on the outer edges of the branches.
Answer I take it that there is a band of dead grass around each tree roughly corresponding to the drip line of the tree. Has this now shown up or has it been in place all these five years? I am thinking that it is related to the material that was used to stabilize the root ball when the trees were planted. Surely there must be some resident who will remember what was done at the time. The long term health of the trees may have been compromised.
