This week we rented a root pruner to help the turf around trees compete for water and nutrients with tree roots. Here is what the machine looks like.
There are two blades underneath about 8 inches apart. The depth is set to about 7 inches which is where most, if not all, our turf roots are located. We go just inside the drip line of the trees.
The end product looks like this.
Very little disruption to the surface, yet many benefits for the turf!
