Hello all! I am new here at Dave's and I have a question about fertilizer. One of my friends had a landscaper plant some trees in her back yard and he used a product called "Roots". Have any of you heard of this product? I did a Google search on it to no avail. The landscaper used this product under the trees on the grass he planted. This grass has grown awesome! Unfortunately the landscaper is long gone, or I would ask him.
