Here is a site where we have annually root fed 11 Oaks with incredible success. Twice we have inoculated the root systems with Mycorhizzae, a bio-root stimulant. In the in-between years, we fed them with organic fertilizers. The client's testimonial tells the story.

"We built our house in 2005 on a heavily wooded lot with eleven large, mature oaks that our builder had to work around. Knowing the sensitivity of Oaks to soil compaction damage and to the root system, we consulted Graf Tree Care as to what could be done to protect the trees. He recommended using Mycorhizzae to help strengthen the root system and after several seasons use a root feeding. The results speak for themselves. One oak is only inches from our house and the roots were literally chopped in half when they laid the foundation. All of our oaks are thriving, including our "house hugger". Thank you Phil."

The thanks are echoed right back to you John and Sherry!
