Unlike pesticide-centric plant health care programs, our organic nutrients are healthy for your plants. The nutrients thicken the cell walls to help the plants defend against insect attacks and be as resistant as possible to disease. Pesticides may still be utilized, but only in a targeted, limited fashion. We use pesticides which are low or no toxicity whenever possible.

Our team is ready to serve you!

  • “Ron, I just wanted to say thank you for the the job you did in “re-woodsing” the hill in our backyard. As you can see, the fall colors are spectacular. The Parotia, in particular, is showing yellow, gold and red. And the Spring Grove dogwood is the most brilliant red, and perfectly placed. Just think of what it’ll look like in a few years when the trees start getting larger! We really appreciate your help. Thanks.” -Connie & Karl, Westwood

  • “Ron, my deepest thanks for making time in your busy schedule to transplant the tree my mother gave me many years ago. I recommend your company to all my friends and family. You are truly an honest caring individual with deepest passion for your work. I also want to give a shout out to (Certified) Tree Service for recommending you. I have taken your advice and created a mulch bed of pine bark for the tree. It has taken wonderfully to it’s new location. Thank you and may you have a blessed summer.” -Marcos, Liberty Twp.
  • A rep stopped by and eliminated my concerns. Thank you so much for taking care of this so rapidly. I hear you are all very busy. See you later this spring. Jeff, Mason.
