FD2B Talk Radio Insight of the Night: Mark Chisholm

Many of you may know that “girdling” may cause a tree to fail over time. Girdling occurs when a tree root wraps itself around the trunk of the tree, literally choking it to death. The typical cause of girdling, according to Mark Chisholm of Aspen Tree Expert Co., is too much organic material, such as topsoil and/or mulch, covering the root flair of the tree.

This can occur naturally, but in the suburban landscape it's Green Industry professionals that often cause the problem. This is due to the homeowner’s addiction to mulch and our own annual spring process of over mulching, which creates what's commonly referred to as mulch “volcanoes.”

Although improper planting techniques and “mulch madness” are part of the problem, the plants that you, the landscape contractor, purchase from growers and re-wholesalers are often already in distress. As Chisholm points out, the trees may be planted too low in the container or when they're balled and burlapped.

As I read your blog I realized that I want new landscape for my home. I never knew how to start it. This blog has given me inspiration to change the outside of my house.
