Root Management

We find many instances where the above ground symptoms of tree decline are actually caused by problems below ground and out of sight. Training has allowed us to be able to diagnose many of these problems by observation of the tree in question. We use an excavation tool that utilizes compressed air to blow away the soil to expose the roots. The process, called root crown excavation (RCX), allows us to find trunk girdling roots that may be constricting the trunk tissues and inhibiting the transfer of nutrients, water, and photosynthates to and from the tree’s canopy. Careful removal of trunk girdling roots can have a dramatic effect on the tree’s health and survival.

 

Another typical use of the air excavation tool is for the mitigation of soil compaction in the root zones of trees. This radial trenching technique is designed to remove compacted soil over a portion of the root zone. It is then replaced with a lighter soil or compost to create a new area for the roots.

Prior to construction the air tool can be used to open trenches and footers or locate underground utilities that are in close proximity to valuable trees. This enables us to expose, evaluate, and, if necessary, prune significant roots. This technique is an extremely valuable tool to reduce the impact of digging and helps preserve trees.
