Landscape fabric and tree health
This was peeled back (just bark on top) at a client in Nampa who's property was just ten year old. Most of the tree roots were on the surface searching for water and oxygen. The fabric was NOT breathing but the little pores in it were clogged from the organic matter break down. Water was running off so the roots were getting almost none of the irrigation.
I have seen this all over the treasure valley. You need to dig around your trees and pull the fabric back. If this is happening; remove the fabric several feet past the drip line.
You'll find roots growing into the fabric as well, especially small feeder roots. Unfortunately a lot of this will have to be removed but if you don't do it now it will end up killing the tree.
In this case we did airspade work and used the high compressed air to separate the root growth from the fabric and then did trenches to help with the organic matter in the soil.
