When synthetic landscape fabric is used as a mulch under trees for an extended period of time, it can lead to problems such as root girdling. This can restrict normal root growth, leading to tree decline. Remove synthetic landscape fabric after it has done its job of smothering weeds, or, if you use landscape fabric, look for a biodegradable product that will decay gradually and allow the roots to spread out.
