Why is that you ask??? Either (1.) The tree came to the site too low in it’s container or root ball. (2.) Was planted too low. (3.)Mulch-Man there is a whole lotta mulching going on! mulch that is applied and how it is applied really irks me. I wish I could find some of those slides I have where the mulch is piled up a few feet high around the base of a tree. 7 or 8 inches deep in beds-but I digress.
This has to be one of my greatest pet peeves that I see in today’s landscaping practices-whether it be homeowner or professional. Too much mulch !!!! So lets get that under control. For me-give me some great root flare any day.
