Dead grass redux

Unlikely. I've got several large maples (silver and sugar) and the only surface roots I see are large and woody and would easily be burried for years if I covered them with an inch or two of topsoil. And you'd shorten the trees lifespan, in the process. Those roots are there, at that depth, for a reason. That's where the water, nutrients, and more importantly, oxygen is located. I have seen many species of trees in urban settings that are surrounded by paving almost up to their trunk and they grow very large and appear very healthy. Paving like that is not something I would ever do or recommend, but it's clear evidence that the idea of adding a few additional inches of topsoil under trees will have ZERO effect on oxygen availability to the roots, and a healthy layer of turf grass under a tree will probably do more for water retention and keeping the soil moist and cool in the middle of summer vs having bare soil. |
