I have some trees with very prominent roots, which are getting battered by the folks who mow the lawn. I know, from reading here that I can't just pile mulch or dirt on top of them, but can I build up the area between them a bit to lessen the impact of the mowers? These areas seem to have become more sunken over the years. Thanks, I agree you should mulch the area to 3" deep. This is not the same as adding soil, which should be avoided. The critical factor is that the mulch does not cover the primary trunk flares at the base of the tree. This part of the tree needs to be able to breathe and dry out between waterings. If the flares are already buried, carefully excavate the excess soil until you expose them. If this results in a large pit or bowl around the tree, you may need to add a trench running outward from the downhill side of the hole (be careful not to cut any roots larger than, say 2" in diameter) and line it with gravel and maybe PVC pipe to allow for drainage. The do your best to mulch without re-burying the flares. Good luck, Keith Babberney ISA Certified Arborist #TX-236 |
