[CANUFNET] Materials for base of trees

[Taylor Morris]

Hello Canufnet!

I am currently exploring alternative materials to place around the base of trees that are surrounded by sidewalks/paving. Typically we use crushed rock and compact it in order to minimize tripping hazards. We are interested in finding other options to mitigate some compaction and provide better drainage for the trees. We've experimented with mulch, but have encountered challenges with its longevity, particularly due to heavy rainfall in the Pacific Northwest.

I'm reaching out to inquire if anyone in the community has experience with using pour-in-place rubber or molded rubber as an alternative solution?

Any insights or recommendations on materials or techniques would be greatly appreciated.

Thanks in advance!
