How do I expand my street tree's tree pit? What is the city policy & what contractors would I use?
Dear Gardener: To get good advice on what to do about your tree lifting the concrete sidewalk, go to PHS Tree Tenders on line. Once at that site, go to Tree Tenders Maps. When there go to "Find Tree Tender" near your area. If you contact that person, they will be able to advise you on the best way to handle the problem.
