I have a flower bed in tree box—mostly perennials, although I add annuals yearly. When I got ready to add annuals earlier this month, I noticed an unknown substance in tree box. When I got ready to add garden soil and Leaf Gro to existing soil, I noticed a foreign substance in the bed. I kept trying to remove it, since it was clear that the substance would not support plant growth. I called someone to remove the substance for pay. He and I agreed that nothing would grow in that unknown mixture. I’d like to bring some of the substance to a plant clinic for identification. Photos may not show problem clearly. Darker areas indicate places where I put garden soil/LeafGro mix before I fully realized the amount of foreign substance. If appropriate, I need to know location and time of plant clinics in Silver Spring. I used to go to one at Farmers Market. Thank you.

We had someone reach out to us at Tollgate with questions on how to combat crabgrass, as well as best maintenance/ premeditative procedures for their crab tree, Japanese maple, and silver maple. They were seeking someone to come out to assess best approaches, and are looking for potential recommendations of a company that is certified to do so.
