Q.Ground cover ivy
A bobcat drove over the backyard ivy several times and there is now none left on the top of the ground. I have heard that very little of anything can kill ivy except for specific spraying several times to actually kill it….the roots underneath will regenerate and in the spring new growth will appear. Is this true?
You certainly could see loss of the plant. The heavy compaction of the soil can make it quite difficult for the roots to breath.
You will likely need to wait and see.
