Is there a chemical (been trying to avoid that but at this point I don't care anymore) that I can use that won't harm the tree/bushes but will kill weed growth?

Or do I just keep pulling hoping for the day when there will be no more weeds?

Any other suggestions?

Thank you.

Preen and roundup have been with me for years. Works great!
