Maybe that explains why the Roundup I sprayed a couple weeks ago acted like fertilizer to the clover growing in my gravel/stone. A lot of chemicals are being banned. I learned last month that lawn fertilizer no longer has phosporous included.
A lot of commercial lawn services used a Dupont project this year that has killed all the very mature Spruce or Pine trees in our development. This problem appears to be happening all over the country. I don't know how the got the product on the market without knowing of the potential problems.
