Our property was over run with many weeds. We had it landscaped and got rid of most of the weeds however we still had wild morning glory's. i sprayed them with other weed killing products but it didn't do any good. They kept spreading. They have a very long root system.My wife went to a garden center and the owner recommended Fertilome weed killer. She purchased the product and it worked great but like I said we had a lot of wild morning glory's so I went online and found the same product for less money than I paid at the garden center so I bought two more bottles. They are mostly under control now but when they pop up from time to time I have something that will work.
