    Weed Killer That Works

    By Ken on 06/20/2020

    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.

Sort Questions
Will Fertilome Weed Out With Crabgrass Killer RTU kill coarse tall fescue?

We have numerous clumps and it seems like it's taking over an area


Fertilome Weed Out With Crabgrass Killer RTU will not kill fescue as it is labeled to be used on both warm and cool season lawns for crabgrass and broadleaf weed control. 

Since tall fescue is a cool season grass type, the best way to eradicate it in a cool season lawn and not damage your lawn is going to be to spot treat using a non selective such as Roundup QuickPro and reseed after 2 weeks.

Can Fertilome Weed Out With Crabgrass Killer RTU and insecticide be sprayed together?

Have permethrin-sfr and tenacity


We do not recommend mixing Fertilome Weed Out With Crabgrass Killer RTU with an insecticide. This product is a ready to use and is used as is.  Also typically not recommended to tank mix the 2 types of products as each contain different properties that could degrade the effectiveness of the active ingredients
