Awesome product

This product works lights out. I mixed it as specified and added some dishwashing soap to it and sprayed on a hot day. Within 1 1/2 weeks the weeds were dead and lasted for a good two months.

Anyone know if this stuff has a shelf life??

9 years ago

I have been using it for 2-3 years now and I sprayed 4-3 and the weeds are still not dead. I mix mine 3-4 times stronger than what calls for. Never had this issue before now. I'm thinking I got last years and its old or they changed the formula. Any input is greatly appreciated!

I like this brand of grass and weed killer because it is less expensive then other brands (if you know who I am talking about). It takes a little longer to do it's job, but it gets the job done just the same. Good Stuff!
