Best weed killer for lawns with rocks landscaping
The last two weeks the weeds have come out and grown with vengeance all over the lawn between all the rocks.
I need to find something that will kill it all and last. I prefer to have a ready-to-use product rather than a concentrate to mix in a sprayer I would have to buy. The ground is hard and dry here in AZ so not sure if it is wise to water a little first before applying the weed killer. I know Ortho and Roundup are the two big ones many homeowners use. I don't have a huge yard but have weeds coming up all over. I'm sure the landscapers didn't put down a tarp to block the weeks or it was done poorly. Any advice appreciated. |

Ortho ground clear works better for weeds growing in rock beds than the aforementioned brands. In my experience at least.

This. Ortho Groundclear ftw. Get the concentrated version and a $20 sprayer at Home Depot, spray your entire yard with enough to wet the rocks and you’re golden for 6 months.

Ortho is a brand, not a specific product.
It depends what you are trying to kill. Glysophate will kill everything it touches. There are a ton of broadleaf killing products on the market...just make sure the label says that it targets whatever weed(s) you need to kill. If you are targeting a specific grass (not a broadleaf). Things get markedly more difficult and expensive. If you want lasting impact, use the post emergent herbicide now and then hit it with a pre emergent now and again in the fall - it will stop seeds from germinating. |

Do you want a selective herbicide that won't kill grass? Or do you want scorched earth mother****er?
Selective = 2,4-D broad leaf killer sold by Southern Agriculture. buy a pressure sprayer and have a day. READ INSTRUCTIONS TO MIX. A selective herbicide can become non-selective if mixed incorrectly. scorched earth = round up. |

You're probably looking for a sterilizer. We used to use something called Sahara. The name was very fitting. You should be aware that some sterilizers will travel, so any root systems that get to it can have serious issues.
Roundup hasn't killed "everything" for years and will do absolutely nothing for the weeds that will piss you off when they come up few weeks from now. |
