We had a neighbor who just use round up once, then re-sodded. In a year, he had a yard full of weeds again.
So many people do not know a thing about weed killers. Why would anyone expect RoundUp to keep on working over a whole year? It only works on the weeds that it is sprayed on, by killing the growing tips. You do not want it to keep working weeks later or it would kill your newly planted/sodded lawn. And what the heck is a root killer? Do you want to kill all of your subsequent plantings?

Good weed killers have a known way of working and must be used in harmony with that. It is all biology and biochemistry. Not a mysterious miracle that does just what you can imagine in a perfect world. If it was, and with people imagining different things, it would make no sense.

Ask a well trained and experienced herbicide expert if you need advice.

Sorry if I steered anyone wrong. It does nothing to crab grass at my place...nothing.

A story...my neighbor said first day...'Don't try to grow a lawn there...they
put manure there once and nothing will ever grow'.
Well, 17 years later, or more since they did this,
I do get the occasional weed between the flag stone.

If you just want to kill plants there today (like roundup does), I have been experimenting with a mixture of vinegar, water dawn and Epsom salts. We live on a major river (Detroit River/Lake Eerie) and do not want roundup running into the water supply. Not sure our cocktail is all that much safer for the water (we are told it is) but it works quite well. Best of all it saves a trip to home depot since we usually have all of those things around already.

There are stronger things than roundup that kill the roots also something that stops seeds from germinating. Wiping out existing plants with round up will not keep roots from growing new plants and will not stop seeds from germinating. Killing today weeds does not eliminate the weeds long term and they come right back. basically you need to mix in a kill everything chemical cocktail, then wait, then kill anything new that grows and mix again, then wait, then plant. Be careful what you use because some chemicals will sterilize your soil for a year or more. Just do what the "professionals" do - read the directions. News flash, the "professional" lawn care people did not go to college for this, they are not chemists, they read the instructions and talk to people, call the manufacturer with any questions. You can do that too.

this is what it says on the company's web site:

"Total Lawn Renovation Round Up is applied to nullify the existing vegetation in the lawn. Several days later, quality seed is sliced into the soil and placed at the proper depth for maximum germination. .. "

i am not surprised by the difference of opinion. i will talk to a couple of lawn guys before i proceed. soon i am removing about 19 trees on the property and after that i want to work on the lawn. which will be soon as trees are going next week.

Good discussion/information on Round Up at link below. A variant of this chemical was used as a defoliant in Vietnam.

now, i am not mr natural organic or anything close to that but it seems like a lot to apply it to my entire yard. is this something that you would feel comfortable doing?
NOOOOOOOOOO! That is highly toxic to the environment AND creatures AND has something to do with killing off bees.

There are methods of killing weeds just as good without all the danger and destruction. Don't do it! Don't even squirt one little weed between the pavers. It's totally unnecessary, due to lazy people who wanted to "buy" something to take care of a problem, and in no small part due to lawn services.

You know you can even pressure spray (with a pressure spray nozzle from Home Depot) a weed between pavers, and poof, it's gone! No poison, no danger.

Once you get your grass healthy (re-seed if necessary), it will crowd out most weeds. Then address just those weeds left over.

So check with your local code enforcement officer. It's not like the yard is set on fire like Napa was just on fire. It's done with a flaming torch. It's all very controlled.
