what i use and it lasts most of the season here, and its wet till late july, is glyphosate aka generic roundup and ecompozar which is a sterilizer. glypho kills the weeds and ecomp keeps them dead. good luck [Reply]
Got a similar situation with a rock garden like Scho. But also have a retaining wall flower bed type deal that’s only 2-3 feet tall at moms house and she wants me to kill off everything so she can start new with her choice of plants and shrubs.
I’ve had luck using 45-75% vinegar diluted and mixing with a cup of salt, cup of borax, and dish soap. It’s a YouTube recipe out there that’s free of roundup ingredients etc. I used it in the brick paver spot she has and the rock garden with good luck.
My question is can I harm the soil for future plants/shrubs this spring with any of those ingredients? I’m in Iowa (great rich soil) and will probably kill it off in the next week. So by April/may should the soil be alright to add new plants/shrubs safely? [Reply]
My dad had rock landscaping in Arkansas. He used a propane flame thrower and just burned them out of rock. Got rid of all the pine needles that way too. [Reply]

The acidity of the vinegar and salinity of the salt that remains in the soil after treatment and the amount of rain/snow and wind you get over the winter will determine that. I would suggest taking soil samples to your local extension office in the spring to see what, if any, remains and amending the soil to "fix" it. [Reply]

That makes plenty of sense and sounds like a smart idea. I could actually scoop out most of the soil and just replace it. It’s not a huge amount. Thanks! [Reply]
