Howdy folks: Cliff Notes: This question is whether if anyone knows a way to permanently kill vegetation and that nothing grows there again. Extended Version: I live on a large, rural property and want to have certain sections be permanently devoid of weeds, grass, raspberries etc. Every year the stuff grows, every year I spray it with Roundup and every year stuff grows back three months later. For flaps sake, I don't know how the weeds etc effortlessly grow in the face of herbicide but I can't get grass seed to germinate. In any event, one method mentioned on the interwebs is spraying salt water, another is throwing water softener salt pellets, another is to use an herbicide called Ground Clear. Any advice would be appreciated. Thanks!
Look into 'Pre-Emergents'. Most seeds laugh at herbicides. The stuff that works is probably pretty regulated.
Ground clear works for about 3-4 months...it's says "up to 6" but the more rain you get, the shorter that time actually gets. The one thing I've seen clear the ground bare for years is oil, specifically hydraulic oil. The neighbors haybine blew a line and he forgot to lock it in the transport position before removing the hose...so when he took the hose off the cylinder blew it's load everywhere...totally bare for years.
What the need for bare dirt? I get not wanting weeds, but I don't see any reason for bare dirt....not that isn't one...just don't see it. If I wanted something devoid of vegetation I'd probably put down white rock and spray it with Hyvar or the like once a year.
Most of the area surrounds my wood stacks. Dang weeds grow so high that they block sunlight from hitting the wood. I have no idea where the seeds come from.....I kill everything with Roundup, it goes to bare dirt and the following spring they grow again as if someone planted them.
Permanent vegetation killer would be rather hard on ground water & would likely seep to other areas. I use this stuff on driveways & pathways in the local cemetery. It works for up to 12 months, it will seep/run if you mix to heavily or it rains a lot after application. You might try salting the area. Roundup seems to require multiple applications throughout the season. I have found that just mowing around the stacks works best with an occasional pass with the weed eater.
