I use RM 43. Doesn’t quite get a year, but easily about 8 months. I bought 2.5 gallons of concentrate for about $100 at tractor supply. I expect it will last me 2 years, before I run out. I really like it even thought it doesn’t get me a year. --66.169.xxx.xxx

Where I feed sunflower seeds to birds and squirrels Nothing grows. No weeds come through it and anything in that spot dies including small trees. Try a bag of sunflower seed and spread it there. It doesn't look to bad and you can cover it with a nice mulch but seeds will sprout in the mulch. Sunflower seed has nicotine in it so it might be that killing or preventing weeds. I ate preshelled toasted sunflower seeds to quit smoking after I cut back to very few cigarettes a day forty years ago. --71.104.xx.xxx

Thanks. There is a product at Home Depot that claims it can prevent them for up to a year but I didn't really believe it. --72.188.xxx.xxx

Rock salt. Cheap , found where water softener salt is sold. --50.229.xx.xxx

Yeah it works all season for me, but we have winter frost here so I can’t really say for sure if it lasts 12 months. But I don’t see anything where I spray it till the following spring. --70.20.xx.xx

Be careful with any of these chemicals,it can get into your water supply if you have a well and can cause cancer --104.229.xxx.xxx

--70.160.xxx.xxx

Chemical should kill everything. Paper will rot in a year or so (dependent on your weather) but will hold down anything the chemicals miss. You will need to "touch up" every few years. --72.70.xxx.xxx

I’ve tried a lot of these. The only one that worked was Ortho GroundClear. --68.118.xxx.xx

I found round up QuikPro and Spectracide weed killers work well. --66.30.xx.xx

Ortho Ground Clear was actually the one I was considering before I posted this. --72.188.xxx.xxx

There is also corn gluten which has natural pre-emergent inhibitors. You can find I believe on gardener's supply. No reason to use toxic stuff if you can avoid it. --99.203.xxx.xxx

Small Potatoes, I tried the vinegar solution once this summer and my sprayer kept clogging (might need a new one). The landscape company about to do a permeable patio at my house said I will need to do that twice a year. They said to heat the vinegar solution to dissolve the salt. Do you heat it? --73.17.xx.xxx

Any time you use a sprayer it should be thoroughly cleaned afterwards.the small Off the shelf ones don't last long. I sprung for a 4 gal backpack sprayer w pump bar from harbor freight. It was on sale and the same price as a medium handheld one from Lowes. Allows me to drive around and hit a few locations at once. I have to admit it's not my favorite task and as the season wore I did not keep up everywhere w it. --24.194.xxx.xxx

Thank you for that information. I see a backpack sprayer in my future that I will clean after using. --73.17.xx.xxx

Keep in mind that as Ken said these chemicals will cause cancer. Also putting down cardboard or paper and wood mulch will attract termites so I would not do this. I put down a thick black plastic and punch holes for the plants and then I put down pine needles as my mulch as the termites do not like pine needles and the acidity will also help with weed control. I don't see mulching around trees as a good idea either as it cause the roots to grow to the top of the ground. However I am not a gardener or landscaper. Just my experience and experiments. --73.120.xx.xxx

6x I will disagree that cardboard will attract termites. J being in fla prolly has some kind of bug plan in place as well. Mulch should not be placed w/in 2" of tree trunks and ideally not mounded up like you see sometimes. Mulch helps retain moisture. To keep roots growing down deep infrequent watering is the key. Most folks water improperly. The ground should be wet (not leaves) and applied til it pools, then take the hose away. Reapply water til it doesn't drain right away. Never water in the middle of the day, it will put lawns/plants in shock. --24.194.xxx.xxx

Thank you Small potatoes. I put mulch around some new trees that I planted as the nursery suggested which is in line with what you described. I then saw on a show later on how mulching around trees is not good as it causes the roots to come up to the top of the ground so I went and checked and sure enough they were right. They said that this would kill the trees so I removed the mulch and the trees are doing great. It could be different in Florida though. --73.120.xx.xxx

If you can get your hands on an old flame thrower ,forget all the other garbage, fifteen minutes and you’re done,good for a year or longer,maybe an old government surplus place,if you can find one of those...........charlie --32.214.xxx.xx

Hadn't thought of that Charlie. I wouldn't do it too close to any buildings though. --73.120.xx.xxx

Charlie, the flame thrower is tedious work and not much fun on a hot summer day. I find it discolor the pavers sometimes for a period if time and w the deep rooted ones they are still alive deep down. Overall it is an option. --24.194.xxx.xxx

I ended up buying Round Up Extended Control, sprayed it on yesterday. I'm not on well water so not concerned about contamination. --72.188.xxx.xxx

Small potatoes,I think it would be a shock for the grass if I watered it at all. I do have a hose and it’s hooked up but that’s as far as it goes Let some one else do the honors............... Charlie.......besides the weather here in Connecticut is just too darned cold for that kind of nonsense...................? ? --32.214.xxx.xx

Small Potatoes,Vinegar might do the trick,I know it goes good on French Fries.....................charie............ --32.214.xxx.xx

Ken,Here in Connecticut The lads take care of the water.Lake Saltinstall.Keeps them busy.......charlie.......besides someone has to do it,so why not................?.....?......? --32.214.xxx.xx
