We recently moved to Louisiana, and moved into our house in January. I could pull weeds every single day and never get finished! So I bought Preen, sprinkled the entire container on our numerous mulched beds, and looked forward to less weed-pulling. A month later, it hasn't made one bit of difference. I understand that SOME weeds will still grow after Preen, but every kind that was there before, keeps popping up.
Anyone else have good or bad experience with Preen?
I use the Preen for GARDEN BEDS granules for years. And am very pleased. Of course I also have double landscape fabric, and 2 inches off mulch too.
For my lawn - a yard service handles that. And I've been LESS than pleased.
I'll have to talk with them about that AGAIN. A guy two streets over has used them and his yard is always dark green and like a golf course. I've asked a couple of times why can't my yard look like that and if he get some extra level of service or treatments I don't. They say no. I do know he has a different grass than I do. And the service says, that, plus the conditions from block to block can make a difference. Sorry, I digress......
You have to apply Preen under the mulch and on top of the mulch. Preen only prevents the germination of seeds/weeds. It won't prevent the weeds from growing that have already started to sprout. Like Charles said, it's like birth control for weeds.
you can't expect any product to work if applied over mulch. remove the mulch, roundup weed and then put down preen.put mulch back on and watch to kill any that may have been missed.

Not really feasible. The mulch is pretty thick, and there are entirely too many mulched beds for me to go to that much work right now. (I'm in the middle of wallpaper removal & painting, and sanding/priming/refinishing every faucet and other misc items throughout the house. Busy girl!)
And honestly the weeds that I'm pulling are sprouting and growing in the mulch (roots aren't even down to the dirt). So Preening the dirt below won't stop the weeds from growing in the mulch. I just spent part of today applying RoundUp again. (I've tried to stay on top of the problem by pulling some of the weeds each day, but there's just too many.)
Is there a RoundUp that's safe for flower an vegetable garden beds?
"Broad spectrum" means just that. It will kill what it hits in an ornamental bed. So you have to be careful, spray when the wind is calm, and adjust the nozzle for a stream or heavy droplets. I've used a paintbrush mounted on a broom handle, and I also have one of those applicator thingies that lets you roll the product onto weeds. The problem with that thing is that it doesn't hold verymuch chemical and I'm always refilling it. Works great though. It is best to spray herbicides early in the morning when the temperatures are cool and the winds are calmest.
