What can I use to kill weeds in my flower bed?

Use PREEN throughout good for 6 months and reapply

put down a weed fabric in between your plants

I put a couple layers of newspaper down n it keeps weeds under control. Wet it down or a few lite stones keep it from blowing around

. Baskets around tomatoes can go right through paper n helps hold them.

Try adding Preen mulch to reduce weeds.

Thank you both..something to think about.

Hello. Permanently get rid of weeds, not possible sadly. Its a constant war realistically.

I have found the Preen products are pretty helpful. Check out reviews and the Q&A here to see if it could be used for your gardens weed eradication needs. There are different formulations to include organic.

Thank you..I've got bulbs planted and flowers in between. I need something that won't hurt flowers.

Thank you..I like the idea of organic.

Pull them and then sprinkle a layer of Preen down to prevent them -- available at your garden center.
