    I am a homeowner who decided to tear out a mulch bed after it was taken over by weeds growing through the fabric. Either fabric is useless or I am not doing it right. I read about using a weed preventative like Preen before putting mulch back down and not using the fabric. Any advice for a joe shmoe who is sick of weeds. Thanks you.

    That is easy, you went cheap on the mulch..Go at least 6 inches deep and have zero (after it compacts). I had 30 yards for my own property and after almost 5 months that was many 10 weeds...

    are you trying to cause disease to start on the landscape plants in a bed with 6" deep mulch?

    Spot treat with roundup but be careful around other plants. Pulling weeds (IMHO & experience) does next to nothing unless you get the root...clover, dandelion, etc. you almost can never get by the root. Skip on the weed fabric IMO, waste of time/money. UNLESS its stone, then I use fabric. Oh ya, and use pre-emergent. Not sure about preen though.

    I have heard the 6" mulch thing before. So this is not a good idea? I had 3" on top of the soil before I cleaned up the bed. I have been slacking on the weeding part due to working long hours and to many projects going but now I have the time to dedicate to this issue. Thanks for the advice though, its appreciated.

    I will say that removing crab grass in front of the bed, lots of it, in order to plant grass is a bear. Glad I don't do lawn care for a living.

    Don't use weed block, it's a waste. Preen will help, but it's only a pre-emergent, it won't kill the root. It just prevents seeds from germinating. Glyphosate will kill to the root, but be careful to only spray the weeds. And in my opinion, 6 inches of mulch is way too heavy. 3-4 inches in optimum on new installs. Any thicker and it tends to be a tad unhealthy for plants.

    Landscape fabric= waste of money. Get Preen, HD and Lowes sells it. I have used it, work great. It won't kill weeds that have started, but will stop new weeds from germinating.

    Wow, 6 inches of mulch? How do you plant annuals in 6 inches of mulch?

    Anyways, good weed fabic works great in stone beds, the problem you run into is putting mulch/compost on TOP of the fabric, this is what the weeds germinate in. Then the weeds roots grow into the fabric, not up through.
