    just got a large mulch job 10-12 yds. Well a little big for me. Here is the ?, the mulch is going to be around a large swing-set/ jungle jim. What would be the best weed guard preen or plastic? I say the plastic because there are no plants to deal with, it would also last longer, right? I also thought plastic against the dirt and then a little preen just so there is no weeds what so ever. Also i am thinking with the heavy traffic of the kids playing that weeds would have trouble germinating with the mulch being trampled on. Any suggestions would be great. thanks

    Go with the plastic. Pre-m of any kind would not be good around children. Preen contains Trifluralin. It's a good pre-m for the beds but not for play areas.

    thanks for the insight. i kind of thought preen would not be good for the kids sake.

    Read the specs on the preen. Prolly not a major problem using it. I don't ever suggest using plastic, especially if it's a high traffic area. The mulch will not bond and will tend to slide around on the smooth surface. If you must use a barrier use landscape fabric. Even that will slide until the mulch settles. Once the mulch begins to decompose weeds will grow in it unless treated.

    Weed seeds will still germinate in your mulch no matter what you have below it. Once they do germinate the roots can get caught up in whatever fabric you have below. Once you pull on the weed the fabric will come with it. Then you ned to try to tuck the fabric back in under the mulch. Fabric is nothing but a pain in my book.

    If it's a play area, you probably should be using a mulch that is rated for playground use. Around here it's called Tenderturf or Softstep, depending on the supplier. Basically it's wood chips, but they have passed a certification (I think it's an ASTM cert) that they are fine for playgrounds.

    DON'T use any plastic or fabric under ANY organic mulch. This has been discussed MANY, MANY times. The mulch will break down on top of the plastic/fabric and not incorporate into the soil. Then you will basically have soil on top of the barrier, and you will be right back where you started. As ML stated, the weeds will germinate on top of the barrier, in the mulch, and it'll be a major PITA!

    If it's a heavy use area, the kids will keep the weeds down pretty well.

    We do alot of playground installs, we have to work to code on all of them. If this is a new install the playground mulch (which is different than normal hardwood) should be anywhere from 12-18 inches deep for safety reasons. If you dig down this deep it helps to reduce weed growth also the depth prevents growth. Just make sure you are up to code on the playground material install. I also would not use chemicals. I know our material is cushion wood and i forget the other name but it is all certified by the state for use in playgrounds.

    Playground mulch or rubber mulch is a great thing for playgrounds. It has to be deep. At least 12".

    the homeownwe said that the playground people said it had to 6" deep, 6' around the structure. the thing is that the play area is connected to a preexisting mulch bed.
