Advice on using plastic grocery bags for filler for container gardens

I have heard of using Styrofoam pellets at the bottom of pots, has any one used crushed up plastic grocery bags the same way, does this work as filler and drainage?

    @jnet I think the only problem would be the plastic interfering with drainage from the pot. Usually when you use styrofoam containers the water can still drip down to the drainage hole, but with bags this could be totally blocked causing a water logged container. This happens with container that don't have an arranged drainage area - my tin containers have a problem this way and I have to protect it from the rain at times. You could still use them for fill provided there was still access to the drainage for the container - strategic arrangement will be crucial.

      @Jnet I think the knots will help, but you will still have to prevent them from blocking the drainage - perhaps with an upside down clay pot and the bags around that.

    My friend crushes plastic milk jugs and uses those; much neater than pellets, and very effective.

    I would use something that would allow water to travel throigh incase you or the rain might over fill. I have read that some people use coffee filters, in the past i have used rocks that are larger than the drain hole so they dont fall through, yet allows the over flow of water to escape so your plants do not drown.

    Last year I used cut-up styrofoam egg cartons and plastic rinsed-out Meow Mix cat food 'cups'... Worked well... And I placed a piece of used dryer sheet over the hole. Both worked well.

      @Marianne Cerrito thank you for the idea, I have plenty of dryer sheets and have been wanting ideas for the used ones

    I use crushed up plastic water bottles in the bottoms of my larger planters. Great for drainage and makes it lighter -less dirt- and easier to move around. Also keeps them out of landfill.

      @Cathy622 I am planning on using the plastic soda bottles but whole with the caps on tucked in to the sides. The "planters" are painted tires. Thank you for your help

    I have used packing "peanuts" in the bottom 1/3 of large pots. I then add my potting soil shaking it to let it settle, then adding more until it reaches what looks like full. Water well & add your plants. There is no problem with drainage. This is a great way to use up those non biodegradable packing peanuts & use less potting soil. Works well & holds up ..... forever!

      @Sandra B thanks, I have heard if this, the reason I asked about the bags is I have a lot of them. Lol
