10 Smart Uses for Old Plastic Bags

Plastic Bag as Plant Filler

Crumple bags to fill the bottom of a large pot that's too deep for your plant (but be sure not to cover the drainage hole, if it has one). You can cut down on the amount of potting soil needed, and since plastic packs less heft than dirt, you'll be able to move a big planter around with a bit less grunting.
