Like many others I use packing peanuts in my flower containers. I don't have to use as much potting soil, and it keeps my containers lighter. This year I went to go change out the soil in my biggest container. I had to hand pick out each peanut from the soil. What a chore! When I went to replace the peanuts this time, I put them in an onion net bag and tied the bag off. Next time I go to change out the potting soil it will be a snap!
