Many home gardeners place Styrofoam packing peanuts in the bottoms of pots and large containers
before filling with potting soil. It’s a great idea as it allows for drainage and reduces the
weight of each potted plant. This method also works with hanging baskets and flower boxes where
you want to avoid excess weight. However, when repotting a plant the loose peanuts are a pain
to remove from the soil. An easy way to avoid this problem is to first pour the peanuts into a
mesh onion bag before placing them in the base of a pot. When you repot the plant, the bag
containing the peanuts is easy to extract resulting in Styrofoam-free soil that can be safely
added to your compost pile.
