I love growing veggies and herbs in containers on my sunny deck. But, when it’s time to clean and store the pots for winter, I need to find a new use for the spent potting soil.
Many gardeners simply dispose of old potting soil in their garbage or city compost bins, but there are several ways to put that old potting soil to work in your garden:
1. Use it to top existing flower and vegetable garden beds
2. Spread it thinly over the lawn
3. Dump it in newly built raised beds as a start to filling them
4. Add it to your compost bins
