Garden Supply Storage - Garden supplies tend to end up everywhere, especially if you do any potting in your shed. Always make sure to have a clean surface to work on. Old crates work well to hang from your potting area, where you can put small bags of soil, pots and watering cans. For seeds and other loose items, hang a ribbon and attach clothes pin. As you get small packets of seeds, use the clothespins to hang from the ribbon, taking down as needed. This keeps them organized and out of your workspace, so you can make the most of your gardening.
Buying an outdoor storage building with a loft greatly increases storage capability, allowing you to store rarely used supplies overhead. For the exterior, build your own lean-to and attach it to the outdoor storage building to form a sheltered area for firewood.
