If the clutter on your property says one unit isn't enough, but your wallet disagrees, supplement your main unit with one of the less expensive, smaller models. There are three main types of such units, all of which go by descriptive names. $Corner sheds$ are made to fit precisely into a corner and run about 3 feet tall by 3 feet wide by 2 feet deep. Meanwhile, either a $vertical shed$ (5 x 3 x 4) or a $horizontal shed$ (3 x 5 x 4) may be just the handy outdoor storage building to fill your need for additional space.
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.
