Before planting, set pots on saucers to protect paving from water stains, and fill them with top-quality organic potting soil that contains boosters and conditioners, such as mushroom compost, worm castings, and oyster-shell lime. For acid lovers, like blueberries, try an organic azalea-and-camellia mix. Shown: 'Sunshine Blue' Blueberries.
