Azaleas should be planted in spring, when the weather is still cool and the plants are dormant. Planting in spring allows the shrubs to "wake up" in their new habitat. Choose a planting site with well-draining soil, indirect light, and a bit of protection from wind and harsh weather. Because azaleas require well-drained, airy soil, you can add compost or loam while aerating your soil before planting. This can be tough if your winter runs late, so wait until the ground thaws. Azaleas ordered from Michigan Bulb will be shipped at the right time for planting, and you can plant them at the depth at which they were potted. Planting azaleas is fairly foolproof!
