Azaleas are shallow rooted and require lots of water in a well-drained and aerated soil.
If an illness results in the plant check these clues. Poor growth, overall yellow and small foliage and a general unthriftiness describe too many of our azalea plants. A number of reasons can cause our plants to fit that description and not to grow and flower as we expected. Generally, if we meet the cultural requirements of our azaleas they will be attractive in foliage and in flower. Gardeners will have more success if they prepare a bed of azaleas rather than individual plantings.
