watering
Catawba rhododendrons need regular watering while they are actively growing, from spring to fall. During this period, it is best to water deeply and thoroughly once each week, allowing the top inch of soil to become dry. Avoid frequent, shallow waterings as they can lead to root rot. During the winter months, water when necessary to keep the soil slightly damp.
sunlight
Catawba rhododendrons requires full sun to partial shade, as they prefer about 4 to 6 hours of direct sunlight per day. However, they require some filtered indirect light the rest of the time. In hot and humid climates, Catawbas should be protected from afternoon sun. In climates with more moderate temperatures, Catawbas can benefit from morning sun. Planting against a north facing wall or against the east side of a building will provide enough morning light to encourage flowering without excessive heat.
pruning
Catawba rhododendron should be pruned twice a year - once in late winter/early spring and again in late summer. When pruning in the winter/spring, prune back any dead, diseased, or damaged branches as well as any growth that appears weak. Remove any branches that grow back towards the center of the plant or that are growing too densley. In late summer, lightly prune the tips of the stems to promote a denser habit and also remove any fading flower heads. Avoid pruning too much in spring to preserve the flowers.
