catawba rhododendron

Catawba rhododendron (Rhododendron catawbiense Roseum Superbum) thrives in moist and well-drained soil, yet does not tolerate long periods of standing water or overly wet soils. Water deeply and thoroughly, once weekly during the spring and summer months. Reduce watering to twice monthly during the fall and winter months when the plant is dormant. Empty the water-holding saucer below the pot after watering to keep the roots from sitting in standing water. If the soil begins to dry out, water more frequently.

Catawba rhododendron (Rhododendron catawbiense 'Roseum Superbum') grows best in partial to full sun. During the spring and summer months, the plant should receive 4 to 6 hours of sunlight each day, with ideally 3 to 4 hours of direct sunlight in the morning and indirect light in the afternoon. In the late fall and winter, the plant should receive at least 3 hours of indirect light each day to prevent dormancy.

The Catawba Rhododendron, or Rhododendron catawbiense 'Roseum Superbum', generally only requires pruning once each spring, immediately after the plant has finished flowering. Generally, only the oldest flowering stems should be removed at this time, being careful to avoid cutting into green, woody growth. Leaves and other foliage should not be removed during this period of pruning, as these plants generally only require minimal maintenance. If necessary, further pruning can be done in mid- to late-summer to help shape the plant and encourage fuller growth. Bushes may need pruned annually, while taller shrubs may not need pruning every year.
