watering

The Catawba rhododendron, also known as Rhododendron 'Catawbiense Album', is a species of evergreen shrub that thrives in moist, well-drained soil. For best results, the Catawba rhododendrons should be watered regularly and deeply. During the summer months when the plant is actively growing, it should be watered at least twice a week, allowing water to thoroughly soak the soil. During dry spells, water every other day. During the winter months, they should be watered only once a week, but with enough water to keep the soil slightly moist. It is important to not overwater the Catawba rhododendron, as this can lead to root rot. Avoid moisture accumulation around the plant and never allow it to sit in standing water.

sunlight

Catawba Rhododendrons prefer an area with full or partial sun. In regions with hot summers, they should receive some afternoon shade. Some plants can tolerate full shade, while others may not flower well with less sunlight. Spring and fall are the best times to plant Catawba Rhododendrons as the temperatures are milder and there is more sunlight, allowing the plant to establish itself before winter. During the summer months, the plant still needs at least 4 hours of direct sunlight.

pruning

Catawba Rhododendron should be pruned annually in late winter or early spring, before any new growth appears. Regular pruning will help to shape the bush and keep its beautiful blooms coming back year after year. When pruning, it is important to remove any dead or damaged branches, as well as any that are growing inside the shrub. During the first few years of growth, pruning should focus on encouraging strong, healthy branches. Some shaping can be done however, take care to cut branches at the right angles to ensure the shrub maintains its natural shape. When pruning older shrubs, pay particular attention to the top of the plant as this area can easily become overgrown and reduce blooms. Once all the dead and damaged growth has been removed, thin out any overcrowded branches and shape the bush as desired. The most important rule to remember when it comes to pruning rhododendrons, is to not prune after August as any late season trimming can reduce blooms the following season.
