Catawba Rhododendron Growth Rate, Bloom Time, Propagation, Size

Catawba Rhododendron is a huge broadleaf perennial, rounded to spreading, a multi-stemmed shrub of the blueberry family that typically forms dense thickets. It's indigenous to the Appalachian Mountains' eastern woodlands, and especially the Blue Ridge region, where it grows on mountainous slopes and ridges. It can attain heights of up to 20' feet, though it becomes thin and rangy when grown in less-than-ideal conditions. Its big flower buds grow before flowering and burst forth in late spring to early summer with stunning pink to light purple flowers. As it develops, the bark turns gray-brown and crusty. It is frequently employed as an attractive, leathery, broadleaf perennial showpiece plant, in mass planting, or hedges.

Plant this shrub in partial shade in acidic, rich, well-drained but wet soils, supplementing with acidifying additives as needed. If your soil is neutral or alkaline, you will most likely need to use acidifiers on an annual basis. Because the root system is thin, annual mulching will assist in retaining moisture and maintaining consistent soil temperatures. It is critical not to allow the soil to dry up, as this will damage the roots. While it can withstand the morning heat, it needs protection from the severe afternoon sun and wind. It can withstand practically complete shade. Because it is native to mountainous areas, it prefers lower temperatures in the summer months.

Catawba Rhododendron Growth Rate

This shrub grows slowly, with annual height increments of fewer than 12 inches. Hardiness Zones 4–8 are suitable for the catawba rhododendron. This shrub is a flowering shrub as well as a perennial bush. It retains its foliage all year and blooms profusely in the spring. This shrub thrives in full sun and partial shade, preferring a minimum of four hours of direct, unfiltered sunshine per day. Rhododendron Catawba thrives in soils that are acidic, loamy, moist, rich, sandy, silty loam, and well-drained.

Catawba Rhododendron Bloom Time

A medium shrub with pink to purple flowers that grows on ridges over 3000 feet. The purple Catawba rhododendron blooms from the 1st week of June to the 3rd week of June.

Catawba Rhododendron Propagation

Rhododendrons can be grown from seed. However, cuttings can also be used to create new rhododendron plants. If you don't have access to seeds or want to ensure that your new rhododendron grows with the same bloom color and other features as the plant from which you obtained a cutting, rooting a cutting is a good option. To ensure that the rhododendron is adequately hydrated before cutting it, water it 1-2 days before cutting it. If you've gotten a lot of rain recently, this may not be essential.

Catawba Rhododendron Size

Rhododendrons don't have a maximum size and can grow perpetually. They range in size from the dwarf, ground-hugging species that reach 16 in. (40 cm) in 10 years to huge tree-like examples that reach 20 ft. or more in height (6 m). Moisture and the length of the growing season will both have a significant effect on their pace of growth.
