Rhododendron 'Holden'
CC BY-SA 4.0 · Web-optimized
Clusters of pink to rose-red flowers appear in spring on Rhododendron 'Holden', a compact shrub with glossy, dark green evergreen leaves. Its dense, rounded form generally reaches about 4 to 5 feet tall and wide at maturity. In Southwest Washington gardens, place it in dappled shade and shelter, with room for its eventual spread. Give its roots acidic soil with good drainage, supplying water during dry spells to keep the root area moist. The shrub fits a shaded foundation planting or woodland edge, where its spring flowers and year-round foliage remain visible.

Common growing concerns.
Symptoms can have more than one cause. These notes are a starting point for observing your plant and improving its growing conditions.
Phytophthora root rot
Stunted growth, yellowish-green leaves, wilting and branch dieback; dead leaves may remain attached.
Help your plant thrive
Start with disease-free plants in well-drained soil. Remove affected plants and practice sanitation.
Rhododendron lace bug
Pale stippling above the leaves and dark, crusty deposits underneath; repeated infestations can yellow the foliage.
Help your plant thrive
Check leaf undersides, especially by early to midsummer. Dislodge bugs with a strong stream of water directed underneath the leaves.
