Holden's™ Red Rhododendron

Plant in moist, well-drained, acidic soil (pH 4.5-6.0) with generous organic matter. Space 4-6 feet apart. Water thoroughly after planting and mulch 2-3 inches deep, keeping mulch away from the crown.

Water deeply and consistently throughout the growing season. Prune lightly immediately after flowering. Fertilize in spring with an acid rhododendron fertilizer. Developed at the Holden Arboretum for exceptional cold hardiness in northern climates. Red produces vivid, rich red flowers on a well-formed, cold-hardy shrub- one of the most deeply colored and cold-hardy red rhododendrons available. Monitor for lace bugs. Largely otherwise pest-free.
