Plant Gold Prinz Rhododendron in well-drained, acidic soil. Choose a location with partial shade, avoiding direct afternoon sun. Space plants 4-6 feet apart. Water regularly to keep the soil consistently moist but not waterlogged. Fertilize in early spring with a slow-release, acid-loving plant fertilizer. Prune after flowering to maintain shape and remove dead or damaged branches. Protect from harsh winter winds and ensure good air circulation to prevent disease.
