Rhododendrons are queens of the late spring garden. Blooming heavily with swathes of bright intense color and bridging the gap between spring and summer. Rangoon Rhododendron has a deep red color flower on a shorter and much more compact frame. Rangoon is perfect for a smaller garden or to use at the front of a woodland garden. The large, evergreen leaves provide year round interest that compliments every color of the rainbow.
Rhododendron is a great low-maintenance shrub to include in the garden. Pruning and deadheading is rarely needed for Rangoon. The flowers are self-cleaning while the natural shape is mounding and slightly spreading. Rhododendrons thrive in woodland settings where they work as an understory plant to provide shelter for wildlife such as birds and small mammals. The full bloom flowers absolutely hum from the swarms of native pollinators that they attract. Rangoon will fit into a broad range of garden plans. Asian inspired, cottage garden, woodland garden or a minimalist urban design.
Rangoon Rhododendron Care
Rangoon Rhododendron will be happiest in a dappled shade site that has acidic soil. Full sun is usually tolerated early in the morning. Soil texture needs to be average to sandy, moist but well draining. Consistent watering is important for the first 2-3 years until the shrub is fully established. During extended hot and dry periods, supplemental watering will be required.
Mulching Rhododendrons each fall will help to improve the structure and moisture holding abilities of the soil. Using an organic compost will also add nutrients to the soil. Fertilizing in the early spring with a well balanced, slow release food formulated for acid loving shrubs will support flower formation and leaf color. Any pruning should be done after blooming ends, in the early summer. A light cutting back of branches will help Rangoon to keep its mounded shape.
Rangoon Rhododendron Spacing
Rangoon has a naturally mounded shape that is 3-4 feet high and 4-5 feet wide at maturity. Planting shrubs at 4 feet on center will provide plenty of space for proper air circulation.

Old Wood
?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
