According to horticultural experts, viburnums are relatively low-maintenance once established. To ensure your plant thrives, follow these simple steps:
-
Light: Most viburnums prefer full sun to partial shade. Varieties grown in full sun typically produce more flowers and fruit.
-
Soil: They thrive in well-drained, slightly acidic soil. However, they are known for their adaptability to different soil types, including clay. Check out our blog on how to garden in clay soil!
