How to Grow and Care for Judd Viburnum

Light: Prefers full sun to partial shade for optimal flowering and fruiting.

Soil: Well-drained, moderately fertile soil. It can tolerate a range of soil types but prefers moist loams.

Water: Requires moderate watering; water deeply when the soil is dry to the touch, but avoid waterlogging. Established plants can tolerate short dry spells.

Fertilizer: Apply a balanced, slow-release fertilizer in early spring. An additional application in late summer can boost flowering and fruiting.

Pruning: Best done immediately after flowering to shape the plant and remove any dead or damaged branches. However, this will eliminate the summer fruit display.

Propagation: Softwood cuttings can be used for propagation during the summer months, while semi-ripe cuttings are best taken from midsummer through autumn. Hardwood cuttings are ideal for winter propagation. Additionally, layering can be performed in the spring season, and grafting is most effective when done in late summer.

Pests and Diseases: Generally resistant to most pests and diseases. However, watch out for aphids, viburnum beetle, root rot and botrytis. Apply appropriate treatments as needed.

Following these care guidelines will help ensure a healthy and vibrant Judd Viburnum, offering fragrant flowers, attractive foliage, and berries that can serve as both an aesthetic and functional addition to your garden.
