Viburnum Opulus

• Native to Europe and parts of Asia, Viburnum Opulus has been cherished in gardens for centuries for its ornamental beauty and adaptability.
• Produces clusters of white lacelike flowers in spring that resemble snowballs, creating a spectacular floral display.
• Bright red berries appear in autumn and persist into winter, providing food for native birds and adding vivid colour to the garden.
• Deciduous foliage turns stunning shades of burgundy, red, and purple in autumn before dropping for winter.
• Grows as a rounded, spreading shrub reaching 3-4 metres tall and wide at maturity.
• Loved for its low-maintenance nature, seasonal interest, and ability to attract wildlife to the garden.

• Water deeply once or twice weekly during warmer months, allowing soil to dry slightly between waterings. Reduce frequency in winter when growth slows.
• Position in full sun for best flower production and autumn colour, though part shade works well in hot inland areas of Australia.
• Plant in rich, well-drained soil with plenty of organic matter. Add compost at planting time and mulch annually.
• Feed with a complete slow-release fertiliser in early spring as new growth emerges. A second light application in summer supports berry development.
• Prune immediately after flowering to shape the plant and remove crossing branches. Avoid heavy pruning as this reduces next season's flowers.
• Tolerates a range of soil types including clay, but drainage must be adequate to prevent root problems.
• Monitor for pests during spring and summer, particularly aphids and beetle larvae on new growth and leaves.
• Performs best in cooler Australian climates with distinct seasons, struggling in tropical and subtropical regions with high humidity.

• Plant in full sun to part shade for best flowering and autumn colour, though it tolerates shadier positions in hotter Australian regions.
• Water regularly during establishment and dry periods, keeping soil consistently moist but not waterlogged. Reduce watering in winter when the plant is dormant.
• Mulch around the base to retain moisture and keep roots cool during Australian summers. Use organic mulch like wood chips or compost.
• Prune after flowering to maintain shape and remove dead wood. Viburnum Opulus flowers on old wood, so avoid late winter pruning.
• Feed in early spring with a balanced slow-release fertiliser to support vigorous growth and abundant flowering.
• Tolerates frost and cold temperatures well, making it ideal for cool-climate Australian gardens in Victoria, Tasmania, and the Southern Highlands.

• Aphids can cluster on new growth and flower buds, causing distorted leaves and sticky honeydew. Spray with horticultural oil or a strong jet of water to remove them.
• Viburnum beetle larvae can skeletonise leaves in spring and summer. Inspect regularly and remove affected foliage or use appropriate organic insecticides.
• Powdery mildew may appear as white patches on leaves in humid conditions. Improve air circulation and avoid overhead watering to prevent fungal issues.
• Root rot can occur in poorly drained soils, causing yellowing leaves and wilting. Ensure excellent drainage and don't overwater, especially in heavy clay soils.
• Scale insects may attach to stems, appearing as small bumps. Treat with horticultural oil during the dormant season.
