This guide will walk you through everything you need to know to cultivate a healthy and thriving copper top viburnum.
Understanding the Copper Top Viburnum
Before you rush out to purchase one, let’s get to know this fantastic plant a little better. Knowing its key characteristics will help you provide the best possible care.
What is Copper Top Viburnum?
Copper top viburnum (Viburnum dilatatum ‘Henneke’) is a deciduous shrub prized for its vibrant foliage. Its new growth emerges with a beautiful coppery-red hue, hence the name "copper top." As the foliage matures, it transitions to a lush green, and then in the fall, it explodes into shades of red and burgundy.
Key Features:
- Size: Typically grows to a height and width of 6-8 feet, though some varieties can be slightly larger.
- Foliage: Copper-red new growth, maturing to green, then turning brilliant red in fall.
- Flowers: Clusters of white flowers appear in late spring to early summer.
- Berries: Bright red berries follow the flowers and persist through the winter, providing food for birds and adding winter interest.
- Hardiness: Generally hardy in USDA zones 5-8.
Planting Your Copper Top Viburnum
Proper planting is essential for the long-term health and vigor of your copper top viburnum. Here’s a step-by-step guide to ensure success.
Choosing the Right Location:
- Sunlight: Copper top viburnum thrives in full sun to partial shade. At least 6 hours of sunlight is ideal for best flowering and fruit production.
- Soil: Well-draining soil is crucial. Amend heavy clay soil with organic matter like compost to improve drainage. The ideal soil pH is slightly acidic to neutral (6.0-7.0).
Planting Instructions:
- Dig the Hole: Dig a hole twice as wide as the root ball and just as deep.
- Amend the Soil: Mix the soil removed from the hole with compost or other organic matter.
- Remove the Plant: Gently remove the copper top viburnum from its container, being careful not to damage the roots. Loosen any circling roots.
- Place the Plant: Position the plant in the hole so that the top of the root ball is level with the surrounding soil.
- Backfill the Hole: Fill the hole with the amended soil, gently tamping it down to remove air pockets.
- Water Thoroughly: Water deeply to settle the soil around the roots.
- Mulch: Apply a 2-3 inch layer of mulch around the base of the plant, keeping it a few inches away from the trunk. This will help retain moisture, suppress weeds, and regulate soil temperature.
Caring for Your Copper Top Viburnum
Once planted, your copper top viburnum needs regular care to flourish. Here’s what you need to know about watering, fertilizing, and pruning.
Watering:
- Water deeply and regularly, especially during the first year after planting.
- Established copper top viburnums are relatively drought-tolerant, but still benefit from regular watering during dry spells.
- Avoid overwatering, which can lead to root rot.
Fertilizing:
- Fertilize in early spring with a balanced fertilizer, such as a 10-10-10 formula. Follow the package instructions for application rates.
- Alternatively, you can apply a slow-release fertilizer in the spring.
- Avoid fertilizing in the late summer or fall, as this can encourage new growth that may be susceptible to frost damage.
Pruning:
- Prune your copper top viburnum in late winter or early spring before new growth begins.
- Remove any dead, damaged, or crossing branches.
- You can also prune to shape the plant and control its size.
- To encourage bushier growth, prune back the tips of young branches.
- For older, overgrown plants, you can rejuvenate them by cutting back a third of the oldest branches to the ground each year for three years.
Common Problems:
| Problem | Symptom | Solution |
|---|---|---|
| Aphids | Small, sap-sucking insects on new growth | Spray with insecticidal soap or neem oil. |
| Viburnum Leaf Beetle | Skeletonized leaves | Handpick beetles and larvae. Use insecticides specifically labeled for viburnum leaf beetle if necessary. |
| Powdery Mildew | White, powdery coating on leaves | Improve air circulation. Apply fungicide if needed. |
| Root Rot | Yellowing leaves, wilting, stunted growth | Ensure good drainage. Avoid overwatering. |
