Doublefile viburnum is a beautiful flowering shrub that is perfect for adding color and interest to your landscape. This deciduous shrub blooms in the spring with large, white flowers that are arranged in double rows along the stem. The flowers are followed by blue-black berries that are popular with birds. The leaves of the doublefile viburnum turn a deep red in the fall adding even more interest to the plant. This shrub grows best in full sun to partial shade and prefers well-drained soil. It is relatively low maintenance and is also deer resistant. With its showy flowers and berries, the doublefile viburnum is a great addition to any landscape.
About soil conditions, doublefile viburnum prefers rich and moist, but well-drained soils, in full sun to part shade. It is a good choice for foundation plantings and hedges, but does require regular pruning to maintain its shape.
Like the other plants, the doublefile viburnum needs sunlight to grow. However, this plant is tolerant of shady conditions and does not need direct sun to prosper. In fact, too much sun can cause the leaves to scorch. The doublefile viburnum will do best in a location that receives partial sun to partial shade.
The temperature condition that is required for the growth of the doublefile viburnum is one that is cool to cold. These plants prefer a range of temperatures that are between 50 and 70 degrees Fahrenheit. They can tolerate brief periods of time outside of this range, but prolonged exposure will damage the plant.
Ideal humidity condition for this plant is 50%. Like most of the other plants, it does not like to be too wet or too dry. The leaves may start to turn brown if the humidity drops below 40%. If the humidity becomes too high, the leaves may start to turn yellow.
For the fertilizer, this plant does not need much. A general-purpose fertilizer will work just fine. Just be sure to not over-fertilize, as this can lead to problems. As for the roots, they are generally quite deep and don't need much attention. Just make sure they are getting enough water.
Pruning is a critical step in keeping your doublefile viburnum healthy and looking its best. This shrub is known for its beautiful, showy flowers, so you'll want to make sure you prune it in a way that encourages new growth and blooming. The best time to prune your doublefile viburnum is in late winter or early spring, before new growth begins. Start by removing any dead or diseased branches. Then, cut back any overgrown or leggy branches to encourage new growth. Finally, shaping the shrub by pruning back any long or straggly branches. With proper pruning, your doublefile viburnum will continue to thrive for many years to come.
Propagation of the doublefile viburnum is typically done through softwood cuttings taken from new growth in the spring. The cuttings should be about 4-6 inches long, with the bottom 2 inches being buried in moist potting soil. The cutting should then be misted regularly, and kept in a location with indirect light and moderate humidity. Once the cutting has rooted and new growth appears, it can be transplanted into a larger pot or into the ground.
Usually, the plant growth rate is rapid during the first few years after establishment. After that, the growth rate slows some but is still considered fast when compared to most other shrubs. A 10-year-old doublefile viburnum may be 6 to 8 feet (2 to 2.5 m.) tall and wide, while a 20-year-old plant may be 10 to 12 feet (3 to 3.5 m.) or more in both dimensions.
Common problems for this kind of plant are wet conditions or over-fertilization. Wet conditions can cause the leaves to turn brown and drop off the plant. If the plant is over-fertilized, the leaves may turn yellow and fall off as well.
