Cultivation of Viburnum Dentatum L. Var. Deamii (Rehd.) Fern.
Viburnum Dentatum L. Var. Deamii (Rehd.) Fern. is a compact shrub that grows up to 10 feet high and 8 feet wide. It is native to the United States and is hardy in zones 3-8. Here are some tips for cultivating this plant.
Watering Needs
Viburnum Dentatum L. Var. Deamii (Rehd.) Fern. needs regular watering to thrive. During the growing season, water deeply and regularly, ensuring the soil remains moist but well-drained. Avoid overwatering as it can lead to root rot.
Fertilization

Propagation of Viburnum dentatum L. var. deamii (Rehd.) Fern.
Viburnum dentatum L. var. deamii (Rehd.) Fern., commonly known as Deam's arrowwood, is a deciduous shrub that belongs to the family Adoxaceae. This plant is native to the Eastern United States and is often used for landscaping. The easiest and most common methods of propagating Deam's arrowwood are through cuttings and layering.
Propagation through Cuttings
The best time to propagate Deam's arrowwood through cuttings is during the summer. Take cuttings that are 4-6 inches long from the current year's growth and remove all the leaves except for the top two or three. Dip the cuttings in rooting hormone and plant them in a pot filled with a mixture of peat moss and sand. Water them and keep them in a warm and humid place. Roots will form in 3-4 weeks, after which the plant can be transferred to a larger container or transplanted into the garden.
Propagation through Layering
Propagation through layering is another effective method to propagate Deam's arrowwood. In the early spring, select a low hanging branch and scratch the bark where it touches the ground. Remove the leaves from the scratched area and dust with rooting hormone. Bury the scratched area with soil and secure it in place by placing a rock or a brick on top. Keep the soil moist but not waterlogged. In about a year, new plantlets will have formed and can be separated from the parent plant and re-planted.
Disease and Pest Management for Viburnum dentatum L. var. deamii (Rehd.) Fern.
Viburnum dentatum L. var. deamii (Rehd.) Fern. or commonly known as Deam's Arrowwood, can be affected by several diseases and pests. Here are some of the common ones and ways to manage them:
Diseases
Leaf Spot: This disease is caused by the fungus known as Cercospora viburni. The infected leaves will have small brown spots, which will then enlarge and become tan or gray in color with a dark border. To manage this disease, remove and destroy the infected leaves to prevent further spread. Avoid overhead watering and instead opt for drip irrigation. Additionally, applying fungicides can also be helpful.
Powdery Mildew: This fungal disease is known to cause a white powdery coating on the leaves, which can be easily wiped off. Over time, the infected leaves will turn yellow and fall off. To prevent this disease, plant the Viburnum dentatum L. var. deamii in an area with adequate sunlight and air circulation. Avoid overhead watering and instead opt for drip irrigation. Apply fungicides for more severe cases.
Pests
Scale Insects: These pests attach themselves to the leaves and stems and suck sap from the plant. This will result in yellowing and drop of leaves. To manage scale insects, prune and destroy heavily infested areas. For more serious cases, use horticultural oils and insecticides.
Japanese Beetle: These pests feed on the leaves, flowers, and fruits of the plant. They will skeletonize the leaves, leaving only the veins. To control Japanese Beetles, manually remove them from the plant (shake them off into a bucket of soapy water) and apply insecticides when necessary.
By following these steps, you can help manage the diseases and pests that might affect your Viburnum dentatum L. var. deamii (Rehd.) Fern. plant and keep it healthy and thriving!
