They emerge in spring with a reddish hue, turn green in summer, and change to purple-red or orange-yellow in fall. Its flowers are small, white or creamy, and arranged in flat-topped clusters that bloom in late spring to early summer. Its fruits are oval drupes, about 1/4 inch long, and bright red, appearing in late summer to early fall. Its branches are slender, reddish-brown, and often grow in a zigzag pattern, creating a broad and irregular crown.
Light requirements
Cornus asperifolia drummondii, commonly known as Roughleaf Dogwood, prefers a partially shaded area. The plant requires at least four hours of sunlight to grow and thrive, but extended exposure to direct sunlight can harm the plant.
Temperature
The Roughleaf Dogwood requires a cold environment to grow healthy. The temperature range should be between 40-70 degrees Fahrenheit. This temperature range creates a suitable environment for the plant.
Soil requirements
The Cornus asperifolia drummondii thrives in well-drained soil. The soil should be moist, fertile, and acidic. This type of soil composition provides a conducive environment for the growth of the Roughleaf Dogwood. The plant can grow in different soil types, including sandy, clay loam, and loamy soil. However, the soil should not be soggy or waterlogged since it can cause root rot and affect the plant's growth.
Cultivation Method
Cornus asperifolia drummondii, commonly known as Roughleaf Dogwood, is a deciduous shrub that belongs to the Cornaceae family. It is native to North America and can grow up to 8 feet tall and wide. The plant thrives in USDA hardiness zones 3-8 and prefers sunny to partially shaded locations.
For cultivation, you need to select a site that can accommodate the plant’s mature size and good soil drainage. Add organic matter to the soil to enhance soil nutrients, and loosen the soil to ensure good root penetration. Plant the shrub in early spring or fall, and ensure it has adequate space to spread.
Watering Needs
Cornus asperifolia drummondii requires moderate watering during its growth period. The shrub should receive an inch of water every week, whether through irrigation or natural rainfall. Ensure the soil remains moist but not waterlogged, as excess moisture can promote root rot.
Avoid watering the plant from overhead, as this can promote fungal growth and leaf diseases. Instead, water the plant at its base and apply mulch around the plant to retain moisture and prevent evaporation from the soil.
Fertilization
Fertilizing Cornus asperifolia drummondii is not necessary, as the plant has moderate growth and can obtain nutrients from the soil. However, if you need to supplement the shrub’s growth, apply a balanced fertilizer during the plant’s early growth stages. Use organic fertilizers such as compost tea or seaweed extracts, as they release nutrients slowly and promote healthy soil microbial activity.
Pruning
Cornus asperifolia drummondii requires minimal pruning, and you can remove any unwanted shoots or damaged branches in late winter when the plant is dormant. Pruning can promote dense shrub growth and encourage blooming. However, avoid excessive pruning, as this can reduce the plant’s blooming and growth potential.
When pruning, use sharp and sterilized pruning tools, and always cut at a 45-degree angle facing away from the plant’s center. You can also train the shrub to assume a particular shape by cutting branches selectively. However, keep in mind that the natural shape of the shrub is often the best and most appealing.
Propagation of Cornus Asperifolia Drummondii
The plant Cornus Asperifolia Drummondii is a beautiful shrub with white flowers and glossy green leaves. It is commonly grown in gardens and landscapes because of its attractive appearance. The plant can be propagated through various methods, including seed propagation, cutting propagation, and layering propagation.
Seed Propagation
The seed propagation method of Cornus Asperifolia Drummondii is relatively easy and can be done in spring or fall. You should collect the seeds from the plant in the fall and plant them immediately or store them in a cool, dry place until spring. Before planting, you should soak the seeds in water for about 24 hours to increase germination rates.
Once the seeds are prepared, plant them in moist and well-draining soil. Keep the soil moist and warm, and your seeds should germinate in about two to four weeks. Seed propagation is ideal for producing a large number of plants, but it is not always reliable due to variations in genetic traits of plants propagated by seed.
Cutting Propagation
Cutting propagation is another propagation method that can be used for Cornus Asperifolia Drummondii. You should select cuttings from healthy and disease-free plants in late spring or early summer. The cuttings should be about 6-8 inches long, and you should remove the leaves from the bottom half of the stem.
After preparing the cuttings, dip them in rooting hormone and plant them in a well-draining potting mix. Place the pot in a warm and bright location, and keep the soil moist. Over time, the cuttings will produce roots and new growth, and they will be ready to be transplanted into their permanent location.
Layering Propagation
The layering propagation method is ideal for plants that have low rooting success, such as Cornus Asperifolia Drummondii. This method allows the plant to produce roots while still attached to the parent plant.
For layering propagation, select a healthy branch of the parent plant and bend it down to the soil level. Create a small wound on the branch where it touches the soil, then cover the area with soil or rooting hormone. Secure the branch to the ground using a U-shaped wire.
Over time, the branch will produce roots and can be removed from the parent plant and transplanted into its permanent location.
Whichever method of propagation you choose, make sure to take proper care of the new plants to ensure they grow into healthy and beautiful shrubs.
