Growth Conditions for Salix myricoides Muhl. var. albovestita (Ball) Dorn
Salix myricoides Muhl. var. albovestita, commonly known as the White-haired Willow, prefers to grow in moist or wet soil along streams, creeks, and other water sources. They are hardy in USDA zones 5a to 8b, and can grow up to 20 feet tall and 15 feet wide.
Light Requirements
The White-haired Willow requires full sun to partial shade to thrive. They can tolerate some shade from other plants or trees, but too much shade can negatively affect their growth and overall health.
Temperature Requirements
The White-haired Willow is a hardy plant that can tolerate cold temperatures in winter, but prefers warm temperatures during the growing season. They can tolerate temperatures as low as -20°F (-29°C) and as high as 100°F (38°C), making them suitable for most temperate climates.
Soil Requirements
The White-haired Willow prefers moist and well-drained soil that is rich in organic matter. They can tolerate a wide range of soil types, but prefer slightly acidic to neutral soil with a pH between 6.0 and 7.5. They are adapted to growing in wet and poorly drained soil, making them ideal for areas near water sources.
To promote healthy growth, it is important to keep the soil consistently moist, but not waterlogged. Watering should be regular, especially during dry periods. Adding a layer of mulch around the base of the plant can help retain moisture and regulate soil temperature.
Cultivation methods
Salix myricoides Muhl. var. albovestita (Ball) Dorn, commonly known as the gray or white willow, is a deciduous shrub that can grow up to 8-10 feet tall. It thrives in USDA hardiness zones 3 to 7 and prefers full sun to partial shade. To cultivate this plant, you need to prepare a well-draining soil rich in organic matter. The planting hole should be two to three times wider than the root ball and deep enough to accommodate it comfortably. The plant's root collar should be level with the soil surface. After planting, water the shrub thoroughly, and add a 2-3 inch layer of mulch around the plant base. Mulch helps to keep the soil moist, reduce weed growth, and maintain the soil temperature.Watering needs
Salix myricoides Muhl. var. albovestita enjoys moist soil but is susceptible to root rot if the soil is soggy. It is best to water the plant deeply once or twice a week, depending on the weather. To ensure the plant receives adequate water, water deeply and allow the soil to dry to about 2 inches before watering again. In hot and dry climates, you may need to increase the frequency of watering.Fertilization
Salix myricoides Muhl. var. albovestita doesn't require much fertilization, and too much can lead to excessive growth and weak stems. When planting, mix some compost or well-rotted manure into the soil. You can also top dress the soil with a slow-release fertilizer or apply a liquid fertilizer once in spring. Avoid fertilizing after mid-summer to prevent the plant from growing too much before winter.Pruning
Pruning Salix myricoides Muhl. var. albovestita is essential to keep its growth in check and maintain the shrub's health and shape. You should prune the plant when it is dormant in late winter or early spring. Start by cutting out any dead, diseased, or damaged wood. You can also remove any crossing or rubbing branches to improve airflow and prevent disease. Cut back the new growth to a third of its length to encourage branching and bushier growth. In conclusion, Salix myricoides Muhl. var. albovestita is a hardy and easy-to-care-for plant. With proper cultivation, watering, fertilization, and pruning, you can enjoy its beautiful foliage and delicate blooms year-round.Propagation of Salix myricoides Muhl. var. albovestita (Ball) Dorn
Propagation of Salix myricoides Muhl. var. albovestita (Ball) Dorn can be done through several methods. These include:
Seed Propagation
Seeds are a common way of propagating Salix myricoides Muhl. var. albovestita (Ball) Dorn. The seeds must be stratified for 3-4 months before sowing in either fall or spring. The seedlings will start to emerge 14-21 days after sowing.
Softwood Cuttings
Softwood cuttings taken from Salix myricoides Muhl. var. albovestita (Ball) Dorn in late spring or early summer can be rooted easily under mist. The cuttings should be 3-6 inches in length and have at least two nodes. They should be dipped in rooting hormone before being planted in a sandy medium and placed under mist until they have rooted.
Hardwood Cuttings
Hardwood cuttings are taken in late fall or winter and should be stored in a moist medium until planted in the early spring. Cuttings should be 8-12 inches long and have at least two nodes. They should be dipped in rooting hormone and planted in a well-draining medium. Hardwood cuttings may take longer to root than softwood cuttings.
Coppicing
Coppicing, which involves cutting the shrub back to near ground level, is a method used for propagating Salix myricoides Muhl. var. albovestita (Ball) Dorn. This method results in multiple shoots emerging from the cut stems. These shoots can be used to propagate new shrubs by cutting them and planting them in desired locations.
Disease and Pest Management for Salix myricoides Muhl. var. albovestita
Salix myricoides Muhl. var. albovestita, commonly known as white-woolly willow, is a relatively disease-resistant and pest-resistant plant. However, some diseases and pests can still cause damage. Here are some common ones and their management techniques:
Diseases
Cytospora Canker: This fungal disease causes sunken, discolored areas on the bark, and can lead to wilting and death of branches. Prune and destroy affected branches and improve overall plant health through proper watering and fertilization.
Willow Scab: This fungal disease causes black, scabby lesions on leaves and can defoliate the plant. Plant disease-resistant varieties and improve air circulation around the tree by proper pruning.
Powdery Mildew: This fungal disease causes a white powdery coating on leaves, which can stunt growth and weaken the plant. Avoid overhead watering and improve air circulation around the plant.
Pests
Aphids: These small insects can cause leaf distortion and yellowing. Use insecticidal soap or a strong blast of water to remove them.
Willow Leaf Beetle: These beetles can defoliate the plant and weaken it. Handpick and destroy the beetles and their eggs.
Sawflies: These insects can also defoliate the plant. Handpick and destroy them or use a biological control like Bacillus thuringiensis.
