Light conditions
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. thrives in full sun to partial shade. It requires a minimum of six hours of direct sunlight each day. In areas with hot summer climates, it prefers partial shade to prevent stress.
Temperature requirements
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. is a cold-hardy shrub and can tolerate extremely low temperatures. The ideal temperature range for its growth is between -10°C and 30°C. During the winter months, the plant goes into dormancy, and its shoots die back to the ground level. This plant can resist drought, but prolonged dry periods can affect its growth and quality.
Soil requirements
The ideal soil for Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. is well-drained, slightly acidic, and rich in organic matter. It can grow in various soils, including sandy, loamy, and clay ones. The plant requires regular watering, but the soil should not be waterlogged. Applying a layer of mulch around the plant root zone can help retain soil moisture and keep the soil cool during warm weather.
Cultivation Methods
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss., commonly known as blueberry willow, is a deciduous shrub that belongs to the willow family. It can grow up to a height of 5-7 feet and requires full sun to partial shade to thrive.
The plant prefers well-drained soils that are moist and rich in organic matter. It can tolerate a wide range of soil pH levels and can adapt to a variety of soil types, including sandy soils, loamy soils, and clay soils.
Blueberry willow is hardy in USDA zones 3-6 and can be propagated through seeds or stem cuttings. Young plants need to be watered regularly until they establish roots and are capable of sourcing water from the soil.
Watering Needs
Blueberry willow requires moderate watering during the growing season, especially during hot and dry periods. It is essential to water the plant deeply once or twice a week, depending on the weather conditions and soil type. The soil must be allowed to dry slightly between watering to prevent waterlogging, which may lead to root rot.
During winter, the plant goes dormant and requires minimal watering. The soil should be kept slightly moist to prevent dehydration.
Fertilization
Blueberry willow does not require frequent fertilization, but it can benefit from occasional feeding, especially during the growing season. A balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium can be applied in early spring before new growth appears. Avoid excessive fertilization, as it may stimulate excessive vegetative growth and reduce flower and fruit production.
Pruning
Pruning is an essential aspect of blueberry willow's care and should be done annually to maintain its shape and size. It is best to prune the plant during winter when it is dormant and its leaves have fallen off. Dead, diseased, or damaged branches should be pruned to prevent the spread of disease and pests. Crossing branches and suckers should also be removed to promote good air circulation and light penetration.
Blueberry willow can be shaped into a single-stemmed or multi-stemmed shrub depending on the desired look. It can also be pruned into a hedge or topiary form.
Propagation of Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss.
Propagation of Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. can be done through two main methods: seed propagation and vegetative propagation.
Seed Propagation
Seeds of Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. can be directly sown into the soil in fall or early spring. Before sowing, the seeds should be stratified for a period to break their dormancy. Stratification can be done by mixing the seeds with moist sand or peat moss and keeping them in the refrigerator for a few weeks. The seeds should be sown at a depth of 1/8 inch and kept moist until germination, which usually occurs within 2-4 weeks. Seedlings should be transplanted to their permanent location after they have developed several sets of leaves.
Vegetative Propagation
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. can also be propagated through various vegetative methods, such as cutting, layering, and grafting.
Softwood Cuttings: Softwood cuttings of Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. can be taken in late spring or early summer, when the new growth is still pliable. Cuttings should be about 4-6 inches long and have at least two nodes. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone before being inserted into a well-draining propagation mix. Cuttings should be kept moist and in a shaded location until they begin to root, usually in 4-6 weeks. After rooting, they can be transplanted to their permanent location.
Layering: Layering is another method of propagating Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. This can be done in spring or fall. A low-growing branch of the plant is selected and bent to the ground. The bark is lightly scraped where it contacts the soil, and the branch is held in place with a U-shaped wire or a small rock. The branch should be watered regularly, and roots will form at the point of contact with the soil. After several months, the branch can be separated from the main plant and transplanted to a new location.
Grafting: Grafting is a more difficult method of propagation, but it is commonly used in commercial settings. The desired cultivar is grafted onto a rootstock of a closely related plant species. Grafting can be done in the spring or fall when the plant is actively growing. This method requires skill and knowledge of grafting techniques.
Disease Management
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. is susceptible to various plant diseases. Below are the common ones.
Cytospora Canker
Cytospora canker is a fungal infection that affects the bark of susceptible plants. It causes cankers, or sunken dead areas, on the branches and trunks. The disease can lead to the death of the affected stems if not controlled. To manage this disease, ensure proper pruning and sanitation. Remove any infected limbs, and dispose of them away from the plant. Avoid injuring the bark during planting or maintenance.
Willow Scab
Willow scab, caused by the fungus Venturia saliciperda, causes dark spots on the leaves of the plant. Over time, the spots enlarge, and the leaves curl and fall prematurely. To manage this disease, ensure proper pruning and sanitation. Remove any infected leaves from the plant and dispose of them where the spores can't spread. Proper spacing of the plant and providing enough air circulation can also help manage willow scab. Fungicides may also control this disease.
Black Spot
Black spot, caused by the fungus Marssonina salicicola, creates black, circular spots on the leaves. It can affect the appearance of the plant and cause defoliation. Proper sanitation, such as removing and destroying infected leaves, can be helpful. Fungicides can also be applied to control the disease. Proper plant spacing and enough air circulation can also help with disease prevention.
Pest Management
Salix novae-angliae Anderss. var. myrtillifolia (Anderss.) Anderss. is also vulnerable to pests, which can cause damage to the plant. Here are common pests to watch out for.
Willow Sawfly
The willow sawfly feeds on the leaves of the plant, leading to defoliation. Control measures include removing the larvae by hand or using a strong blast of water to dislodge them. Applying insecticides can also help control the pest.
Borers
Borers are insects that chew through the bark or wood of the plant. This can cause damage or lead to the death of the affected parts of the plant. Preventative measures include regular plant check-ups for signs of infestation and ensuring the plant is healthy enough to withstand attacks. If a borer infestation is identified, removing and destroying the affected areas can control the pest.
