This plant prefers full sun to partial shade and well-drained soil. The planting location should provide enough room for the tree's roots to develop.
It is best to plant the tree in the fall or early spring before the growing season begins. The planting hole should be two to three times the size of the root ball. The root ball should be positioned to sit above the soil line, and the hole should be filled with soil and gently packed. The tree should be watered thoroughly after planting.
Watering needs
Salix longifolia Muhl. var. pedicellata Anderss. prefers moist soil but can handle drier conditions once established. The tree should be watered during the growing season, especially during dry spells. However, overwatering should be avoided as it can lead to root rot.
During the first year after planting, the tree should be watered once a week unless rainfall is sufficient to keep the soil moist. After the first year, the tree may not need regular watering except during extended dry periods.
Fertilization
Salix longifolia Muhl. var. pedicellata Anderss. does not typically require fertilizer if planted in nutrient-rich soil. However, if the soil is lacking in nutrients, fertilizer may be applied in the spring. A slow-release fertilizer should be used, and it should be applied according to the manufacturer's instructions.
It is essential not to over-fertilize as it can damage the tree's roots. If the tree is showing signs of nutrient deficiency, a soil test can be conducted to determine which nutrients are lacking. Fertilizer can then be applied accordingly.
Pruning
Pruning is essential to maintain the health and shape of Salix longifolia Muhl. var. pedicellata Anderss. The tree should be pruned in late winter before new growth begins. Dead, diseased, or broken branches should be removed first, followed by any branches that are crossing or rubbing together.
The tree should be pruned to encourage a central leader and a balanced shape. This will prevent the tree from becoming too dense and reduce the risk of branch failure. Pruning shears or a pruning saw can be used to remove branches. Care should be taken to sterilize tools between cuts to prevent the spread of disease.

It is hardy and adaptable to a variety of growing conditions, making it a popular choice for landscaping and erosion control. Propagation of Salix longifolia Muhl. var. pedicellata Anderss. can be accomplished through several methods.
Sowing Seeds
One of the most common propagation methods for Salix longifolia Muhl. var. pedicellata Anderss. is through sowing seeds. The seeds should be collected in the late summer or early fall when they are fully mature. They can be stored in a cool, dry place until planting in the spring. The seeds should be sown in well-draining soil that has been amended with organic matter. Cover the seeds with a thin layer of soil, and keep the soil moist but not waterlogged. Germination should occur within a couple of weeks.
Cutting Propagation
Another propagation method for Salix longifolia Muhl. var. pedicellata Anderss. is through cutting propagation. This involves taking cuttings from the parent plant and rooting them in a growing medium. The best time to take cuttings is in the late fall or early winter when the plant is dormant. Cuttings should be taken from young, healthy wood and should be about 8-10 inches long. Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone. Plant the cutting in a well-draining growing medium, such as sand or perlite, and keep it moist. The cutting should root within a few weeks.
Division
Salix longifolia Muhl. var. pedicellata Anderss. can also be propagated through division. This involves dividing the parent plant into smaller sections and planting them separately. The best time to divide the plant is in the early spring before new growth emerges. Dig up the parent plant and use a sharp tool to divide it into smaller sections, making sure each section has roots attached. Replant the sections in well-draining soil amended with organic matter and keep the soil moist.
Overall, Salix longifolia Muhl. var. pedicellata Anderss. is a hardy and adaptable plant that can be propagated through sowing seeds, cutting propagation, and division. With proper care and attention, these propagation methods can be successful in producing healthy new plants.
Disease and Pest Management for Salix longifolia Muhl. var. pedicellata Anderss.
Salix longifolia Muhl. var. pedicellata Anderss., commonly known as longleaf willow, is a native shrub in the United States often used for its ornamental value and as a source of wood. Like other plant species, longleaf willow is susceptible to various diseases and pests that can affect its growth and productivity. Proper disease and pest management practices are essential for maintaining healthy and robust longleaf willow populations.
Common Diseases
Longleaf willow is prone to several diseases that can significantly reduce its growth and yield. Some of the commonly known diseases that affect longleaf willow include:
Willow scab
Willow scab is a fungal disease that attacks the leaves, twigs, and branches of longleaf willow. The symptoms of willow scab include the formation of small, sunken, and grayish-green lesions on the leaves, which later turn brown or black.
