Propagation of Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid.
Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid. can be propagated through various methods, including:
Seed Propagation:
Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid. can be propagated through seeds. However, it is not a reliable method, as seeds have a low germination rate. Collect the mature dried seeds in the fall and sow them right away or in spring after a cold-stratification period between 30-90 days.
Cuttings Propagation:
Cuttings of Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid. can be rooted easily when treated with rooting hormone and planted in moist soil in early summer or late fall. The cuttings should be taken from the current year's growth when the plant is dormant and are around 15cm to 25cm long. The lower leaves should be removed, and the stem should be cut cleanly below the first or second bud.
Division Propagation:
Division is another method of propagating Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid. Divide the mature plant in early spring before the new growth begins. When dividing, cut the crown into sections with roots and replant in fertile soil.
Overall, propagating Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid. through cuttings or division is the fastest and the most reliable method of propagation to produce plants that are genetically identical to the parent plant.
Disease and Pest Management for Salix barclayi Anderss. var. angustifolia (Anderss.) Anderss. ex Schneid.

Common Diseases of Salix barclayi Anderss. var. angustifolia
1. Willow Scab: Willow scab is a fungal disease that affects the leaves, stems, and fruits of Barclay's willow. It causes dark brown or black lesions on the leaves and stems, which can lead to defoliation and stunted growth. The disease spreads by splashing rainwater and can be prevented by providing good air circulation and avoiding overhead watering. Infected plant debris should be promptly removed and destroyed. Fungicides can also be used to manage the disease.
2. Willow Blight: Willow blight is a bacterial disease that causes cankers on the bark and branches of the tree. It can result in wilting, dieback, and death of the plant. The disease can be controlled by pruning the infected branches and applying copper fungicides.
3. Leaf Spot: Leaf spot is a fungal disease that causes small, circular spots on the leaves of the Barclay's willow. The leaves may turn yellow or brown and drop prematurely. The disease can be prevented by providing good air circulation, avoiding overhead watering, and removing infected plant debris. Fungicides can also be used to manage the disease.
Common Pests of Salix barclayi Anderss. var. angustifolia
1. Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. They can cause curling and deformation of the leaves, and the secretion of honeydew can attract other pests. The pests can be removed from the plant by using a strong jet of water or by applying insecticidal soap or neem oil.
2. Willow Leaf Beetles: Willow leaf beetles are small, shiny beetles that feed on the foliage of the Barclay's willow. The larvae can skeletonize the leaves, and the adults can cause defoliation. The pests can be managed by handpicking the adults and larvae, or by applying insecticidal soap or neem oil.
3. Scale Insects: Scale insects are small, immobile pests that attach themselves to the bark and leaves of the plant. They can cause yellowing, wilting, and death of the plant. The pests can be removed by using a soft brush or by applying horticultural oil.
It is essential to monitor the Barclay's willow regularly for signs of disease and pests and to take appropriate measures promptly. Proper care and management can ensure the health and longevity of the plant, allowing it to thrive and add beauty to the landscape.
