Propagation of Salix caprea L.
Salix caprea L. commonly known as goat willow or pussy willow is a deciduous shrub/tree belonging to the family Salicaceae. This plant is often propagated for commercial and ornamental purposes. There are mainly two methods of propagating Salix caprea L. namely, vegetative propagation and sexual propagation.
Vegetative Propagation
One of the most common vegetative propagation techniques used for Salix caprea L. is Hardwood Cutting. In this method, semi-hardwood cuttings are taken in late summer or early autumn. The cuttings must be approximately 15-20 cm long and have at least 2-3 buds. The leaves present in the lower half of the cutting must be removed. The cutting is then dipped in rooting hormone and planted in well-drained soil. The cuttings take around 6-8 weeks to root and form new leaves.
The second vegetative propagation method is Softwood Cutting. In this method, softwood cuttings are taken in early summer when the plant is actively growing. The cuttings must be approximately 10-12 cm long and have at least 2-3 buds. The leaves present in the lower half of the cutting should be removed. The cutting is then dipped in rooting hormone and planted in well-drained soil. It takes around 3-4 weeks for the cuttings to root and form new leaves.
Sexual Propagation
The sexual propagation method for Salix caprea L. is through seeds. The seeds are available in large quantities during the late summer months. The seeds must be collected when they are mature. The collected seeds can then be soaked in warm water for 24 hours prior to sowing. The seeds are then sown in well-drained soil and covered with a thin layer of soil. The seeds will germinate within 2-3 weeks.
The young plants that are produced through sexual propagation can be transplanted to a permanent site once they are large enough to handle.
Disease and Pest Management for Salix caprea L.
Salix caprea L. is native to Europe, western Asia, and northern Africa, and it belongs to the family Salicaceae. It is commonly known as goat willow or pussy willow, and it is a deciduous tree or shrub that can grow up to 10 meters tall.
