Propagation Methods for Salix dodgeana Rydb.
Salix dodgeana Rydb. commonly known as Dodge Willow or Geyer Willow is a deciduous shrub that is native to western North America. The shrub is commonly used as an ornamental plant due to its beautiful flowers and leaves. If you're looking to propagate this plant, you have a few different options to choose from.
Seed Propagation
The simplest way to propagate Salix dodgeana Rydb. is by seed. Seeds can be collected from the plant directly after the flowers have faded in the spring. The seeds require a period of cold stratification to break dormancy. This can be achieved by placing them in a moist substrate, such as peat moss, and storing them in a refrigerator for several weeks. Once stratified, the seeds can be sown in pots or directly in the ground. Keep the soil consistently moist until the seedlings emerge.
Cuttings Propagation
Another way to propagate Salix dodgeana Rydb. is through cuttings. Hardwood cuttings can be taken from the plant in the fall or winter when the plant is dormant. Cuttings should be around 8-10 inches long and should be treated with a rooting hormone to encourage root growth. They can then be placed in a soil medium such as sand or perlite and kept moist. The cuttings should begin to root in approximately four to eight weeks.
Division Propagation
Dividing mature plants is also an option for propagating Salix dodgeana Rydb.. It is best done in the spring or fall when the plant is dormant. Dig up the plant and divide the root system into sections using a sharp, sterilized knife. Replant each section in a prepared soil mixture and keep the soil moist until new growth appears.
