Salix arctica Pallas var. petraea (Anderss.) Bebb, commonly known as Arctic Willow, is a small shrub that grows up to 1 meter in height. It is a woody plant that is native to tundras and rocky slopes in the Arctic regions of North America. Propagation of Salix arctica Pallas var. petraea (Anderss.) Bebb can be done through various methods, including seed germination, stem cuttings, and division.
Seed germination
The Arctic Willow can be propagated by planting seeds in a well-draining soil mix that is kept moist. The seeds should be stratified in the fridge for about a month before planting to help break the dormancy. Sow the seeds on the surface of the soil and cover them lightly with a thin layer of sand. Keep the soil humid by covering the container with plastic wrap. Germination can take several weeks, and the container should be kept in a bright location away from direct sunlight. Once the seedlings have grown about 3 inches tall, they can be transplanted into larger pots or directly into your garden.
Stem cuttings
Propagation of Salix arctica Pallas var. petraea (Anderss.) Bebb can also be done through stem cuttings. Cut a stem of about 4 to 6 inches in length from a healthy Arctic Willow shrub during the growing season. Remove the lower leaves and any flowers or buds from the stem. Dip the cut end of the stem in rooting hormone powder, and plant it in a well-draining soil mix. Keep the soil moist and cover the container with plastic wrap to maintain humidity. Place the container in a bright location, away from direct sunlight. The cuttings should root in around 4 to 6 weeks. Once rooted, the plants can be transplanted into larger pots or your garden.
Division
Propagation of Salix arctica Pallas var. petraea (Anderss.) Bebb can also be done through division. This method is best done during the fall. Dig out the mature plant from the ground and gently separate the clumps of roots and stems. Replant the separated sections in a well-draining soil mix, and water them well. Place the plants in a bright location, away from direct sunlight. The plants will take several weeks to establish their roots before you can transplant them into larger pots or your garden.
