Propagation of Salix arctica Pallas var. araioclada (Schneid.) Raup
Salix arctica Pallas var. araioclada (Schneid.) Raup plant is a well-known Arctic shrub, commonly known as Arctic willow, that grows in damp and cold conditions. This plant is easily propagated through various methods that include; vegetative propagation, seed propagation, and cuttings propagation.
Vegetative Propagation
Vegetative propagation is the easiest and most common way of propagating Salix arctica Pallas var. araioclada (Schneid.) Raup plant. This method involves taking stem cuttings, rhizomes, or suckers from the parent plant to produce new plants. The cuttings are then planted in soil or rooting hormone and kept in an environment with high humidity.
Seed Propagation
Seed propagation is one of the natural ways Salix arctica Pallas var. araioclada (Schneid.) Raup plant reproduce. To propagate the plant through this method, you have to collect the seeds during the blooming period and then plant them in seed trays or containers filled with soil or sand with good drainage. The seeds should then be covered and kept in a cold environment (below 4?C) for 2-3 months to facilitate stratification. Once stratification is achieved, the seeds are transferred to a warmer environment for germination.
Cuttings Propagation
Cuttings propagation is similar to vegetative propagation but involves the use of stem cuttings with the intention of rooting them in a rooting hormone. The process includes the removal of hardened stem cuttings making sure the cuttings have at least two nodes and are about 10-15 cm in length. The cuttings should then be treated with rooting hormone and placed in a rooting medium like sand or perlite, ensuring that the medium remains moist. The plants should be kept in a warm location (20-23°C) with plenty of light and not exposed to direct sunlight. Roots should start to appear in 3-4 weeks. Once the roots are 1.5-2 inches in length, they can be transplanted to larger containers or outdoors.
