Propagation of Rumex occidentalis S. Wats. var. labradoricus (Rech. f.) Lepage
Rumex occidentalis S. Wats. var. labradoricus (Rech. f.) Lepage, commonly known as Western dock, is a perennial plant that belongs to the family Polygonaceae. It is native to North America, particularly in the western regions. Western dock is a hardy plant that can grow in a variety of soil types, including sandy or rocky soils.
Seed Propagation
Western dock can be propagated from seeds. Seeds should be sown directly into the soil in early spring or fall. It’s important to ensure that seeds have adequate moisture, so keep soil well watered until seedlings emerge, usually within 2-3 weeks. Germination rates can be improved by soaking the seeds in water for 24 hours before planting.
Seedlings should be thinned out to allow adequate space and nutrients for growth. Western dock tends to grow tall and spindly, so it may require staking to prevent it from bending or breaking.
Vegetative Propagation
Rumex occidentalis S. Wats. var. labradoricus (Rech. f.) Lepage can also be propagated vegetatively, through division or cuttings. Division involves separating the roots of an established plant and planting them as individual units. Spring or early fall is the best time for division.
Root cuttings taken in early spring can also be used to propagate western dock. Cuttings should be about 6 inches long and rooted in potting soil or directly in the garden bed. Keep the cuttings moist and in a warm environment until roots have formed and new shoots emerge, which usually takes within 3-4 weeks.
Overall, Western dock is an easy-to-propagate plant that can be grown in USDA zones 3-9. Regardless of the method of propagation used, it’s important to keep the soil well drained in wet weather conditions and also to ensure that the plants receive adequate sunlight and water.
