Aster ericoides L. var. prostratus does not require frequent pruning, but some light pruning can help promote a fuller, bushier plant. Dead or damaged stems should be removed promptly to prevent the spread of disease.
Pruning can also be used to control the plant's height and shape. For a more compact plant, pinch back the stems in early spring when they are about 4 to 6 inches tall.
In general, pruning should be done in early spring or after the plant has finished flowering in late fall.
Propagation of Aster ericoides L. var. prostratus (Kuntze) Blake
Aster ericoides L. var. prostratus (also known as trailing aster) is a native North American plant that is often found in rocky or sandy soils. It is a low-growing, spreading plant that produces masses of small, white flowers in the fall. There are several propagation methods that can be used to replicate this plant.
Seed propagation
One of the easiest ways to propagate trailing aster is through seed propagation. Collect the seeds after the bloom period in the fall and store in a cool, dry place until ready for planting in the spring. Before planting, stratify the seeds by placing them in a moist, cool place for 2-4 weeks to stimulate germination. Once stratified, plant the seeds in a well-draining soil mix, covering them lightly with soil. Keep the soil moist but not waterlogged and place the tray in a warm, sunny spot. Germination can take anywhere from 1-3 weeks.
Division
Trailing aster can also be propagated through division. This method is best done in the spring or fall, when the plant is not in active growth. Simply dig up the plant and use a sharp knife to divide the root ball into sections. Each section should have at least one healthy stem and a portion of the root system. Replant the new divisions in well-draining soil, keep the soil moist, and place the plant in a sunny spot.
Cuttings
A third method of propagation is through stem cuttings. Take stem cuttings from the trailing aster plant in the summer, choosing non-flowering stems. The cuttings should be approximately 4-6 inches long. Remove the lower leaves on the stem and dip the cut end in rooting hormone. Plant the cutting in a well-draining soil mix, lightly cover with soil, and water well. Keep the soil moist and place the plant in an area with bright, indirect light. The cutting should root in about 3-4 weeks.
With these propagation methods, you can easily expand your collection of trailing aster plants and enjoy their lovely fall blooms year after year.
