Propagation of Solidago aestivalis Bickn.
There are several methods of propagation for Solidago aestivalis Bickn., including seed propagation, vegetative propagation, and division.
Seed propagation
Seed propagation is the most common method of propagating Solidago aestivalis Bickn. Seeds should be collected and sown in the fall, as the plant is a fall bloomer. The seeds should be sown at a depth of 1/8 inch in well-draining soil. Germination should occur within 10 to 30 days. The seedlings should be transplanted to their permanent location in the spring.
Vegetative propagation
Vegetative propagation of Solidago aestivalis Bickn. is done by taking stem cuttings. Cuttings should be taken in the spring, and should be 3 to 4 inches long. Remove the lower leaves on the cuttings and dip the cuttings in rooting hormone, then place them in well-draining soil. Place the container in a warm, bright location, but out of direct sun. Keep the soil moist, but not waterlogged. Roots should develop within 4 to 6 weeks. Once roots have formed, the new plant can be transplanted to its permanent location.
Division
Division is best done in the spring when the plant is just beginning to emerge from dormancy. Dig up the entire plant and separate the root clumps. Replant the separated clumps in their permanent location, making sure to water them well.
