HOW TO PLANT ASCLEPIAS SEEDS Plant seeds 1/2-1 inch deep into the soil. When grown indoors, transplant into the garden 18-24 inches apart for best results. HOW TO CARE FOR ASCLEPIAS Asclepias is a low-maintenance plant that can live for several years if planted in the proper environment and will come back from a strong taproot every Spring. Asclepias will also readily spread itself via seeds in the late fall, but this can be controlled simply by removing all seed pods in the early fall before they release. Asclepias is a popular butterfly attractor, particularly of the Monarch Butterfly; as long as the plant is healthy, it will readily flower throughout the summer. Fertilization is not necessary. Putting mulch around each plant will reduce competition from weeds or other unwanted plants.
