Time to Plant
Common Milkweed isn't too choosy about soil. Unless your soil is totally lacking in nutrients, the seeds should germinate as long as the earth is loose and kept damp. The plants will only be that much happier if you prepare the bed first with some rich compost material.
Once you have chosen your spot, you need only scratch the seeds into the loosened soil. One
pod has hundreds of seeds so if you have a pod, be sure to break it open and spread the contents-don't plant the pod as one giant seed!
If you sow in the fall, you're done. Just wait for the tiny plants to emerge in the spring. If you have
an exceptionally dry spell, water the area to keep the seeds moist until they germinate.
If you sow your seeds in the spring after at least 6 weeks in your refrigerator, keep the area
moist until the seedlings emerge.
When your milkweed plants start to break the surface, keep them watered until they are established. Mature plants nearly take care of themselves and need little tending.
