Question: Hi. I recently received 6 packets from you of Butterfly milkweed. Could you provide some advice on planting? I have a small flower garden ( full sun,) as well as 15 acres of various prairie plants and grasses. Began as all switchgrass but I am slowly planting more and more grasses and forbs. Thanks. Stan
Response: Stan, you may start the seeds indoors after you have moist stratified them. Place the seeds in a zip lock back mixed with moist vermiculite. Leave them in a refrigerator for 30 days. Remove and plant in open flats or small pots with sterile soil medium at a depth of 1/8th to 1/4th inch. They must receive considerable light and warmth to adequately develop. Once they have started to form the white root, they can be transplanted to your garden or field. Keep the competition down from weeds and other plants. They prefer well drained to excessively drained soils in full sun. They do well in rocky poor soils with maximum exposure to the sun and wind. If you want to do a dormant seeding, you may spread the seed now or anytime the ground is exposed. Make sure your seeds are not on frozen ground as they may wash away. Wait until the ground thaws and spread your seed but only lightly cover with a sprinkling of soil or compost no deeper than 1/8 to 1/4 inch. Nature can then freeze and thaw offering the best stratification. Once plants are mature, you must be very careful when you attempt to transplant as the roots are very massive and at least 90% of the roots should be dug with plant and immediately transplanted. You should start seeing blooms the second year and thereafter the plants will grow much stronger and have many blooms in the following years. If your plants, for some reason die or disappear the following year after planting, they are probably in a poorly adaptable site for this species.
