Where should you not plant milkweed?

Does milkweed come back every year?
These native milkweed are perennials, meaning they come back year after year. Their aerial parts (flower, leaves, stem) die back but their rootstock remains alive throughout the winter. Cut back milkweed stalks in the late fall or winter, after they have produced seed pods and these seeds have had time to mature.
Can I just scatter milkweed seeds?
You can sow milkweed seeds by scattering them on the soil surface 1/4-1/2 inch apart, and then cover them with about 1/4 inch of additional soil. Water the area frequently after planting until plants become established. Many species need to be vernalized (cold treated) before planting.
What month do you plant milkweed?
Ideally, the best time to plant milkweed seeds is in the fall so the cold temperatures and moisture that come with winter stimulate germination. You can also plant milkweed in the springtime.
How invasive is milkweed?
Myth #1: Milkweed is an invasive weed It may have “weed” in the name, but there are over 100 species of milkweed native to the United States and none of them are considered “noxious weeds”.
Why do farmers not like milkweed?
Milkweed has a reputation for encroaching on cropland where it can compete with crops for soil and light. The plant can also create a nuisance on ranchlands, as cattle can be poisoned when poor foraging conditions lead hungry cows to milkweed-concentrated areas as a last resort.
Why is milkweed a problem?
Tropical milkweed becomes a problem when planted in temperate areas where it does not die back in winter. A protozoan parasite of monarch butterflies, Ophryocystis elektroscirrha or OE for short, can travel with monarchs visiting the plants and become deposited on leaves.
Should you plant milkweed in your yard?

Should you cut down milkweed in the fall?
It is recommended to prune the milkweed stalks to about 6 inches in height during the fall and winter months to discourage monarchs from establishing winter-breeding colonies. Cutting back the milkweed will also help to eliminate OE spores that may be present on the plant.
Will milkweed bloom first year from seed?
In general, milkweed may not flower in the first year of growth, because it is investing its resources in growing a strong root system. Also, if there is excess nitrogen in the soil the plant may not flower, so do not fertilize milkweed.

And--what a bonus--milkweed happens to be very deer-resistant. I love to make lists and here's a list help the cause: deer-resistant native perennials, shrubs and trees.
Should I plant milkweed seeds in fall or spring?
Although you can plant Milkweed in the spring after cold stratification and starting seeds indoors, fall is the easier — and more natural — time to plant.
How long until milkweed is fully grown?
Ideally a sturdier stem is better. Cold stratified seeds should germinate and sprout within 10-15 days once planted. In total Milkweed from the day they are cold stratified to growth can take 40 plus days, so be patient!
How many years does it take milkweed to bloom?
A first year Asclepias incarnata plant (Swamp Milkweed) will have to wait another two years before it's blushing vivid pink with nectar-rich flowers. The first year the young milkweed builds its roots.

Most milkweed species do best in full sunlight, so choose an open area with lots of sun. Plant the seedlings 1-2 feet apart. The seedlings should be watered frequently; mulch can be used to help hold in the moisture around the plants.
Is planting milkweed a good idea?
Milkweeds are the required host plants for monarch butterfly caterpillars (female monarchs lay their eggs on milkweeds) and their flowers provide nectar for bees, butterflies, and other beneficial insects. By planting milkweed, you can provide habitat for monarchs and also attract and support pollinators.
Will milkweed take over my yard?
