Title: Moving milkweed to another location in Maine, NY
Answered by: Barbara Medford

QUESTION:

I live in up-state New York. I have a 'patch' of milkweed growing where I don't really want it to grow - but have left it because the butterflies and bees love it. I would like it to grow in my back field - how can I get it started there before I start getting rid of it in my door yard?

ANSWER:

There are 41 members of the Asclepias (milkweed) native to North America, 13 to New York State. In the area of Maine, New York, south-central New York State, USDA Hardiness Zone 5a to 5b, there are 5 shown in the USDA Plant Profiles as being native. We feel that the instructions for one milkweed would be pretty similar to the others, but we are going to list that 5 native to your area, and look at propagation instructions for them to see what would be appropriate. Follow each plant link to the webpage on that particular plant in our Native Plant Database to find out more about that species.

Members of Asclepias Genus Native to Broome Co., New York Area:

Asclepias exaltata (poke milkweed)

Asclepias incarnata (swamp milkweed)

Asclepias quadrifolia (fourleaf milkweed)

Asclepias syriaca (common milkweed)

Asclepias tuberosa (butterfly milkweed)

From information in our Native Plant Database:

"The name milkweed refers to the milky white sap, which contains bitter chemicals to protect the plants from predators. A few insects are immune to these poisons and accumulate them in their bodies, protecting themselves from their own predators. Monarch butterflies cannot complete their life cycles without milkweed."

"Propagation Material: Seeds , Root Cuttings
Description: The easiest method of propagation is root cuttings. In the fall, cut the taproot into 2-inch sections and plant each section vertically, keeping the area moist.
Seed Collection: Watch plants closely for seedpods in late summer/early fall. Allow seeds to completely mature before collecting seed to establish new plants in another location. A long pod is produced containing hundreds of seeds with tufts of long, silky hairs (an adaptation for wind dispersal).
Commercially Avail: yes
Maintenance: Needs to be transplanted carefully and requires good drainage. It takes 2 – 3 years before Asclepias  produces its flowers which appear in 2 – 3 inch clusters. Once established, it lasts for years, becoming thicker each year."

It would appear that under any circumstances, you are going to have to wait until Fall to transfer your milkweed to another part of your garden, whether by seed or by division.
