How to Start Native Milkweed Plants from Simple Stem Cuttings?

July 18 By Tony Gomez

How to Clone Native Milkweed by taking Stem Cuttings
Try Rooting Hormone Powder or Gel

Tropical milkweed cuttings can be started indoors throughout the year, but native milkweed has a smaller window of opportunity…

Summer is a prime time to take native milkweed cuttings for a few compelling reasons:

  • native milkweed plants still have herbaceous, viable stems
  • mid-summer cuttings  will grow roots in plenty of time for fall planting
  • You can keep the cuttings containers outdoors

Here are some milkweed varieties we will attempt to propagate with stem cuttings, but really, you can try this with any variety if you have herbaceous stems available:

Asclepias tuberosa (butterfly weed)

Butterfly Weed Cuttings Plant in Soil
Surprise on one of the Cutting Leaves

Tuberosa is one of the few varieties that can be propagated in both soil and water. We’ve attempted to root other native milkweeds in water, but the stems have always rotted.

For the following varieties (and others not listed) we suggest using the traditional cloning method detailed below:

Asclepias speciosa (showy milkweed)

Ascelpias incarnata (swamp milkweed)

Asclepias incarnata (‘ice ballet’)

Asclepias syriaca (common milkweed)

 

Steps for Taking Native Milkweed Cuttings

1. Use organic peatir?t=monabuttgard 20&l=ur2&o=1 native milkweed or all-purpose potting soil in pots.

1a. An alternative idea is to place cuttings in 2 liter soda bottles to give each cutting optimal growing conditions in their own mini-greenhouse.

2. Mix in perliteir?t=monabuttgard 20&l=ur2&o=1 native milkweed or coarse sand to allow more air to reach the newly forming roots

2. Water soil thoroughly.

3. Insert chopstick/pencil in soil to make holes for placing cuttings.

4. Use a sharp hand prunerir?t=monabuttgard 20&l=ur2&o=1 native milkweed to take cuttings.

5. Take a cutting that has between 3-5 leaf nodes (or is about 4″ long).

6. Pinch off all but the top two pairs of leaves from your cuttings so that water doesn’t evaporate through the leaves…transpiration.

7. Scrape the bottom third of the cutting with a sharp knife.

8. Dip the scraped area in rooting hormone powder. Find several options and customer reviews here:

Rooting Hormone Powderir?t=monabuttgard 20&l=ur2&o=1 native milkweed

9. Place cuttings in holes and secure soil around them.

10. Keep cuttings in an area that receives light, but minimal direct sunlight.

11. Spray soil and leaves daily.

Native Milkweed Cuttings Set Up
Asclepias Tuberosa was the only Native Milkweed to Root in Water

Soil For Cuttings

We’re planting our native milkweed cuttings in an 80/20 mix of perlite to peat moss, which is a more traditional mix for starting stem cuttings than starting  in soil.

Adding sand and/or vermiculite to the mix could also increase your success rate for milkweed cuttings.

In previous seasons, we tried starting milkweed cuttings in potting soil and most of the cuttings rotted because there wasn’t enough oxygen in the soil. If you opt for potting soil as your growing medium, be sure to mix in plenty of perlite…

Alternatively, you could direct planting your cuttings in regular garden soil using rooting hormone powder. We’ve done this successfully with tropical milkweed, but have not tried with other native or non-native varieties.

Results?

Unfortunately, we have not had much success with native milkweed cuttings. Your best chance for cloning is with Asclepias tuberosa. Asclepias incarnata can be easily divided in spring/fall to multiply your milkweed supply.

    I use a lot of cuttings for my cats. After they have eaten all the leaves off I put the stems in a glass with water. Later, I go back and have roots on the stems. They are ready to plant. Great way to get more Milkweed.

      Hi Judy, water propagation works well for tropical milkweed. Do you do this for other species?

    I accidently rooted an accidental broken off a small plant cutting of Butterfly weed (Asclepias tuberosa) in water. It was about 4 inches long and full of small leaves, most of which I left intact as I was using it in a flower arrangement for greens. I’ve now potted it up.

    I had great luck winter sowing Butterfly weed (Asclepias tuberosa) seed.

    I have no problem getting milkweeds to grow by seed —it`s getting them to grow tall that’s the problem—-when they get to about 4 to 6 inches tall I start noticing little tiny monarch catipallars all over them and in 1 or 2 days all the plants are eaten. I actually had to drive over to a local park that has a butterfly garden and cut some of the milkweeds to feed my catapillars who ran out of food . Do I have to build something to cover the plants so they can grow tall enough to accommodate all the catapillars ?

    • Tony Gomez says

      March 26 at 10:10 am

      Hi Ed, I’m going to assume you live in Florida or California? This is a common problem for butterfly gardeners in those regions. Yes, some people cover their plants so they can grow to maturity. I would suggest joining a facebook group to see what specific methods gardeners are utilizing in your region. That should give you some good ideas:

      I live in south GA on the coast. My grandson who is 4 and I have been growing caterpillars since spring, caging a few on plants in gallon pots. He takes them to pre-k so the kids can watch the “hungry” caterpillars grow (we changed out pots of milkweed often) and form chrysalis and then become butterflies. Having enough milkweed was a BIG problem. I must have the tuberosa variety of milkweed because I can root it in water.

      Our problem stemmed from too many Monarch eggs, too many caterpillars and the not enough to eat. We bought one group of plants that had been sprayed with pesticide so that the aphids were non-existent (look for aphids when buying is my new theory). I now have a lot of milkweed but it is leggy and doesn’t send up more shoots from the base. I noticed that the plants who had several caterpillars are the best -probably because of their droppings.

      Our Monarchs must like the coast because we have a steady stream of eggs. The only bad thing is our community sprays for mosquitos and that has had a deadly affect on hatching eggs. If I move the plants with eggs to a cage and indoors we seem to do fine. Educating everyone about symbiosis is key. We put up our first bat house and encourage our native birds.

    I’ve read somewhere to clip the top leaves to create more stalks but have been unsuccessful. Please help.

    • Tony Gomez says

      July 26 at 3:44 pm

      Hi Becky, on mature plants I cut back some of the stalk too…up to a third.

  5. S. Smith says

    May 14 at 12:33 pm

    The photos show cuttings with a couple of leaves on them, and it states to cut all but two leaves. But say you have a milkweed stalk with no leaves at all, or a really long one, with only two leaves at the top. Can you cut the rest of the stalk into 4″ cuttings (though there won’t be any leaves)? Or does the cutting need leaves? Thank you.

    • Tony Gomez says

      May 14 at 3:07 pm

      If you’re rooting tropical mw, you can do all those things. You’d have to experiment for more answers on the native varieties. Other than curassavica and tuberosa, most milkweed species don’t root so easy unless you’re in a greenhouse environment. The most effective propagation technique in our northern region has been:

  6. Dave says

    March 31 at 8:43 pm

    Any updates on native milkweed propagation by cuttings? Btw, someone mentioned layering. I saw a crassavica stem that had been knocked over and buried. New plants sprouted from every node.

    • Tony Gomez says

      April 1 at 10:25 am

      Hi Dave, non-native tropical milkweed is by far the easiest milkweed to propagate. Native milkweed species can be propagated by stem cuttings but need an environment conducive to growing, like in a greenhouse or under a misting system. Our cuttings experiments have been limited to water propagation in cups and with clone buckets, which have not worked for native milkweed. We may try some in our porch this spring, which should provide better cuttings quality and better growing conditions.

    • Kenny says

      May 27 at 5:54 am

      I am having luck with common wm. I used a growth hormone on all of them. About half are working. I have also transplanted some very young antelope horn sprouts that are doing well. Don’t be too hasty in condemming a dead looking MW transplant. It may restart itself.

  7. Teresa says

    I have the Gomphocarpus Physocarpus, or Balloon plant Milkweed. I absolutely love it. I live in Zone 8 and there is a chance it will make it through the winter here, at least if we do not have an unusually cold one. I started this plant indoors from seed last year. I placed the seeds in a damp paper towel for a few days until they had just started germinating and then planted them.
    It is probably too late to do a stem cutting now, but does that work for this variety of milkweed?

    • Tony Gomez says

      October 17 at 8:24 pm

      Hi Teresa, I have only tried rooting it in water, and the cuttings rotted. I did take a cutting of Gomphocarpus fruticosus a few days ago, and will be sure to update that page with the results:

      • Teresa says

        October 19 at 6:19 pm

        I will look for your results later on in the season. I like the Swan plant, too. I am going to cut some of the stems with the largest pods and out them in water and let the pods finish ripening. I probably have. 200 seeds or more now, but since so few people know about this plant, it os a fun one to share seeds from.
        Your website has been the most informative I have found about raising Monarchs and the plants that support them.

        • Tony Gomez says

          October 19 at 6:32 pm

          Hi Teresa, I would let them ripen outdoors…our plants are still outside in Minnesota and just collected some seeds today. good luck!

  8. Judy says

    August 22 at 1:07 pm

    1. I have tuberosa that is growing from seeds. How tall does it need to be to put in the ground?

    2. I cut my tropical down to 6″. Something was eating the each of the leaves to where there wasn’t much of the leaves left. There were very few monarchs coming to my garden. Only found 3-4 caterpillars before the plants were cut. Since then I have not caterpillars. Do you have any idea what I could do. I am at a loss because I have always had really nice MW with many butterflies.

    • Tony Gomez says

      August 23 at 10:37 am

      Hi Judy, you can plant them at any time, but consider waiting until it cools down in late summer/early fall if you’re experiencing hot summer weather. You might consider a protective fence to stop small critters like rabbits from eating your seedlings.

      I don’t know where you’re located, but even if I did it’s impossible to give you a definitely answer why monarchs aren’t visiting your garden. My best advice is to improve your garden while you are waiting, so they won’t want to leave when they come back…good luck!

    Will tropical work in zone 7?

    Although there are Monarchs in the area, we live in a 2 acre area back in the woods and although we get other types of butterflies, we get no Monarchs. I have 10 common milkweed plants, had over 100 seed pods this year, but no monarchs. I tried buying eggs or caterpillars from several sites but nobody had any.

    • Tony Gomez says

      August 16 at 9:16 am

      Hi Bill, I’m in zone 5 and we grow it annually. We actually overwinter a couple plants indoors and then take stem cuttings to start new plants in spring. If you are starting seeds, I recommend starting them early indoors or your plants might not mature and seed. Here’s more info on starting tropical milkweed seeds and cuttings:

    I start cuttings using a powder rooting hormone>>>”Green Light Rooting Hormone”__Home Depot , gardening stores.

    The protocol is 5_ simple steps:

    1. With a knife scrape a several inch area at the bottom area of the stem.

    2. Dip this area in water.

    3. Then dip stem in the powder root Hormone, shake off excess power.

    4. With a pencil punch a hole in the growth medium (potting soil)

    5. Insert cutting into prepared soil and firm wit your fingers. Keep cuttings in a light shady area. With a plastic spray bottle st spray to a mist setting. Spray soil and leaves of the cutting.

    This protocol is used by commercial growers/nurseries

    • Tony Gomez says

      September 1 at 4:36 pm

      Thank you for posting this Perry! I was able to get the tuberosa to start rooting in water (like the curassavica) but did not have luck with the rest outdoors. First, my potting soil had fungus gnats, and then I switched to a soilless mix.

      I left out a couple of your steps including the scraping, using a powder root hormone, and spraying daily since we have been getting a fair amount of rain. Are you just using a regular, all-purpose potting soil?

      I am going to retry using your steps and will edit this article over the off-season. Thanks again for this helpful comment!

      How long after treating with the hormone can it be replanted in the ground?

      • Tony Gomez says

        September 5 at 10:38 am

        Hi Kristy, you place it in the growing medium right away…I successfully transplanted a couple of ours this spring after I saw new leaf growth.

    August 20 at 7:22 am

    Hi. (from San Diego) This June we were amazed that a Monarch found and laid eggs on the plant we bought within a few weeks. I had to buy more and more plants because the caterpillars ate SO much! We’ve raised over 15 butterflies and now have about 15 new eggs. I hope to sell plants from seeds as a fundraiser at my children’s school in Spring 2015. Seedlings we soaked in water for two days, then planted, are growing. 🙂

    How long do you think cuttings have to be to work? (with growth hormone and soil).

    Thanks for all the info on your website!

    • Tony Gomez says

      August 21 at 4:53 pm

      Hi Sherry,

      this is my first season rooting native cuttings so I will report more info as I get my results. The reason I am doing this is because there isn’t a lot of info available on native milkweed propagation. I’m hoping to change that so gardeners and monarch enthusiasts have more options to grow milkweed. Please keep me posted on your results too!

    I just purchased my first milk weed plant @ a nursery today but don’t know what kind it is, its about 3 ft. tall and blooming . I plan to take cuttings tomorrow and will do the potting soil & then the water also , this is my first time to plant milk weed.

    I live in Alvin Texas

    • Tony Gomez says

      August 18 at 4:05 am

      Hi Harry, what color are the flowers? Tropical milkweed is a non-native most commonly sold in nurseries. It has red and yellow blooms. It is the easiest milkweed to start from cuttings.

  15. Bryon/Jamison says

    Starting our cuttings today from Ascelpias incarnata. We’re using potting mix and rooting hormone. We’ve raised and released over 15 Monarchs here in Minneapolis. Still have 5 chrysalis and many caterpillars left to raise.

      • Helen says

        August 12 at 9:14 pm

        Tony, I took some Incarnata cuttings because I was trying to train some new seedlings into branching out. I stuck the tops into a glass of water and placed it on my kitchen counter for a month. All the leaves fell off and they all looked dead or dying. I moved them outside to my hot, steamy but shaded potting bench intending to give them one last change and stick them in soil. But of course I forgot about them for another couple weeks. And now, lo and behold…4 or 5 out of six have rooted!

        • Tony Gomez says

      Thanks Bernice. Another good source for fall planting is late summer plants sales (local and online). I love fall planting because it puts your garden way ahead of schedule for next season.

  17. Meredith says

    August 3 at 12:11 pm

    I have milkweed but not a monarch to be seen in my part of Atlanta. I definitely wish you all the best with the cuttings – but until I actually get some monarchs I will cheer you on from the sidelines. I will say I had some decent luck with winter sowing – I’ve got tuberosa blooming and healthy swamp (no blooms). Interestingly the tuberosa and swamp that I bought spring 2013 has not bloomed. The best performer here is the tropical which was direct sown and is going gangbusters. Anyway please send me some monarchs!

    • Tony Gomez says

      August 3 at 2:48 pm

      Hi Meredith, when there are no monarchs around, it’s the perfect time to work in your garden without distraction! Creating a butterfly garden is a process, and once the butterflies finally find your garden they really do keep coming back!

      I have also had problems with tuberosa flowering before I moved it this season. It’s now growing in richer soil with compost amendment. And it’s flowering too. Mature butterfly weed can be moved in spring/fall (when it’s cooler) if you dig deep and get most of the tap root. Swamp milkweed doesn’t spread through rhizomes and is easier to transplant. Transplanting is an option IF their current spot is contributing to the growing issues.

      I promise to send lots of monarchs in 5-6 weeks!

      • Cathie Nunez says

        August 10 at 9:17 am

        I dug up some wild butterfly weed 3 weeks ago, I dug deep and found that one looked healthy for over a week but the other had just “died”. a few days ago I found a healthy new start growing up between the”dead” plants stalks. I was so depressed to become so overjoyed! I live in Indiana if this helps anyone

    August 2 at 11:40 pm

    I noticed that some small tropical milkweed plants I ordered in the mail came with some stems that bent down and must have touched soil nearby, because they were putting out roots. Has anyone tried to reproduce tropical milkweed by layering?

    • Tony Gomez says

      August 3 at 12:33 am

      Hi Noreen,

      it wouldn’t surprise me if this was possible, however tropical milkweed stems typically grow upright upright so you would have to force them down to the soil. Also, you would have to separate and space the plants out at some point.

      Tropical milkweed is most easily propagated through stem cuttings in water or soil:

  20. Joy Gaiser says

    August 2 at 10:07 pm

    Yes! Keep posting. Sounds like it would be a great way to enlarge the milkweed, although I find it springs up in the most unexpected places! My rose garden is full of common milkweed and it was never there before!

    • Tony Gomez says

      August 3 at 12:21 am

      Hi Joy,

      personally I would not do this for common milkweed, since it does spread so easily on its own. However, since this is a native-only experiment, I just had to include it!
