Are You Ready To Raise Monarch Butterflies for the Monarch Migration?

Supply List For Raising Monarchs

Supply List Suggestions for Raising Monarchs to Release for the Great Fall Migration- Raise the Migration
Welcome to Raise the Migration 3, where you’ll be raising magnificent monarch butterflies to help increase the number of monarchs that will be overwintering in the mountains of Mexico and southern California.

My name is Tony Gomez, and I’ve raised thousands of monarchs over the past 30 years. My goal is to help you learn how to raise more monarchs with less effort, while helping the struggling monarch population recover.

Here are more details about Raise the Migration, including my suggested supply list for raising monarch butterflies:

Who is Raise the Migration for?

  • Those concerned with saving the monarch migration for future generations
  • Those who want to raise healthier monarch butterflies
  • Those looking for a more efficient process to raise monarchs
  • School teachers and kids looking for an exciting (and educational!) way to start the school year
  • Those interested in joining a passionate community of Monarch Enthusiasts

Feel free to share this post with others you think would be interested in participating!

How Many Monarchs Will You Raise?

This challenge was created for anyone raising between 1-20 monarchs at one time. If you want to raise more, I recommend using additional cages to avoid potential diseases caused by overcrowding.

Do You Have To Start On An Exact Date?

It’s unlikely that we would all have new monarch eggs on exactly the same date. Therefore, I will start sending tips during the earliest part of the migration, so you can refer to them when you have monarch eggs or caterpillars secured.

My tentative start date is Saturday, August 15th, 2015. This should allow most northerners to still participate and get their monarchs headed south before the weather becomes an issue. My start date might be a few days later depending on how cooperative the ELF’s (egg laying females) are. I will send out an announcement as soon as Raise The Migration begins.

When Will The Monarch Migration Be In Your Region?

Check out this monarch migration chart from Monarch Watch. I would recommend releasing your butterflies no more than 2 weeks after the last date of your peak migration. My latitude in Minneapolis is 45° N so my last peak date is September 10. This means I will try to release my last butterflies by September 24th.

You do not need to follow along in real-time to participate! Refer to the raise emails you will be receiving and start at a time that makes sense for your your region.

Does It Matter Where You Raise Them?

Keep in mind, cool nights below 55° F will slow down the metamorphic process. It’s very possible to have cooler nights in late summer (especially north) so bring your cage indoors on these nights, if your raising cage is outside. We raise ours inside a 3-season porch.

Before we get started, you will need to get set up with a few basic supplies. These supplies will help you raise monarchs for years to come, and they should fit most budgets. Some of you might not need to spend anything if you’ve already got the supplies at home.

Here are the butterfly raising tools I use to make raising migration butterflies easier, less time-consuming, and ultimately more enjoyable.

Caterpillar Cages

To raise migration butterflies “the easy way” requires a cage that can hold a potted milkweed plant or stem cuttings:

1a. Raising Cages in Many Sizes

A fantastic variety of caterpillar cages for raising monarch butterflies. The cage heights range from 1 ft. to over 4.5 ft. to accommodate potted plants. If you plan to use stem cuttings to feed caterpillars, I would suggest getting a cage at least 2 ft. high.


1c. Kritter Keepers on Amazon

These hard, plastic containers are perfect for raising caterpillars if you place pantyhose over the cage lid. This prevents small caterpillars from escaping, and you can still secure the lid. The XL cage is still a foot high and can fit small cuttings.

If you haven’t signed up to participate in Raise the Migration 3, sign up here to receive free raising tips delivered to your email inbox.

Milkweed Plants

If you want to raise monarch butterflies on milkweed with the least amount of effort, you have two options:

  • large potted milkweed plants with healthy leaves
  • milkweed stem cuttings from potted or garden plants

The best place to find milkweed plants is in your garden or from a local nursery that doesn’t spray with harmful pesticides. Remember, systemic pesticides can not be rinsed off and remain inside the milkweed leaves.

2a. Tropical Milkweed (Asclepias curassavica)- this seems to be the preferred egg laying milkweed late in the season. If you have tropical mw in your garden, transfer one to a pot now and you’ll be good to go.

2b. Swamp Milkweed (Asclepias incarnata)- first and second year plants are usually the best options since many still have fresh leaves late in the season.

2c. Goose Plant (Asclepias physocarpa)- this milkweed always has viable, healthy leaves late in the season. It’s also easy to pot if you have some in your garden.

2d. Giant Milkweed (Calotropis gigantea)- this is not widely available but could be an option in places like Florida.

2e. Popular native species like Butterfly Weed (Asclepias tuberosa) and Common Milkweed (Asclepias syriaca) are usually past their prime by late summer. However, you can use them if the leaves are still green and appear healthy.

One monarch caterpillar can devour an entire milkweed plant. Keep this in mind when deciding how many monarchs you want to raise.

If you can’t find milkweed plants locally, some of the stores on my resource page might have plants in stock:
Order Milkweed Plants Online

Monarch Eggs

During the past decade, it has become increasingly difficult to find monarch eggs. If you don’t want to wait for your milkweed to work its magic, check out these sources to buy eggs and caterpillars.

3a. Monarch Eggs from Rose Franklin

Monarch Caterpillars

If you want more of a ‘sure thing’ when ordering monarchs, caterpillars are probably your best option since a % of eggs won’t hatch.

3b. Caterpillars from Rose Franklin

3c. Caterpillars and Chrysalises from Shady Oak


Grocery List

The uses for these supplies will be explained (in detail) during Raise the Migration:

Choose one of the following 3 options:

4. Empty plastic bottle, empty jar, or vase to place stem cuttings cuttings

5. Small plastic food storage containers for shorter stem cuttings

6. Floral tubes for stem cuttings or individual leaves

Even if you are attempting to raise on potted plants, if you run out of milkweed you will have to use stem cuttings or even individual leaves

7. Pruning shears to take cuttings

8. Plastic wrap to cover empty bottle/vase

9. Rubber bands to secure plastic wrap

10. Scissors

11. Duct Tape

12. Cotton Balls

13. Aluminum Foil

Choose one of the following 3 options:

14a. Oranges or Watermelon- in case you need to keep monarchs overnight due to inclement weather

14b. Gatorade can also be used to feed adult butterflies. Melon flavored gatorade has been suggested by universities.

14c. Sugar or granulated hummingbird food can be mixed with water and fed to butterflies with soaked cotton balls.
15. Bleach for Cage Cleaning

16. Small handheld vacuum for cleaning up frass (caterpillar poop)

Some of these items are optional (depending on your raising set up) and some of these items will already be in your home. Being prepared in advance will give you more time to enjoy this amazing experience…

If you have any questions or comments about raising supplies please post below. I look forward to raising the migration with you!


  1. Sheri DeLoach says

    Interesting article & info. I would like to part update in ‘The Flight.”
    Probably need to order eggs.
    And will need a BF castle.
    Are these things you sell?
    I live in Central Texas, Waco/Hewitt.
    Very hot now & will be end of Aug
    I have Butterfly Milkweed plants I can pot up.
    Sheri DeLoach

    • says

      Hi Sheri,

      I’m happy to hear you are participating in the Amazing Raise! I don’t currently sell anything on the list, but these are products I use myself and the vendors are all reputable. In Texas, you will be at the tail end of the migration so you might want to start at the end of September or early October. I’m starting ‘early’ so everyone has a chance to participate.

      • says

        thank you for the reply,Tony. I am encouraged to go with your program as the Monarchs are beginning to migrate through our Cen-Texas area. Zone 8. I would like to buy the least expensive, most effective products for raising them inside a laundry hamper. I saw a large female Monarch depositing her eggs on the undersides of the common milkweed plant about 10 days ago. I can still see the ‘white dots eggs.’ Should I leave them on these outside plants until I can set up a laundry hamper? Also, is it too late to order eggs?
        Thank you,

        • says

          Hi Sheri,

          because there are so many egg-eating predators my suggestion is to take the eggs inside as you see them. I would check the egg suppliers on the resource list to see if they are still offering eggs. If yes, you should still be able to turn out one last Texas batch…

  2. marcy says

    I just released 4 Monarchs today. I have 2 chrysalis left to mature. Hopefully I will find more cats on my Milkweeds to raise!
    I have not been seeing as many Monarchs lately.

      • marcy says

        Tony I am in Central Florida. This is the first time I have raised Butterflies. In the past few days I have found 5 cats on plants in varying instars. I have them in containers in the house since I have had several go missing if left on the plants outside. I have a medium size foldable butterfly tent just a little too small for my potted plant. though.
        Up till today I have raised about 10 Monarchs. I am so happy to contribute a small part in raising these beautiful natural jewels. I am amazed at their beauty and grace.

        • says

          Hi Marcy, don’t worry if your potted plant won’t fit in your cage. I will also be discussing using “cuttings” instead. Happy to hear you’re having a successful season and I look forward to helping you raise more monarchs.

          • Marcy Isherwood says

            Hello Again Tony,
            Update on my last post. I now have 7 monarch chrysalis’. I have not seen a Monarch in 1 1/2 weeks. No cats on my Milkweeds.
            Are they migrating north for their migration to Mexico?- Or should I look for other reasons, such as lizards , wasps and ants and other nefarious bad guys?
            Marcy :-)


          • says

            Hi Marcy, the migration has begun in Canada. Usually, this is the time I start seeing migrators come through in Minneapolis. However, we’re having record heat all week…not sure if that might delay southward movement. I’ll be sure to post when I see them come through!

            I just read a new statistic that said only 1% of monarchs survive outdoors. That seems a bit low, but it’s probably not too far off.

  3. Monique says

    Hi there! I live in Central Florida and I have raised (from egg) over 70 Monarchs so far this year and I have 35 in chrysalis, about to emerge in the next few days. My husband converted an old ferret cage, added some screen, lattice and put a lock on it. My beauties have their own condo! :)

    • says

      excellent news Monique….many Floridians are having fantastic monarch seasons! It sounds like your monarchs are living the high-life in their beach front condo :)

  4. Cathie Nunez says

    Three days ago I had my first monarch, I live in Fort Wayne, Indiana. No eggs but am excited to finally see one this season!

  5. Donna says

    Hi Tony,
    very informative!
    In the Houston area, I’m just sarting to see daily visits from monarch and other yet to be identified butterflies. There has been plenty of egg laying by the mamas, but after a day or 2, I don’t see them anymore, and have not seen the tiny cats. I’ve inadvertently diverted the wasps by filling my hummingbird feeder, but I have quite the family of lizards. Could they be the culprit?

    Anyway, I have HUGE milkweed plants, so I’m going to do like last year with your suggestion and take cuttings.
    Wish me luck! : )

    • says

      Hi Donna,

      cuttings work well for raising and they save you a lot of time too. Yes, lizards have been reported to eat monarch caterpillars so they could be your culprits. Good luck and keep us posted!

      PS…if you haven’t signed up for Amazing Raise 1, there’s still time to sign up. I just sent out an email about taking cuttings today.

  6. says

    Greetings from Ft Wayne IN have released two adult Monarchs and have 8 more instar on the ready. I was just wondering if you had found a good site for the non aggressive Asclepias purpurascens or Asclepias viridis. Have you ever used as a source for milkweed seeds. I live in a rurual area and want to grow the less aggressive milkweeds as I want to incorporate them into gardens. I have also ordered a plant of Prairie Milkweed A. sullivanti can you think of any other less aggressive milkweed types? Thanks

    • says

      Hi Brian,

      Incarnata is non-invasive if you cut off the seed pods before the burst open. I put together a butterfly plant page with links and you should be able to find what you’re looking for there.

      I have 8 different milkweed species and I’m planting some viridis seeds this fall. You also have the option of planting ‘annual’ milkweed species for your area like curassavica or physocarpa. I use both in Minnesota and they are popular late season plants for the monarchs…especially tropical (curassavica) since it also serves as a nectar source.

  7. judith ross says

    It appears the eggs, cats that i have collected off of the outdoor plants (and then transferred to my lanai onto 2 potted tropical milkweeds) have possibly oe or something else. They are growing well, eating and then all of a sudden seem to be unable to move their rear section forward. The upper segment moves. Have you ever seen this? I have 4 cats almost ready to cocoon in this sad state. Any advice? Do i need to do something to the plants if i stat with ordered eggs? I am hesitant to use anymore “wild” eggs. Help! and thank you.

    • says

      Hi Judith, one of the reasons I’m doing “Raise the Migration” is to teach people the system I use for raising healthy butterflies. My survival rate with wild eggs is over 95% and I hope I am able to boost yours too. I will be covering the entire process when we get started in August. I’m glad you are joining us!

      As for your current caterpillars, I would see what happens. If they aren’t able to successfully pupate I would euthanize them by placing them inside a plastic bag in the freezer and then discarding. It’s hard to say what the issue is without seeing them. It could be disease. If the plants are new, could they have been treated with pesticides?

  8. Lynne Jenkins says

    I raised about 10monarch last summer and winter. This year I have none. I saw some but then they were gone. I’m thinking the wasps ate them .How do I get rid of the wasp and not hurt the caterpillars?

    • says

      Lynne, there are lots of monarch predators out there. The best ways to defeat them are 1. milkweed diversification…grow several types of milkweed and have several patches around your yard/garden 2. Raising indoors (or an outdoor enclosure)

      …and even though wasps kill caterpillars, they are also beneficial pollinators.

  9. Vicki Wallace says

    Hi Tony, I am in South Florida – am I right in my thinking that monarchs from this area don’t migrate? Since early spring we have had a steady stream of caterpillars and butterfly visitors in to our butterfly garden. At one point we had so many caterpillars I had to take 40 to my local butterfly sanctuary. Yesterday I released 5, today I released 6 and I still have 6 in chrysalis stage. I have noticed that the frogs like to eat the caterpillars so we are working on that right now!!

    • says

      Hi Vicki, central and south Florida both have overwintering monarch populations that won’t make the journey to Mexico. However, most of the information in Raise the Migration should apply to Florida monarchs too. In areas where monarchs live year round there are some disease/parasite issues (like OE) that are more prevalent because of the reuse of milkweed plants. We will discuss how to avoid (or at least reduce) these issues.

      • Vicki Wallace says

        Thanks for the info Tony – will be looking forward to learning about that. We have a few issues with our plants right now so we have just sprayed and washed them all. Taking off the eggs and cats first! I just released 5 more butterflies today :)

  10. Lynn says

    Tony – when you start posting more info, would you please explain about how to use the Gatorade / watermelon to sustain a monarch before release? Do you pour some in a dish, or ???

    Love your newsletter! Thanks for taking the time to educate the rest of us!

    • says

      Hi Lynn, I will definitely be sharing more details about feeding adult monarchs with fruit and/or gatorade. You won’t need to feed them if you release them within 24 hours, but it’s good to have some on hand just in case!

  11. Dawn Leon says

    How do I become part of this great adventure, The Amazing Raise? It sounds great!! I live in Maquoketa, Iowa and have raised and released just four monarchs thus far, but the exciting news it that they are all coming from my milkweed I planted in my own yard. I used to have to go walking in ditches, etc, to find my caterpillars, but now I just have to go to my backyard to find them. I LOVE it :) So do my kiddos.

    Thanks, Dawn

  12. jeri says

    Hi! I just took cuttings of a milkweed plant and put them in my house. I noticed, today that there are very small caterpillars on them (about 3-5).
    I am so excited. Do I now leave them in the house? And get started with the cage and equipment you suggested?
    I LOVE this site! -Jeri

    • says

      Hi Jeri, congratulations! I would definitely raise your new babies inside. I leave ours in a 3-season porch with the windows open, but you can also raise them indoors. They will typically develop a little slower indoors…especially if you have the A/C on.

      I would order a cage if you don’t have one. You can put them in a plastic food storage container until it arrives. Wherever you put them, make sure there aren’t any openings a tiny caterpillar can crawl out of…

  13. Kathy Welte says

    I raised a few monarchs 2 years ago from cats I collected on the side of the road. I planted milkweed in a new garden that is devoted to butterflies that year. Last year I did not find an egg or a cat. This year I am happy to say I am addicted. I am currently raising 22 eggs, 33 cats & 5 chrysalis. I also have 2 Monarchs which would have been released today but it has been rainy and cool. I added nectar on a sponge and a vase of zinnia & black eyed susan for them. I will probably have to go back to the roadside for milkweed to feed them all but I really don’t mind. Watching their life cycle is so enjoyable. Thank you for all the information you have on this site. I am so glad I found it.

  14. Poppy says

    Brand new to “helping save the Monarchs”.. Ordered some tropical milkweed seeds, now I have about 8 plants 25 in. tall in an area behind my regular flower garden. Have been watching all summer plants haven’t bloomed. Monarchs have been visiting my regular flower garden for several days. Today I’ve found 2 large cats on two separate milkweed plants and several very small cats. I think I’ve identified the eggs that you’ve shown how to find. I want to order a cage but most sites are sold out. I may have to try and make a homemade one in the meantime. I really enjoy your instructions and hope to get successful in raising these beautiful creatures. I’ve been stopping on roadsides and looking at the common milkweeds but haven’t seen any monarchs on them. The common plants are starting to dry up this time of year, here in St. Louis area, but I intend to keep looking. Thanks again, Tony.

    • says

      Hi Poppy, I hope you are enjoying your first season of gardening and raising. Tropical milkweed is an excellent variety for those in the central and northern US if you start with plants or cuttings. I’m in Minnesota and our tropical has been blooming for 2 months. Seeds start too slow in colder regions…especially if you have a cool spring! You might want to consider fall planting swamp milkweed too…that usually stays viable longer than common milkweed and is less invasive:

      Swamp Milkweed

      As for cages, did you check out the options on my supply list?

  15. Terrie Eshleman says

    I have one of the large pop up cages. I have used it for the last several weeks raising Black Swallowtails on fennel. My first time ever doing this.
    Now I have brought in a common milkweed with three cats and added two more on leaves today of the Monarch’s. Do I need to provide any
    sticks or other vertical support for the cats when they will be developing into chrysalises, or will they hang on the sides as the black swallowtails did?

    Also, I ordered some eggs/cats from the butterfly lady, and they have not been sent yet, August 21. Will they have enough time to develop if they are not here soon. We here in SE Pennsylvania have been having a much cooler summer than normal. Thanks for your efforts. I feel better trying to help with all your suggestions and education.

    • says

      Hi Terri, monarchs will pupate on the roof of your cage…no sticks necessary. You still have time to raise one final batch, but in your region you will want to release your monarchs by the first week of October…at the latest! It would be best if you could start raising next week. Good luck…

  16. Alice Snyder says

    I had a Monarch lay about 8 eggs on 2 potted plants outside on 8/30. I moved the plants into a screened in porch to protect from predators. I have now cut off the leaves the eggs were on and put them into a plastic pet cage, with a vented lid. 3 eggs hatched this morning. My question is should i move the cats when they are a little bigger, back onto the plants in the screened in porch and let me eat the rest of the leaves there? There are plenty leaves on the plants, or should I leave the cats in the cage and let them pupate there?

    • says

      Hi Alice, congrats on your new babies. I’m not sure what kind of cage you have, but if they can slip through the vents at the top of your cage, they will. If they are on potted plants, they might also crawl away from them before they are ready to pupate. You will want to raise them, where you can keep them the most secure. Here is a recent post about recommended cages:

      Monarch Caterpillar Cages

      • Alice Snyder says

        thanks, i ordered a pop up large container with a zip side door. I will keep them in the critter keeper until i get it and them move them to the potted plants inside this pop up container. Thanks! i now have 7 cats. I found some more today on the potted plants.!

  17. Debra Stallings says

    Hi, Tony,
    I wrote you once before. I am a Master Gardener in Montgomery County, TX (about 45 miles north of Houston). I believe we are now zone 8b. We grow A. curassavica like weeds! But we want to offer natives as alternatives, especially in our plant sales to butterfly enthusiasts. We started A. tuberosa with some success (some look great and some, not so much). We also have a healthy crop of A. physocarpa that look very good along with our A. curassavica. Our next sale is September 19, 2015.
    My question is, when do we start the seed of A. asperula and A. viridis. We mail ordered the seed which suggested we start the seed in the “fall”. So when is THAT?? Our next sale is March of next year, and we would love to offer them then. Is that possible?. When should we start them? Is it too early now (or too late?) We have a greenhouse if they need to stay indoors for the winter. Any help would be greatly appreciated. I’m trying get all of us who have the Mexican/tropical milkweed to cut it back about mid to late October, because of the Oe parasite, right?

    Thanks for your help and your wonderful passion!!

    • says

      Hi Debra, the info you’re getting about planting in fall is probably meant for gardeners who want their seeds to sprout outside in spring. When you plant for your greenhouse should depend on the size of plant you want to offer at your spring sale. I would suggest doing a test to see how long it takes viridis/asperula seeds to germinate after cold moist stratification…then see how long it takes the seedlings to get to the size that you want for your plant sale.

      Any milkweed in your region that grows continuously should be cut back, so that would probably include physocarpa too. Hope this helps, Tony

  18. says

    I live in southern ca to be exact the San Fernando valley. It gets quite hot here in the summer and sometimes very cold in the winter. I have a 13ft x
    4ft veg garden I want to turn into a butterfly garden. Will you give me a list of plants I can use
    Thank you for your time.

  19. JUDY KARCHER says

    Tony ,
    I released four Monarchs this morning ,3 Male and Female ( second generation ) .

    Hope they me some third generations .
    Cages are all cleaned and just waiting for the eggs to be laded.


  20. Judy Schafer says

    It’s 100 degrees here in Texas. However a friend in Navasota has Monarch in her yard. Today was the annual butterfly release ( painted ladies) for our jr. science museum. There were 500 plus attended. Our garden club for the 3rd year did an educational booth and showed pictures of local butterflies in the TV viewing room. We gave out seed, mixed nectar and host, plus pks. of tropical butterfly milkweed seed. We also provided lists of suggested butterfly plants for our area. We have been invited back for next year.
    President Obama has announced Interstate 35 from Mexico to Minn. as ‘pollinator corridor’ The U.S. Department of Transportation and U.S. Fish and Wildlife Service will help rehabilitate butterfly habitat along the federal highway.

    • says

      I have heard more reports of people seeing monarchs down south. I think the abundant milkweed supply (from all the rain) enticed more to stay! It sounds like your booth was a huge hit…congrats Judy!

  21. Patricia says

    I haven’t seen a single Monarch all year. I had 20 cats on my milkweed in 2011 and haven’t seen any since, just migrating monarchs nectaring. Butterflies in general have been very sparse here all year. I have all kinds of nectar and host plants and have only seen 3 butterflies. Very strange.

    • says

      Sorry to hear this Patricia…and another reason it’s important to raise migration generation monarchs if you are able. I hope you start seeing more butterflies soon!

  22. Poppy says

    This is my second year “Monarching”. I live about 20 West of St. Louis, Mo. Last year being new at it, I didn’t get any releases until late August, and had limited milkweed. This year I have about 35 milkweed plants, mostly tropical. I started observing eggs about the first week of July. As of today I have released 13 about 8 males, 5 females. Last year I had one cage, bought 2 more for this year, and put them on my screened in porch. Most of my milkweed are in pots, so I can bring them into the cages, out of harms way. Since several plants get eggs, I pick one and place it in a cage. I observe the other plants and wait until I see the new hatching muching away. I carefully force them onto my finger and bring them into the cage and transfer them to the waiting milkweed. Egg laying took place for about a week, and I haven’t observed any more eggs, here it is July 25th.
    I have about 17 more chrysalis’ in various stages waiting for the new Monarchs to emerge. So far, they have all emerged healthy and ready to head out. I think getting the newly hatched cats inside is the secret, getting them away from the outside predators. I do see Monarchs fluttering around my flowering plants, especially the Mexican sunflowers, but no egg laying as of yet. Since I didn’t have eggs this early last year, I wondering if this lapsed time is normal, I guess time will tell.

    • says

      Hi Poppy, once your garden is more established, you will probably get more eggs over the summer, but the monarchs can be unpredictable…a late start to the season doesn’t help either! Congrats on your early batch, and hope you get more soon…

  23. Sharon says

    I live in North East Texas and raise Monarchs with my Kindergarten class in the spring (for over 20 years now). I find the eggs on milkweed plants on my land. I learn more and more each year. My question is do the Monarchs lay eggs here in Texas in the fall on their flight back to Mexico for the winter or do they just pass through on their journey to Mexico for the winter?

    • says

      Hi Sharon, the monarchs that have entered sexual diapause will move through to Mexico, but there will definitely be some that are still mating and will leave eggs in your region. A September/October raising project for your class would probably work well…good luck!

  24. Shari says

    This my first year and I am so amazed, what an incredible miracle. I have released 11 butterflies so far, have two chrysalis, and one big one ready to “J” out. I am sorry to say I have lost three caterpillars and two chrysalis to that parasitic fly, that was terrible.

    I am curious how you know male from female butterflies? I seem to always call them, she.

    Thanks for all your info.

    PS I am in SoCal, is there a time I should cut all of the milkweed back?

    • says

      Hi Shari, I’m glad you are enjoying your first season raising monarchs! Here is a post that illustrates the differences between the sexes:

      Monarch Female VS Monarch Male Photos

      As for cutting back, I would do it once at the end of the season and then another time during the season when activity is low. You can always stagger the cuttings so there will be some milkweed available if a monarch female stops in for a visit. Hope this helps!

  25. says

    Greetings from Santa Cruz, one of those spots where Monarchs migrate to in the winter. I have released seven this spring, right now I have 12 in chrysalis that should emerge in a couple weeks. I have about seven small caterpillars and five more eggs. So some of the Monarchs stay around here all year. Hopefully in Oct. we will get more butterflies this year, last year the numbers were quite small.

    I find most of the eggs on the tropical milkweed flowers and the swamp milkweed leaves. I am trying to grow heart shaped milkweed, as it is a California native, but it is not really growing very well, only one seed sprouted and the plant has remained very small. I looked at your pdf for California native milkweeds, and the growing area for Heart shaped milkweed is more north and inland from where I live. So tropical is the best for us by the ocean. This year the local nursery has three colors of tropical milkweeds, yellow, red and orange. Last time I was there, a week ago, people were flocking to buy the milkweeds. More and more folks here are interested in butterfly gardens and specifically Monarchs. I have many nectar flowers now and I see not only Monarchs, but Gulf Fritillaries, Painted Ladies, Swallowtails, Skippers and of course Cabbage whites. It is such a wonder to see them all flying around, doing their mating dances, sipping on the zinnias.

    I think that growing a butterfly garden is healing on so many levels, it certainly reduces my stress and I feel like a child again, free and in wonder with the world when the butterflies come to visit. And baby Monarchs are so incredibly cute!!!

      Hi Gabrielle, I know exactly how you feel when the butterflies flutter in for a visit. Sorry you are having problems with your California natives, but from what I hear, you aren’t the only one! Besides tropical, you might also want to look at the Calotropis and Gomphocarpus milkweed varieties, that would probably be perennials in your region. They aren’t native, but grow well in warm climates:

    First…thank you for all of the info. I just wound up my second season. I’m very pleased how everything worked out. I would guess that I released nearly 100 beautiful Monarchs.
    I have had no luck with growing new plants from seed so I have started rooting cuttings. I have lots of cuttings with roots. I would like to know when do I plant these in soil? Also, how far back do you cut the existing plants. I have 30 plants that are quite big. I think they need to be cut back. I just don’t know how far and when is the best time.
    I live in Orlando. It seems that we have Monarchs year around. I have just found the first caterpillers of season three. I raise mine outdoors in an enclosure. They do quit well.

      Hi Skip, I would try cutting back to about a foot with no foliage on the plant…so it’s unusable to them until so new growth occurs. I raise indoors too skip…it’s much easier to raise healthy monarchs that way. Congrats on a successful season!
