planting milkweed for monarchs

milkweed, as nectar is critical for fueling monarchs during . Fall Planting Milkweed For Spring Monarchs. There are over 100 milkweed species, and not all are good for monarchs. Garden Betty is where I write about modern homesteading, farm-to-table cooking, and outdoor adventuring — all that encompass a life well-lived outdoors. Plant low-growing perennials in front of the milkweed, as they’ll hide the spindly “skeleton” stems once the monarchs finish feasting. their migration and overwintering. But where they go in between remains an open question. However, recently it’s been harder to find migrating butterflies. By raising them indoors, you can potentially raise their survival rate from under 5%….to over 95%! They feed on the seed pods but don’t do any damage to the plant itself (or the caterpillars). Nectar-rich flowers provide food. Sadly, the tropical milkweed species Asclepias curassavica is heavily marketed because it is easier to obtain. OE is found in all species of milkweed, but isn’t a problem with natives because the leaves are only desirable to caterpillars in the early stages of growth. This is awesome! 1. In recent decades, population surveys reveal monarchs declining because of deforestation in Mexico, loss of grasslands in the Great Plains’ Corn Belt — which the Center for Biological Diversity calls “the heart of the monarch’s range” — and loss of native milkweed plants in the U.S. Planting local milkweed species is always best. The missing information, Schultz says, is the time period when the butterflies leave their winter groves and begin to breed in February, March and April. As the study elucidated, “agricultural intensification and a corresponding rise in pesticide use has been an environmental concern” that adversely affects beneficial pollinators, like the monarch butterfly. We recommend against planting large quantities of milkweed in a small area. A report by the Monarch Joint Venture found that 49 percent of winter-breeding monarchs had OE infections, compared to only 9 percent of migratory monarchs sampled in Mexico and 15 percent of migratory monarchs sampled in the northern U.S. and Canada. Terrior Seeds is partnering with AZ Milkweed for Monarchs to grow and distribute 11 unique milkweeds. The New York Times recently reported on efforts to track the Western monarch butterfly, which spends its winter on California’s central coast before heading off to breeding sites that covers a wide swathe from the state’s central valley all the way to Idaho. Best Milkweed for Monarchs. Many of the southern species, such as tropical milkweed, will grow without cold-treatment. Submissions will be included in the Western Monarch Milkweed Mapper and earn participants an entry in a weekly raffle until the project ends on April 22, according to a statement. Without it, they cannot complete their life cycle and their populations decline.”. The reason that milkweed is so critical for monarch butterflies is because it is the only plant on which both the adults and the caterpillars feed. © Garden Betty 2010-2020. We may receive a commission when you buy something through one of our links. There just aren’t enough of us,” Washington State University biologist Cheryl Schultz, a lead researcher of the community science initiative, tells Amanda Heidt at the Monterey Herald. Greenwood Nursery sent me some of their plants last year and I’ve found them to be impressively resilient, surviving not only a major heat spell, but also oleander aphids, milkweed bugs, and many, many cycles of hungry caterpillars. http://texasbutterflyranch.com/2015/04/30/tropical-milkweed-ok-for-monarch-butterflies-just-cut-the-dang-stuff-down/. Butterflyweed does best in dry, sandy soil with little nutrition. The larvae then feed on the leaves after hatching, but cause no permanent damage to the plant. The cycle of generations and migration repeats every few weeks through the summer until the butterflies are dispersed as far as Idaho. Both Eastern and Western monarch butterflies are seeing their populations plummet precipitously, worrying scientists that the future of the species is in peril, according to multiple surveys of butterfly populations. It takes only a few caterpillars to defoliate an entire plant in a couple of weeks, but sure enough, the milkweed comes back every time. And that might lead you to wonder: why milkweed? I’m curious about the red and black insects in one of your photos. Theresa Machemer is a freelance writer based in Washington DC. Its population has declined 95 percent in the last 20 years. Best milkweeds for monarchs. Perhaps the simplest thing to do is plant milkweed, an herbaceous perennial that’s the prime larval food source for monarchs. If you’d like to start preparing for spring the easy way, plant your perennial milkweed seeds (and plants) in the fall. If Monarchs lay their eggs at the wrong time, the eggs hatch infested with a parasite. Milkweed has lost considerable ground to urbanization, shifting land management practices, climate change and even herbicide misuse, like that of Roundup. The overwintering population dropped from about 200,000 in 2017 to less than 29,000 individual butterflies in 2018. Michigan State University Extension offers the followings steps on what you can do. Fortunately, milkweed can be grown in our yards and gardens so we can help in the survival of monarch butterflies. If you want to plant new milkweed, there are several species of native milkweed in the U.S. One of the most common, Asclepias tuberosa, is also known as butterflyweed. Her work has also appeared in National Geographic and SciShow. After all, the secret to a good life is... Read more », I was concerned about the OE and tropical milkweed as well but I’ve read enough that it seems that if you cut it back that should help reduce the spores of the OE. http://texasbutterflyranch.com/2015/04/30/tropical-milkweed-ok-for-monarch-butterflies-just-cut-the-dang-stuff-down/. Showy annuals like zinnias and phlox are attractive to butterflies (as well as other pollinators like bees and hummingbirds). Then, recovery of the historic monarch numbers could be possible. By hatching and feeding on tropical milkweed, caterpillars have an increased chance of being infected with a protozoan parasite called Ophryocystis elektroscirrha (OE), which weakens them as adults. Luckily, people usually don’t have to travel go far to spot a monarch butterfly. Based on the preferences by monarchs and their poten- tial for restoration, we recommend the collecting of seeds and propagation of A. angustifolia (Arizona milkweed), A. subulata (rush milkweed), A. asperula (antelope horn/spider milkweed), and A. tuberosa (butterfly weed, the … This post is sponsored by Greenwood Nursery. It’s often seen growing in fields and along the sides of the road, which means it’s drought-tolerant and a good choice for low-maintenance perennial gardens. Such habitat losses negatively impact monarch populations as they breed, migrate and overwinter. Milkweed is slightly toxic, and the monarch caterpillars munch it and become toxic themselves, which keeps them from being eaten. Several generations of offspring spawn on milkweed during spring and summer months before migration to overwintering sites even begins. To grow and sustain each gen… Sadly, the tropical milkweed species Asclepias curassavica is heavily marketed because it is easier to obtain. However, in recent years, it has narrowed its path and does not make it as far as Washington. By the end of 2019, the count was 29,418—not worse, but not better. Enjoy your spring garden planning! With shifting land management practices, we have lost much milkweed from the landscape. I’ll be resowing seeds I stratified in the fridge here shortly. This article will explain where to get seed, how to attract monarchs, and why it will make a real difference. Thank you for supporting the small businesses that support Garden Betty. Then, gently push the soil mix back over your seeds. For monarchs, habitat entails food, water and shelter, says the National Wildlife Federation (NWF) and the World Wildlife Fund (WWF). In a regular here in SE Texas it would be nipped back by the freezes anyway, as it was this year, so that helps. The researchers do not know if butterflies are not making it to breeding sites, unable to find mates, or starving along the way. They also don’t stick around for long (short life cycle) so it’s best to just live with them. And when the weather turns cold and the days get shorter, the insects return to California’s coast. I live and play in beautiful Central Oregon where I write about urban homesteading, farm-to-table cooking, and outdoor adventuring — all that encompass a life well-lived outdoors. According to the NWF, “Monarch caterpillars feed exclusively on the leaves of milkweed, the only host plant for this iconic butterfly species. We cannot guarantee that we will be able to provide all species listed. To propagate milkweed, we mimic nature. The only thing guiding them on this migration is temperature telling them when they need to travel – like a biological trigger setting them in flight,” Wolfe explained. What they do know is that the population of Western monarchs was in the millions in the 1980s, down to 200,000 three years ago, and then down to 30,000 in 2018, according to The New York Times. This effort focuses on planting milkweed and other nectar-rich forbs and reducing pesticide use in proximity to monarch habitat. Exposure to these pesticides, insecticides and fungicides, can be from “direct contact with contaminated surfaces or spray droplets, residues remaining on the soil, and consumption via food resources such as leaves, nectar or pollen.” Just as vexing are pesticides, insecticides and fungicides “applied by aircraft.” The study emphasized the “evidence of lower abundance and/or diversity of butterflies.”, The WWF affirms that “monarchs are highly sensitive to weather and climate. EcoWatch explained, “warmer temperatures increase the cardenolides in A. curassavica [the tropical milkweed species] to the point where they poison monarch larvae, delaying larval growth and stunting adult forewings. For instance, a Purdue University Department of Entomology study, published last summer 2019 in Frontiers in Ecology and Evolution, revealed that non-target pesticides, insecticides and fungicides have wreaked havoc on monarch butterflies, even at their larval stage. The No-Waste Vegetable Cookbook is my latest book. Raise Monarchs on Milkweed Cuttings– raising monarch butterflies is an awe-inspiring experience, and a much simpler one using potted milkweed plants. Garden Betty independently selects products to feature on this site. Milkweed is the single most important source of food for the threatened monarch butterfly, and planting a patch or two in your landscape is an important contribution to the continued existence of the species. When grown in warm climates where the plants don’t die back, the year-round tropical milkweed encourages monarch butterflies to overwinter in the Southern United States rather than continue their migration to Mexico. When you think about it, it’s rather remarkable how a butterfly can spot a single milkweed from the sky. Milkweed seeds are naturally spread in the fall by wind when its large pods release seed parachutes. Monarch butterflies are usually thought of as two populations, eastern and western varieties separated by the Rocky Mountains. Now, a group of researchers wants the public’s help to solve that mystery. But this invasive species is not well-suited for monarchs, yet remains the species good-intentioned gardeners are planting rather than the native milkweed species the monarchs are better adapted to. Parasite attacks can come from tachinid flies or wasps (chalcid, trichogramma). Growing milkweed can be done from the germination of milkweed seeds, the harvesting and transplanting of milkweed rhizomes (the branching roots which spread underground), or the planting of entire milkweed plants. The two also follow different migration patterns. The striking appearance of the butterflies and caterpillars also serves as a warning to predators that they are toxic. For perennials that do double duty as food for butterflies and food for you, consider planting flowering herbs like sage and oregano. Unfortunately for the monarchs, milkweed populations have dwindled due to the use of herbicides in crop fields, where milkweed pops up abundantly between rows of corn and soybeans in the Midwest. Non-native tropical milkweed fuels monarchs on their journey through southern states, but when cooler weather hits, the plant can bring parasites and starvation. What dangers do these “wrong” species of milkweed pose for monarchs? Tropical milkweed ( Asclepias curassavica ), is pretty and easy to find, but keep it as an annual or grow it indoors. I have a few species of milkweed in my backyard, including butterflyweed. This site uses Akismet to reduce spam. Monarch Butterfly Populations Are Plummeting, Your Butterfly Photos Could Help Monarch Conservation, Steve Corey via Wikimedia Commons under CC BY-SA 2.0. By the time the temperature cooled enough to trigger the migration, it’s been too cold in the Midwest and many monarchs died on their trip south.”. (Coupon expires April 15, 2017.). Milkweed is both a food source and a host plant on which the monarch lays its eggs, depositing them on the underside of the leaves. Emory University emphasizes that climate change affects pathogen development, parasite survival rates, disease transmission processes. According to a new population survey, the Eastern monarch has passed the extinction threshold, according to a new population survey by the Center for Biological Diversity. A shallow dish with pebbles can hold water. "The challenge is keeping the food here," Day says, noting that a few monarchs can defoliate a plant in a couple of weeks. Unlike adult monarchs (butterflies), caterpillars cannot simply feed on any plant they please. Defining the “best” requires a combination of region, butterfly preference and plant performance. Thus, planting the non-native milkweed can have a negative impact on the population of monarch butterflies. Create Habitat for Monarchs. Place 1-3 Milkweed seeds in each hole. The researchers — from Washington State University, Tufts University, the nonprofit Xerces Society for Invertebrate Conservation, and the University of California, Santa Cruz — need photographic evidence, a date and a location to confirm where the monarchs might be living. By the time the butterflies reach the Central Valley, the butterflies breed. Speaking to Sarah Wright at the Half Moon Bay Review, Schultz added, “Maybe it’s early flowering native milkweeds, or maybe they’re roosting up in the woods, or maybe they need more fuel along the way… Any of those things might help monarchs get from the coastal overwintering sites to breeding sites broadly in the Central Valley.”. “These behaviors are almost exclusively restricted to sites where tropical milkweed is present.” Why Milkweed is Important Monarch butterflies rely on their host plant, milkweed, for the most critical parts of their life cycle. Equally important are perennials, especially native perennials like echinacea (coneflowers) and coreopsis, that can provide a constant and reliable source of food. That’s what I’ve learned as well. The nation’s leading Monarch conservation organizations now recommend planting only native milkweed species. The Western monarch, which is slightly smaller and darker than the Eastern monarch, has a more constrained migratory pattern. Habitat loss stems mainly from the deforestation of overwintering areas, climate change‘s fluctuating weather patterns, developmental sprawl, plus the conversion of U.S. grasslands into ranches and farmlands. In fact, recent studies show that it takes up to four generations for monarchs to make it north out of Mexico and into Southern Canada! We’ll see. By planting native milkweed, particularly the correct native milkweed species for our area, we can help maintain a safe, healthy natural food source that monarchs have relied upon for thousands of years. Yet another way climate change adversely affects monarch butterflies is by disrupting their migration. You’ll still be able to see them bloom, as the caterpillars don’t eat all the way up to the flowers. “We just don’t know what they’re doing in that middle period and how we can better support the population,” Schultz says to the Monterey Herald. “But in recent years, the monarch’s fall south migration from Canada has been delayed by as much as six weeks due to warmer-than-normal temperatures that failed to trigger the butterflies’ instincts to move south. This is because monarch caterpillars depend on the plant for food, eating every leaf in their path until they complete their metamorphosis (a cycle that takes about four weeks). If you plant it, they will come. Monarch butterfly › They depend on environmental cues (temperature in particular) to trigger reproduction, migration, and hibernation.” Their decline is also attributed to “the effects of an increasing frequency of extreme weather events such as drought and severe storms, and extremes in hot and cold temperatures.” No wonder then that the Environmental Defense Fund‘s Director of Conservation Studies, David Wolfe, has lamented that “The iconic and beloved North American monarch butterfly is one of the species that has difficulty adjusting to our new climate-stressed world. “Something’s going on in early spring,” said Cheryl Schultz, a professor at Washington State University in Vancouver, to The New York Times. Planting milkweed is a great way to help other pollinators too, as they provide valuable nectar resources to a diverse suite of bees and butterflies.
