Episode 45 – Milkweed – Wild, Vital, and Transformative · The Beanstalk : A Podcast for Gardeners

• 0:28
  Welcome back to the Beanstalk, fellow beans.
• 0:32
  My name is John, your neighborhood garden buddy, and
• 0:37
  today we're talking about a plant that might just be one of
• 0:41
  the most important things you could ever grow in your yard.
• 0:47
  Milkweed. This is not your typical tidy,
• 0:51
  ornamental showpiece. It's bold, it's ecological, it's
• 0:57
  a little wild around the edges, and it plays a starring role in
• 1:02
  one of the most incredible natural transformations on the
• 1:06
  planet. If you ever wanted your garden
• 1:11
  to do more than just look good, if you want it to matter, this
• 1:16
  episode is for you. Why grow milkweed?
• 1:24
  The short answer is monarch butterflies.
• 1:28
  Monarch caterpillars can only eat plants in the milkweed
• 1:32
  family. Without milkweed, there are no
• 1:37
  monarchs. It's that simple.
• 1:41
  When you plant milkweed, you are directly supporting their entire
• 1:45
  life cycle, from egg to Caterpillar to chrysalis to
• 1:51
  butterfly. But beyond monarchs, milkweed
• 1:56
  flowers are rich in nectar and attract a huge diversity of
• 2:00
  pollinators. Native bees, honey bees, Wasps,
• 2:06
  beetles, even hummingbirds in some areas.
• 2:11
  It's a pollinator magnet, and depending on the species you
• 2:16
  choose, you can get clusters of pink, orange, white or purple
• 2:21
  blooms that stand tall and make a statement.
• 2:27
  This is a plant that turns your yard into habitat.
• 2:33
  How to grow milkweed depends on the species, and that's an
• 2:38
  important distinction. There are over 100 species
• 2:43
  native to North America, and choosing a native variety for
• 2:48
  your region is key. Common milkweed grows tall,
• 2:54
  sometimes up to five feet, and spreads through underground
• 2:59
  rhizomes, forming colonies over time.
• 3:05
  Swamp milkweeds prefer moist soil and stay more clump
• 3:10
  forming, making it easier to manage in smaller gardens.
• 3:16
  Butterflyweed, which has those fiery orange blooms, prefers
• 3:21
  drier, well drained soil and stays more compact.
• 3:29
  Most milkweed species prefer full sun at least six hours a
• 3:34
  day. Seeds often require cold
• 3:38
  stratification, meaning they need a period of cold, moist
• 3:44
  conditions before they'll germinate.
• 3:48
  You can mimic this by refrigerating seeds in damp sand
• 3:52
  for about 30 days before planting.
• 3:56
  Once established, milkweed is remarkably tough.
• 4:01
  It develops a deep taproot, especially butterfly weed, which
• 4:06
  makes it drought tolerant but also means it doesn't love being
• 4:11
  transplanted. It's a planet where you want it
• 4:14
  to stay. Harvesting milkweed is a nuanced
• 4:20
  conversation. Generally, we don't grow
• 4:25
  milkweed as a food crop, though historically some indigenous
• 4:30
  communities carefully prepared certain parts of specific
• 4:34
  species for consumption. For most home gardeners,
• 4:41
  harvesting means collecting seed pods for propagation.
• 4:48
  Wait until the pods mature and begin to split naturally.
• 4:53
  Inside, you'll find rows of brown seeds attached to silky
• 4:57
  floss. Harvest before the wind carries
• 5:02
  them off into the neighborhood. If you're collecting for Monarch
• 5:08
  habitat expansion, you can gently separate the seeds from
• 5:12
  the fluff and store them in a paper envelope in a cool, dry
• 5:18
  place until planting season. Now let's get into common pests
• 5:24
  and problems, because milkweed definitely has a few characters
• 5:29
  that show up. First, there are aphids,
• 5:34
  especially the bright yellow oleander aphids.
• 5:39
  These are small SAP sucking insects that cluster on stems
• 5:43
  and buds. They weaken the plant by
• 5:47
  draining nutrients and can cause distorted growth or reduce
• 5:51
  flowery. They thrive in warm weather and
• 5:55
  reproduce rapidly. While they look alarming,
• 6:01
  milkweed can usually tolerate some infestation.
• 6:06
  You can spray them off with water, prune heavily infested
• 6:10
  stems, or introduce beneficial insects like ladybugs.
• 6:17
  Avoid broad spectrum insecticides because they can
• 6:20
  harm monarch caterpillars and other beneficials.
• 6:29
  Milkweed bugs are another frequent visitor.
• 6:33
  These orange and black insects feed primarily on the seeds
• 6:37
  within the pods. They don't usually harm the
• 6:41
  plants overall health, but they can reduce viable seed
• 6:45
  production. If seed saving is your goal,
• 6:50
  harvesting pods early and allowing them to dry indoors can
• 6:54
  help prevent damage. Otherwise they're generally part
• 6:59
  of the ecosystem and not something to panic over.
• 7:05
  A more serious issue can be fungal diseases like leaf spot
• 7:09
  or powdery mildew. These appear as discolored
• 7:14
  patches or white powdery coatings on the leaves,
• 7:18
  typically in humid conditions with poor air circulation.
• 7:24
  While they rarely kill the plant, they can reduce vigor.
• 7:30
  Spacing plants properly, ensuring good airflow, and
• 7:34
  watering at the base rather than overhead can reduce fungal
• 7:38
  pressure. Removing and disposing of
• 7:42
  infected foliage at the end of the season helps break the
• 7:46
  disease cycle. There's also the monarch
• 7:52
  parasite OE, short for Ophirocystis electrocera.
• 8:00
  This isn't a pest of the plant, but a protozoan parasite that
• 8:04
  infects monarchs. It can build up when milkweed
• 8:09
  isn't cut back in warm climates where it doesn't die back
• 8:12
  naturally. In those areas, cutting milkweed
• 8:17
  down to a few inches once or twice a year can reduce parasite
• 8:21
  loads and encourage fresh growth.
• 8:27
  Companion planting with milkweed is less about pairing with
• 8:30
  vegetables and more about designing A pollinator friendly
• 8:34
  ecosystem. It works beautifully alongside
• 8:38
  cone flowers, Black Eyed susans, Yarrow and native grasses.
• 8:47
  These combinations create layers of habitat and continuous blooms
• 8:51
  throughout the season. Just be mindful of spacing.
• 8:58
  Common milkweed can spread aggressively, so give it room or
• 9:02
  plant it where spreading is welcome.
• 9:08
  Seed saving is one of the most satisfying parts of growing
• 9:11
  milkweed. As the pods mature and dry,
• 9:16
  you'll notice them swelling and eventually splitting along the
• 9:19
  seam. That's your cue.
• 9:24
  Gently harvest the pods before they fully burst open.
• 9:29
  Separate the seeds from the silky floss by hand or by
• 9:32
  placing them in a paper bag and shaking.
• 9:35
  Gently store seeds in a labeled envelope.
• 9:40
  And remember that most species benefit from cold stratification
• 9:44
  before planting. It's a simple way to multiply
• 9:48
  habitat year after year. Looking at pros and cons, the
• 9:57
  pros are powerful. Milkweed directly supports
• 10:02
  monarch butterflies, feeds a wide range of pollinators, and
• 10:07
  adds bold structure and color to the garden.
• 10:13
  Many species are drought tolerant and low maintenance.
• 10:16
  Once established. The cons.
• 10:20
  Some species spread aggressively and may not be suitable for
• 10:24
  small manicured beds. The Milky SAP can be irritating
• 10:29
  to skin for some people, so gloves are a good idea when
• 10:33
  pruning. And if you're in an HOA driven
• 10:38
  neighborhood, its wild look might raise a few eyebrows.
• 10:43
  But sometimes wild is exactly what we need.
• 10:49
  And now for the best part, the recipe.
• 10:55
  Since milkweed itself isn't commonly used in modern
• 10:59
  kitchens, we are going to celebrate the monarch connection
• 11:04
  with a Monarch Garden Citrus salad.
• 11:09
  You'll need 4 cups of mixed salad greens, 1 cup of thinly
• 11:16
  sliced fennel, one large orange segmented, 1 grapefruit
• 11:26
  segmented, 1/4 cup of toasted sliced almonds, 1/4 cup of
• 11:36
  crumbled goat cheese, and two tablespoons of fresh chopped
• 11:42
  mint. For the dressing, whisk together
• 11:47
  3 tablespoons of olive oil, one tablespoon of honey, one
• 11:54
  tablespoon of fresh lemon juice, one teaspoon of Dijon mustard,
• 12:02
  and a pinch of salt and black pepper.
• 12:07
  Toss the greens, fennel, citrus, almonds, goat cheese, and mint
• 12:15
  in a large bowl. Drizzle with the dressing and
• 12:20
  gently toss until coated. It's bright, fresh and vibrant,
• 12:27
  just like a garden full of butterflies.
• 12:32
  Here are some fun facts about milkweed. 1st, the Milky SAP
• 12:40
  it's named for contains cardiac glycosides, which make the plant
• 12:45
  toxic to many animals. Monarch caterpillars absorb
• 12:51
  these compounds, making the butterflies toxic to predators.
• 12:57
  2nd, the silky floss attached to milkweed seeds was used during
• 13:02
  World War 2 as a life jacket filler because it's buoyant and
• 13:07
  water resistant. 3rd. Milkweed flowers have a complex
• 13:14
  structure with specialized parts called woods and horns that make
• 13:20
  them uniquely adapted for pollination 4th.
• 13:26
  Some species can live for decades once established thanks
• 13:30
  to their deep root systems 5th. The flowers produce an
• 13:38
  incredible amount of nectar, making them a powerhouse for
• 13:42
  honey production in some regions and 6th.
• 13:49
  Milkweed has been used historically in traditional
• 13:52
  medicine, though modern use should be approached cautiously
• 13:56
  due to its toxicity. Welcome to the garden nerd
• 14:02
  corner, fellow beans. Milkweed belongs to the genus
• 14:08
  Asclepius, named after Asclepius, the Greek God of
• 14:12
  medicine. The intricate flower structure
• 14:16
  is designed for a very specific pollination mechanism involving
• 14:21
  structures called palenia, which attach to visiting insects legs.
• 14:28
  This highly specialized system increases pollination
• 14:32
  efficiency, but also means not every insect is up to the task.
• 14:40
  The Co evolution between monarch butterflies and milkweed is a
• 14:44
  fascinating example of ecological interdependence.
• 14:49
  The monarchs tolerance of milkweed toxins is a rare
• 14:52
  adaptation and their migration patterns are tightly linked to
• 14:57
  milkweed availability across North America.
• 15:01
  It's a reminder that plants and insects are in constant
• 15:04
  conversation, whether we notice it or not.
• 15:09
  Next time on the Beanstalk, we're heading into the world of
• 15:14
  globe mallow. This tough, drought loving
• 15:18
  native brings vibrant color to dry landscapes and thrives where
• 15:23
  other plants struggle. We'll explore how to grow it,
• 15:29
  why it's such a powerhouse in arid gardens and how it fits
• 15:34
  into a water wise planting plant.
• 15:38
  If you're looking to build resilience into your landscape,
• 15:41
  that's going to be 1 you won't want to miss.
