Question 2

Planting and Growing Asclepias:

Accepted Answer

Light: Asclepias requires full sun. Plant in a location that receives at least 6-8 hours of direct sunlight daily for optimal blooming and growth.
Soil: Prefers well-drained soil. While adaptable, Asclepias thrives in average to even poor, well-drained soil. Amend heavy clay soils with compost, perlite, or other drainage materials to improve drainage. Avoid overly rich soils, which can lead to leggy growth.
Planting Time: Spring or fall are the ideal times to plant Asclepias. Avoid planting during the heat of summer or when the ground is frozen.

Planting Instructions - General (Container Plants or Established Plants):

Choose Your Location: Select a sunny spot in your garden with well-drained soil.
Prepare the Planting Hole: Dig a hole that is twice as wide as the root ball and just as deep.
Amend the Soil (If Needed): If your soil is heavy clay, mix in drainage material like perlite, sand or compost. You generally do not need to add fertilizer to the planting hole.
Remove from Container: Gently remove the Asclepias from its container, loosening any circling roots if present.
Planting Depth: Place the root ball in the center of the hole, ensuring the top of the root ball is level with the surrounding soil.
Backfill and Firm: Backfill the hole with the prepared soil, gently firming around the base of the plant.
Water Thoroughly: Water deeply after planting to settle the soil and provide initial moisture.
Mulch (Optional but Recommended): Apply a light layer of mulch (such as bark chips, gravel, or shredded leaves) around the base of the plant, keeping it away from the stem. Mulch helps retain moisture, suppress weeds, and regulate soil temperature. Gravel mulch is particularly good for Asclepias as it improves drainage around the crown.

Planting Instructions - Bare Root Asclepias:

Hydrate Bare Roots: Upon arrival, if you are not planting immediately, keep bare roots cool and moist, wrapped in damp newspaper or peat moss. Before planting, soak the bare roots in a bucket of lukewarm water for 4-6 hours (or even overnight) to fully rehydrate them. This is crucial for bare root Asclepias success.
Choose Your Location & Prepare Soil: As above for general planting.
Dig the Planting Hole: Dig a hole wider and deeper than you would for a container plant to easily accommodate the spread bare roots. Create a small mound of soil in the center of the hole.
Position Bare Roots: Place the bare root plant on top of the soil mound, spreading the roots out and down around the mound. Ensure the crown (where the roots meet the stem) is at or slightly above soil level. It is crucial not to bury the crown too deeply, as this can lead to rot.
Backfill and Firm: Carefully backfill the hole with soil, working it around the roots. Gently firm the soil around the plant, ensuring good root contact.
Water Thoroughly: Water deeply after planting to settle the soil and provide essential moisture.
Mulch (Recommended for Bare Root): Apply a light layer of mulch as mentioned above, especially important for bare root plants in their first year to help retain moisture and protect roots while they establish.

Ongoing Care:

Watering:

Establishment (First Year): Water regularly and deeply during the first growing season, especially during dry spells, to help bare root plants establish and container plants settle in. Keep the soil consistently moist but not waterlogged.
Established Plants: Once established, Asclepias is drought-tolerant. Water sparingly, only during prolonged dry periods. Overwatering is a more common problem than underwatering with Asclepias and can lead to root rot. Allow the soil to dry out significantly between waterings.

Fertilizing: Asclepias generally does not need fertilizer. In fact, too much fertilizer can result in weak, leggy growth and fewer flowers. Lean soil is preferred. If you feel you must fertilize, use a very diluted, balanced fertilizer sparingly in early spring only.
Pruning:

Deadheading (Optional): Deadheading spent flowers can encourage a slightly longer bloom season, but it is not necessary. Many gardeners leave seed pods for winter interest or for natural reseeding (if desired and appropriate for the variety).
Fall Cleanup: In late fall or early spring, you can cut back the stems to the ground for tidiness.
Dividing (Optional): Mature Asclepias plants can be divided in spring or fall if desired to propagate new plants or control size, though they prefer not to be disturbed once established.

Overwintering: Asclepias is generally a hardy perennial. Check the specific hardiness zone for your variety. They are generally quite cold hardy and do not require winter protection in most regions within their hardiness range. Mulch can be helpful for newly planted bare roots in their first winter, especially in colder zones.
Pests and Diseases: Asclepias is generally resistant to pests and diseases. Aphids can sometimes be present but are usually tolerated as they are not severely damaging and can attract beneficial insects. Monitor for root rot in overly wet conditions; ensure well-drained soil and avoid overwatering.

Enjoying Your Asclepias:

Seasonal Interest: Asclepias provides beautiful blooms in summer and fall, attracting pollinators. Seed pods can add textural interest later in the season and into winter.
Cut Flowers: Some Asclepias varieties, like incarnata, make excellent cut flowers.
Wildlife Value: Enjoy knowing you are providing crucial habitat and food for Monarch butterflies and other beneficial pollinators!

Pro-Tip: Do not be alarmed if your Asclepias is slow to emerge in spring, especially bare root plants in their first year. They are often late to break dormancy. Patience is key! Also, remember to leave some seed pods if you want natural reseeding or winter interest.

By following these guidelines, you can successfully plant and enjoy the beauty of Asclepias and contribute to Monarch butterfly conservation in your garden, whether you choose container plants or bare root options!

Question 3

What Is Asclepias?

Accepted Answer

Asclepias, commonly known as milkweed, is a genus of herbaceous, perennial, flowering plants in the dogbane family Apocynaceae. It consists of about 220 species that are native to North and South America, with a few species in Africa and Asia.

Milkweeds are known for their toxic milky latex, which contains cardiac glycosides called cardenolides. This latex makes them poisonous to most animals, but some insects, including monarch butterflies, have evolved to resist their toxicity and even use them as a food source.

Milkweeds are also important for their role in pollination. Their flowers have complex structures that attract bees, butterflies, and other pollinators. Once a pollinator lands on a flower, it gets dusted with pollen, which it can then carry to another flower and help to fertilize it.

Some of the most common milkweed species include:

Common milkweed (Asclepias syriaca): This is the most widespread milkweed species in North America. It grows in fields, roadsides, and other disturbed habitats.
Butterfly milkweed (Asclepias tuberosa): This species is known for its bright orange flowers, which are a favorite of monarch butterflies. It grows in prairies, meadows, and other dry, open habitats.
Swamp milkweed (Asclepias incarnata): This species grows in wet meadows and swamps. It has pink or purple flowers.
Milkweeds have a number of uses. The fibers from their stems can be used to make textiles, and their seeds can be used to make oil. Some milkweed species have also been used in traditional medicine.

In recent years, there has been a growing interest in growing milkweeds in gardens and other landscapes. This is because milkweeds are a valuable food source for monarch butterflies, which have been declining in population in recent years.

Here are some additional facts about milkweeds:

The only host plant for monarch butterfly larvae.
Can grow up to six feet tall.
Blooms from early summer to late fall.
Milkweeds are relatively easy to grow in a variety of soil conditions.

Question 4

What cautions should be taken with milkweed?

Accepted Answer

Milkweed is a fantastic plant for supporting pollinators, but it is important to be aware of some cautions:

Toxicity:

Cardiac glycosides: All parts of milkweed contain cardiac glycosides, which are toxic to humans, livestock, and many other animals. These compounds can cause nausea, vomiting, diarrhea, weakness, and even heart problems if ingested in large quantities.
Skin and eye irritation: The milky sap can irritate skin and eyes. Wear gloves when handling milkweed and wash your hands thoroughly afterwards. If sap gets in your eyes, flush them with water immediately.

Handling and Planting:

Wear gloves: Always wear gloves when handling milkweed, especially when cutting or pruning, to avoid skin contact with the sap.
Proper disposal: Do not dispose of milkweed clippings where animals might eat them. Compost them or dispose of them in the trash.
Avoid planting near livestock: Keep milkweed away from areas where livestock graze, as they can be poisoned by eating it.

Invasive Potential:

Some species spread aggressively: Common milkweed (Asclepias syriaca) is known for its ability to spread rapidly through rhizomes. Be mindful of where you plant it and monitor its growth to prevent it from taking over your garden or displacing other plants.
Choose native species: Opt for milkweed species native to your region, as they are less likely to become invasive and are better adapted to local ecosystems.

Other Considerations:

Pesticide use: Avoid using pesticides on or around milkweed, as they can harm monarchs and other beneficial insects.
Tropical milkweed: tropical milkweed (Asclepias curassavica) requires special consideration due to its potential to disrupt monarch migration and increase disease risk. Cut it back in the fall to encourage monarchs to migrate and reduce the buildup of parasites.

By taking these cautions, you can safely enjoy the benefits of milkweed in your garden while minimizing any potential risks. If you have any concerns about milkweed toxicity or its impact on your landscape, consult with your local extension office or a native plant expert.

However, some Asclepias species are non-native to certain regions, and these can be invasive. The most notorious example is Tropical Milkweed (Asclepias curassavica). It can spread aggressively in warmer climates, displacing native plants and potentially harming monarch butterflies by hosting a parasite that is harmful to their larvae.

General Guidelines:

To avoid problems, always choose Asclepias species that are native to your region. You can find resources like the National Wildlife Federation's Plant Finder to help you choose which species are safe to plant in your area.

Additional Factors:

Even with native Asclepias, be mindful of your planting location. Do not plant them in natural areas where they could potentially outcompete other native plants.
Monitor your Asclepias plants and address any signs of excessive spread through dividing or transplanting if necessary.

Conclusion:

Asclepias can be a beautiful and beneficial addition to your garden, but it is important to be aware of potential risks associated with non-native species. By choosing native varieties and practicing responsible planting, you can help ensure that these important plants flourish without causing harm to the environment.

Question 16

When Is The Best Time To Divide Asclepias Plants?

Accepted Answer

Whether dividing Asclepias, or milkweed, is a good idea and the optimal time to do it depends on several factors, including the specific species and your local climate. Here is a breakdown:

Dividing Asclepias - Pros and Cons:

Pros:

Propagate your existing plants to create more milkweed for your garden or share with others.
Manage overly large clumps that have become crowded or struggle to bloom.

Cons:

Asclepias generally have deep taproots, making digging and dividing them risky. Damage to the roots can weaken the plant or even kill it.
Dividing may stress the plant and delay flowering for a season.
Some species, like Butterflyweed (Asclepias tuberosa), are best propagated through seeds due to their deep taproots.

Timing Your Division:

Spring: Generally, early spring, before active growth starts, is the safest time to divide most Asclepias. The cooler temperatures and new growth can help the plants recover.
Fall: In milder climates, you can also divide Asclepias in late fall, after the first frost but before the ground freezes. This avoids disrupting their active growing season.

Species Considerations:

Some Asclepias, like Swamp Milkweed (Asclepias incarnata), can tolerate division better than others. Research the specific needs of your Asclepias variety before attempting it.
Consider alternative propagation methods like cuttings or seed sowing for species with sensitive taproots.

Before You Divide:

Choose healthy, mature plants that have established themselves well.
Water the plant thoroughly the day before dividing to loosen the soil and reduce transplant shock.
Prepare your planting holes in suitable locations with well-draining soil.

Dividing Process:

Carefully dig around the plant, trying to expose as much of the root ball as possible without damaging the taproot.
Use a sharp tool to gently divide the root ball into sections, aiming for 2-3 shoots per division.
Plant the divided sections in their prepared holes at the same depth as before.
Water deeply and keep the soil moist but not soggy until the plants are established.

Remember:

Dividing Asclepias can be risky, so proceed with caution. Consider the potential benefits and risks before attempting it.
Choose the right timing and method for your specific species and climate.
Take care to minimize root damage and provide proper aftercare for successful recovery.
