Where is the best place to plant swamp milkweed?
As its name suggests, Swamp Milkweed thrives in moist to wet soil conditions. However, it can also tolerate well-drained soils. Ensure your garden soil is rich in organic matter and has good drainage to prevent waterlogging, especially if you don’t have naturally moist conditions. In contrast, milkweed, a perennial plant with a lifespan of 8 to 10 years, is native to much of North America. When growing a crop like milkweed, soils are covered for a long period of time. As a result, soils under milkweed production are disturbed far less compared to soils growing annual crops.Common Milkweed (Asclepias syriaca) It thrives in full sun to partial shade in average to well-drained soils, and is commonly found in pastures, field edges and along roadsides. Spreading by underground rhizomes, makes this plant a good choice for erosion control. Its height can range anywhere from four to six feet.Myth #4: Because milkweed is toxic, you shouldn’t plant it Milkweed does contain toxins that can be harmful to pets, livestock and people. The milky sap for which it gets its name leaks out from the stem or leaves.Milkweeds can be propagated from seeds, cuttings, and, in some cases, from root divisions.
What to plant next to Swamp Milkweed?
Joe-Pye Weed is an excellent companion for Swamp Milkweed, thriving in the same wetland conditions. It prefers full sun to partial shade, making it easy to integrate into your garden. This plant is a magnet for pollinators, providing nectar for butterflies and bees. The quintessential period for relocating swamp milkweed is during the cusp of warm weather, as late spring melts into early summer. This timing ensures that the mild temperatures and consistent moisture levels create an ideal environment for swamp milkweed to establish its roots without the stress of extreme heat.Swamp Milkweed (Asclepias incarnata L. As a tall herbaceous moisture-loving perennial, Swamp milkweed seeks sunny openings of swamps, marshes, bogs, fens, and open areas along stream banks and ditches.Watering will be twice weekly for the first few weeks after new milkweed is planted in the fall. As the plants become established during the winter months, the watering frequency will decrease. During the summer months, watering increases in frequency depending on temperatures and precipitation.Common Milkweed is a perennial plant with a unique floral fragrance that blooms June to August. This plant is also an important larval host to the Monarch Butterflies. Unlike Swamp Milkweed, this plant prefers sunny, open, dry areas and can often be found in ditches, meadows and roadsides.Tropical milkweed, unlike our native milkweeds that die back in late fall, will continue to grow through the winter unless killed by a hard freeze. Even if the cold kills the stems, it may regrow quickly from the roots.
What not to plant next to milkweed?
Plants that require shade or even partial sun and plants that need damp soil or frequent watering will not do well in the same area as milkweed. Plants like hosta, coral bells, and Joe Pye weed will do best in another area of a yard or outdoor space. Best growing practices suggest milkweeds be planted in the sunniest parts of your yard or garden. If you have a choice of soil, most milkweed species thrive in light, well-drained soils with seeds planted a quarter-inch deep.Adding milkweed to your garden isn’t just an investment in beauty—it’s a way to support monarch butterflies and other pollinators. By planting at least five milkweed plants, you can create a welcoming habitat for monarchs while enjoying the vibrant colors and long-lasting blooms these plants offer.Cold stratification is recommended for most milkweed species (except the non-native tropical ones such as Asclepias curassavica) and will significantly help increase the germination rate. Cold stratification (vernalization) does require several weeks of preparation before sowing the seed, so timing is very important.The answer is, it depends. Annual vs. Asclepias Physocarpa pictured above, you can scatter the open seed pods around the soil and cut the stalks down to the ground.Sowing Milkweed Seeds is Easy! Seeding can occur between October and June, but should not be completed during the summer months. Once the seed is broadcast, work the seed into the soil to a depth of 1/8th inch. This can be accomplished by flipping over a garden rake and lightly moving the seed and the soil/mulch.
How aggressive is swamp milkweed?
Though not aggressive, swamp milkweed competes well and adds a nice splash of color to midsummer landscapes. It makes a great garden plant in sufficiently moist sites, preferring full sun to part shade. It will tolerate mesic upland locations — even clay soils that are watered regularly when conditions are dry. Consider using a deep pot if starting indoors, since most milkweeds have a long roots. Don’t plant the seeds too deep, because they need plenty of light and warmth to germinate and grow ( at 70 degrees within 14 days our southern Curassavica will break the soil surface, Syriaca and Speciosa may take another 2 weeks).Common milkweed is supposed to be easy and can also propagate well. The only time I’ve successfully transplanted milkweed has been during spring when they’re just starting to sprout. Make sure you dig deep (and wide) so you can get the whole rhizome. I have had TREMENDOUS success transplanting common milkweed.These native milkweed are perennials, meaning they come back year after year. Their aerial parts (flower, leaves, stem) die back but their rootstock remains alive throughout the winter.For milkweed species with rhizomes, propagation by cuttings of the tuberous rhizome is also easy and reliable. The cuttings should be made when the plant is dormant. Each piece of the rhizome should have at least one bud (they are about two inches apart). Timing of propagation is important.
Why is milkweed so hard to grow?
Milkweed does not like competition from other plants when it’s starting out. You’ll also want to make sure the soil around your seedling is free of debris, as milkweed love having warm soil. Under most conditions, when a common milkweed stem is cut off near ground level, in about two weeks a new shoot will appear from the roots. These new shoots are highly attractive to female monarchs, receiving two to 10 times more eggs than older stems.A light watering each day until roots are well established (7-10 days), preferably in the morning, should be sufficient. All milkweeds are perennials and some can be grown from cuttings.Milkweed can be cut and the rhizomes can be dug up. Physical control is difficult because it can re-establish from remaining seeds or rhizomes. Tillage of the soil in the area can be effective if it runs deep enough to destroy the roots.Milkweed is very difficult to transplant due to its taproots. Robyn advises trying to find the smallest plant you can (with the smallest taproot), or finding a pod to harvest seeds from and planting them.

When growing a crop like milkweed, soils are covered for a long period of time.
