Swamp Milkweed (Asclepias incarnata) is a beautiful Native plant that’s not only visually appealing but also serves as a crucial host plant for Monarch butterflies. It requires a bit more water than other Milkweed species, making it perfect for raised beds or containers.
Growing it in containers or raised beds offers a flexible solution for gardeners with limited space or those wanting to control soil quality. Here’s a guide to successfully cultivating Swamp Milkweed in such settings.
1. Choosing the Right Container or Raised Bed:
- Size: Swamp Milkweed can grow up to 3-5 feet tall. Ensure your container is at least 12-18 inches deep to accommodate the plant’s root system.
- Drainage: Ensure the container or bed has adequate drainage holes to prevent waterlogging.
2. Selecting the Soil:
- Soil Type: Opt for well-draining soil. While Swamp Milkweed naturally grows in wet conditions, it doesn’t like to be waterlogged.
- pH Level: Aim for a pH level between 6.0 to 7.5. Regular garden soil mixed with some compost should suffice.
3. Planting:
- Purchase Johnny Butterflyseed’s Swamp Milkweed Seeds.
- Spacing: If planting multiple seeds or seedlings, space them about 18-24 inches apart to allow ample room for growth.
- Depth: Plant seeds about 1/4 inch deep in the soil.
