Common Questions
Is swamp milkweed invasive?
When grown in its natural habitat in the eastern U.S. and Canada, swamp milkweed is not considered invasive. However, it does tend to spread, so if this is a worry, consider planting it in a container or a spacious planter.
Should you deadhead swamp milkweed?
Removing spent flowers is not necessary but can be done for. neater appearance and it can prolong the bloom.
Why isn’t my swamp milkweed blooming?
If your swamp milkweed is not blooming, it might be due to the plant's young age. Milkweed may not produce flowers in its initial year as it focuses on root development. Additionally, an abundance of nitrogen in the soil, like runoff from a fertilized lawn, can hinder blooming. Also, plants experiencing drought, heat stress or not enough sunlight will also fail to blossom.
Can I grow my plants in containers?
Yes, swamp milkweed is pretty easy to grow in a container. Use a container at least 14 inches in diameter with good drainage holes. Terra cotta works great due to its heavier weight. Use regular commercial potting mix and blend with vermiculite or extra perlite to improve drainage. Plants will need watered regularly in containers. Re-pot when roots start to grow out of drainage holes.
