Pinewoods Milkweed is limited to the southeastern United States and areas with well-draining sandy soil, thus is not considered an invasive weed. Like with other milkweeds, all parts of pinewoods Milkweed are toxic due to presence of cardiac glycosides, although the specific toxicity for the species is not well established. In general, livestock is in greater danger of poisoning than humans. The milky sap causes skin irritation in humans. It should be noted that, despite its toxicity and sometimes unwanted appearance on properties, pinewoods Milkweed is a significant plant for the survival of many butterflies, including the iconic Monarch butterfly.

Water:
Pinewoods Milkweed thrives in sandy soils and prefers consistent moisture, requiring weekly watering to replicate natural rainfall. As an herbaceous perennial, it benefits from regular watering during its active growing season. Indoors, pinewoods Milkweed thrives in a humid environment to mirror its native conditions.
Fertilize:
Pinewoods Milkweed requires minimal fertilization, needing a phosphate boost at flowering and organic fertilizer before winter to enhance cold tolerance. During dormancy, fertilization should cease to prevent root rot from overfertilization, as the plant's physiological activities slow significantly.
Pruning:
To maintain pinewoods Milkweed health, regularly remove infected plants and wilting leaves. In tropical or subtropical climates, trim branches in early spring to encourage growth. Due to pinewoods Milkweed's high toxicity, wear gloves when handling, keep it away from children, and avoid ingestion.
Propagation:
In early spring, pinewoods Milkweed produces multiple small seedlings. To propagate, dig up the seedlings and use a sharp, clean knife to divide the roots into parts, then plant them separately.
