Water regularly once established, allowing the soil to dry out slightly between waterings. In containers, ensure good drainage and water when the top 2-3 cm of soil feels dry.

Reduce watering during winter dormancy to prevent root rot.

Prune back dead or damaged stems in late winter or early spring before new growth appears. Remove spent flower stalks to encourage reblooming and prevent self-seeding if desired.

Cut back to the ground in fall after the plant has finished blooming and seeds have dispersed.

Seeds can be sown in fall outdoors or stratified indoors in a cold, moist environment for 30-60 days before spring sowing. Division of established clumps can be done in early spring.

Sow seeds outdoors in fall for best germination results.

Container-grown Asclepias ovalifolia typically benefits from repotting every 2-3 years. Repot in early spring before new growth starts.

Choose a pot that is slightly larger than the current one and use well-draining potting mix. Avoid disturbing the roots excessively.
