Water: Carolina milkvine thrives in moderate rainfall, requiring consistent watering weekly. It is not overly thirsty nor drought-tolerant. As an outdoor vine, it adapts to seasonal changes, absorbing more water during the rainy season to support vigorous growth.

Fertilize: Fertilize carolina milkvine with balanced NPK fertilizers every two months during active growth in spring and summer. Use half-strength liquid fertilizer to avoid root burn. Apply at the base and water thoroughly, reducing application in fall and ceasing in winter for optimal health.

Pruning: Carolina milkvine is a climbing perennial vine with heart-shaped leaves and star-shaped flowers. Prune in early to late spring to remove dead stems, control shape, and enhance air circulation. Consistent pruning boosts growth, ornamental appeal, and reduces disease risks, ensuring a healthy garden presence.

Propagation: Carolina milkvine is a climbing plant best propagated by sowing seeds. Scarify or soak seeds overnight for improved germination. Use well-draining soil, space seeds adequately, and provide support structures. Regular watering is essential, but avoid waterlogged conditions to prevent root problems.
