Water: Yellow wild indigo thrives in dry conditions followed by rainfall, preferring moderate moisture and tolerating short droughts due to deep roots. Water weekly to prevent over-saturation. Grown outdoors, yellow wild indigo requires full sun for optimal growth and efficient water use during its active season.

Fertilize: For optimal health, yellow wild indigo requires balanced fertilizers and occasional high phosphorus mixes for flowering. Fertilize in early spring and midway through the growing season, using a light hand to avoid overfertilization. Adjust based on the plant's lifecycle, following dosage instructions to prevent root burn.

Pruning: Prune yellow wild indigo in early to late spring to remove dead stems and promote new growth, enhancing airflow and reducing disease risk. Trim spent flowers for tidiness and reblooming potential. Light shaping is preferable; avoid heavy pruning for optimal health, as per horticultural guides.

Propagation: Yellow wild indigo is a hardy perennial with yellow flowers and bluish-green leaves. Propagate through softwood cuttings taken in late spring or early summer. Ensure at least two nodes are present, apply rooting hormone, and plant in moist, well-drained soil while preventing saturation.
