Water: Hopi tea greenthread, originating from arid regions, thrives on minimal moisture with high drought tolerance. Watering once per week suffices without excess saturation. Preferably cultivated outdoors, it benefits from natural rainfall and flourishes in well-draining soil that resembles its native habitat's drainage.

Fertilize: For optimal growth, hopi tea greenthread needs balanced fertilizers high in nitrogen, phosphorus, and potassium, applied quarterly in light amounts to avoid over-fertilization. Fertilize during spring and summer for robust development, reducing application in winter. Ensure thorough watering after applying and follow guidelines for safe use.

Pruning: Hopi tea greenthread features bright yellow flowers and fine foliage. Regular pruning in early spring and late spring promotes healthy growth and further blooming. Deadheading spent flowers throughout the season enhances blooming, while pruning improves air circulation and prevents legginess for a vigorous appearance.

Propagation: Hopi tea greenthread is a perennial herb appreciated for its yellow flowers and use in herbal tea. Propagate by surface sowing seeds after frost, in sunny, well-draining soil. Maintain moderate temperatures and moist soil for germination. Once established, hopi tea greenthread is drought-tolerant and low-maintenance.
