Water: Olympic mullein thrives in moderate watering with good drainage, preferring dry to medium moisture levels, indicative of drought tolerance. Weekly watering maintains balance, making it ideal for gardens prioritizing water conservation, especially in temperate regions with seasonal rainfall.

Fertilize: Olympic mullein benefits from balanced fertilizers for robust growth, with monthly feeding during the growing season recommended. Limit applications during dormancy to avoid over-nutrition. Gradual-release formulas are ideal to prevent shock, and adjustments should be made based on olympic mullein's health and environmental conditions.

Pruning: Olympic mullein features tall, woolly stems and vibrant yellow flowers. Prune in early spring to remove dead growth, and again in late spring to shape and promote blooming. Cut back spent flower spikes for re-blooming and better air circulation. Use clean, sharp tools for effective pruning.

Propagation: Renowned for its tall yellow blooms, olympic mullein is a robust perennial that thrives when propagated by division. This method encourages vigorous growth, allowing gardeners to expand their displays or share with others, integrating seamlessly into routine plant care for sustainability.
