Water: A young japanese muhly requires frequent watering for active growth, while established plants are drought-resistant, needing water only during severe dry spells. Water when the top soil is dry, as japanese muhly does not thrive in soggy or waterlogged conditions.

Fertilize: To enhance growth and blooms of japanese muhly, apply slow-release fertilizer in spring and mid to late summer, especially in poor soil conditions. Dilute balanced fertilizer by half before feeding to optimize plant health and flowering potential.

Pruning: Japanese muhly is an ornamental grass valued for its arching blades and flower spikes. Prune in early spring by cutting back to 2-3 inches to encourage growth. Regular trimming prevents overcrowding, improves air circulation, and reduces disease risk. Use sharp tools for clean cuts to promote recovery.
