Water regularly, keeping the soil consistently moist but not waterlogged, especially during warmer months. Ensure well-draining soil rich in organic matter. Fertilize lightly in spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further blooming. Prune back foliage in late fall or early spring to maintain shape and remove any dead or damaged growth. Provide adequate humidity, especially indoors, using a humidifier or placing the plant on a pebble tray filled with water. Monitor for pests like aphids and spider mites, and treat promptly if detected. Repot every 2-3 years as needed.
How do I propagate Meadow Rue?
