Water: Drought-resistant varieties of japanese yellow sage need minimal watering, only during drought. In contrast, tender varieties and young plants require regular watering of about 2.5 cm (1 in) every 7-10 days to prevent soil from completely drying out.

Fertilize: Japanese yellow sage thrives in rich or clay soils without fertilizer. In poor soils, a slight addition of compost or slow-release fertilizer is beneficial. Avoid excessive fertilizer to prevent rapid, weak growth.

Pruning: Japanese yellow sage thrives in shade, showcasing yellow flowers and sprawling foliage. Prune in early spring to promote growth and reduce legginess. Regular pruning enhances air circulation, mitigates disease risks, and fosters vigorous blooming. Use clean, sharp tools for effective and healthy cuts.
