Water: Yellow woodsorrel has medium water requirements; avoid sogginess. Water when the top inch of soil is dry, ensuring the top 2 inches remain moist. Use rainwater if possible, though tap water is acceptable if not too hard or cold.

Fertilize: Yellow woodsorrel is a light feeder and thrives in balanced soil without much additional feeding. Use a half-strength balanced liquid fertilizer every few months, avoiding nourishment during winter dormancy. When repotting, incorporate organic compost to enhance growth during the sprouting period.

Pruning: Yellow woodsorrel needs pruning during winter dormancy, indicated by withering foliage. Remove brown leaves, as this is normal; they will regrow in 2 to 4 weeks. Always disinfect pruning tools to prevent cross-contamination.

Propagation: The optimal time for yellow woodsorrel propagation is winter during dormancy. To propagate, remove yellow woodsorrel from its pot and gently separate the bulbs by hand. Subsequently, place the separated bulbs into new containers for growth.
