How to keep Cardamine Trifolia.
Light
Trefoil cress originates in habitats such as forest understories or rocky areas, where it grows under natural shade. It prefers partial sun but can tolerate both full sun and full shade, demonstrating its versatile and hardy nature.
Water
Trefoil cress flourishes in moist, humid conditions and thrives in soil that is consistently damp but not waterlogged. To ensure optimal growth, it's important to water it weekly. Being an evergreen perennial, trefoil cress retains its foliage throughout the year. During the growing season, it needs careful watering to maintain its lush leaves.

A single fertilizer application in spring is typically enough for Trefoil cress, though repeated feedings can boost growth. Feed once every month to a month and a half. Fertilization improves the leaves' appearance and function, helping maintain even color and a healthy texture. It also encourages root development and nutrient uptake for long-term plant health.
Pruning
To maintain the shape and health of trefoil cress, prune it from early to late spring. Remove any dead foliage and trim back leggy stems to encourage new growth. Regular pruning enhances air circulation, which helps prevent disease. Be sure to use clean, sharp tools, and avoid heavy pruning during the main growing season.
