The caltha genus, often referred to as 'Marsh Marigold', generally needs a moist environment, partial to full sunlight, and cool temperatures. The soil should be consistently wet, nutrient-rich and slightly acidic. Caltha plants face common challenges such as leaf spots, powdery mildew, and attack by pests like aphids and slugs. Seasonal considerations include ensuring adequate water supply during summer due to heightened evaporation, whilst preparing for a dormant phase in winter. Pruning in late autumn promotes healthy regrowth in spring.
