Water: Woolly groundsel thrives in arid environments, retaining moisture and preferring minimal watering, specifically weekly. Its succulent-like leaves indicate drought tolerance, ideal for xeriscaping. As a temperate outdoor plant, woolly groundsel adapts to seasonal rainfall, contributing to its low water requirements.

Fertilize: To ensure woolly groundsel thrives, use balanced NPK fertilizers bi-monthly during spring and summer, reducing frequency in fall and winter. Water the soil before application to prevent root burn, adhering to product guidelines for optimal growth and flowering health.

Pruning: Woolly groundsel, known for its silvery foliage and yellow flowers, benefits from early spring pruning. Remove dead or damaged stems to foster healthy growth, improve air circulation, and enhance flowering. Use clean tools and consider a balanced fertilizer after pruning for optimal results.

Propagation: Woolly groundsel propagates well from cuttings taken from healthy stems. Use a sterilized knife for a small cutting, remove lower leaves, and dip the end in rooting hormone. Plant in well-draining soil and maintain humidity for optimal growth, mirroring its natural alpine environment.
