Attributes of Arctic pearlwort

Growth Rate

During spring and summer, arctic pearlwort exhibits a moderate growth rate, which manifests in steady vegetative expansion. This growth pace facilitates an increase in the plant's basal rosettes, fostering resilience against harsh Arctic conditions. Such moderate growth also supports the annual flowering with the production of numerous minute, white flowers. Despite winter dormancy, arctic pearlwort harnesses the ample light and warmth of the active seasons to perpetuate its lifecycle.

Water: Arctic pearlwort flourishes in cool, moist conditions, thriving with consistent moisture from weekly watering. As an outdoor plant in alpine/subarctic regions, it is adapted to frequent rainfall and short growing seasons, efficiently utilizing available water during peak growth.

Fertilize: For arctic pearlwort, use a balanced (10-10-10) liquid fertilizer monthly during the growing season, switching to high-nitrogen every other month if needed. Apply one teaspoon per gallon, avoid winter fertilization, and water well after feeding to promote healthy growth and longevity.

Pruning: Arctic pearlwort thrives with spring pruning to remove dead stems and improve growth. Thin crowds for better air circulation, reducing disease risks. Regularly deadhead spent flowers for ongoing blooms, and always utilize clean, sharp tools to avoid infections.

Propagation: Arctic pearlwort can be propagated by sowing seeds with a high germination rate. Use a finely textured, well-draining medium, and ensure it’s weed-free. Water gently to maintain moisture. Consistent monitoring aids seedling emergence and establishes arctic pearlwort's unique traits in the garden.
