Care
Watering
Water moderately during the growing season, making sure not to let water stagnate at the crown. In winter, reduce watering. Prefer light, regular watering rather than excessive soaking, particularly in containers.
Light Exposure
Place your round-leaved saxifrage in part shade to partial shade. It also tolerates moderate sun in cool climates, but avoid direct, scorching exposure during the hot hours of summer.
Soil Preparation
Prepare a well-draining substrate made of potting soil, gravel, or pumice to improve aeration. In garden beds, enrich the soil with well-decomposed compost and ensure good drainage to prevent root rot.
Pruning and Cleaning
Regularly remove dead or damaged leaves to maintain a compact shape. Remove spent flowers to encourage new blooms.
Fertilizing
Apply balanced or diluted fertilizer in spring. This alpine species doesn't need heavy feeding; a yearly addition of rich potting soil is usually sufficient.
Diseases and Pests
Watch for powdery mildew in warm, humid conditions. Root rot can occur if soil stays wet in winter. Prevent problems by ensuring good air circulation and optimal drainage.
Did you know?
The round-leaved saxifrage owes its Latin name 'rotundifolia' to its distinctive coin-shaped leaves. This alpine plant thrives in rocky crevices and mountain fissures, where it has developed a remarkable ability to root in mineral-poor spaces. Its common name 'saxifrage' literally means 'stone-breaker,' because medieval botanists believed its roots fractured rocks!
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
