Care
Watering
Keep the soil consistently moist, especially during spring growth and summer. Avoid prolonged waterlogging, which promotes rot. A mulch aerates the soil and preserves natural moisture.
Exposure
Choose light partial shade or north-facing exposure. Full sun, especially hot afternoon rays, dries the soil too quickly and causes flowers to wilt. In mountain regions, the plant tolerates more sun.
Soil Preparation
Enrich the substrate with compost or peat to increase moisture retention. Proper drainage remains essential to prevent fungal diseases. Slightly cool, moist soil is ideal.
Pruning and Maintenance
Remove spent flowers to extend the flowering period. In late autumn, cut the foliage to ground level after it fades. Light cleaning of damaged leaves improves appearance.
Fertilization
An application of well-decomposed compost in spring is sufficient. Avoid excess nitrogen, which promotes foliage at the expense of flowers. A well-fed plant blooms more abundantly.
Diseases and Pests
Watch for powdery mildew and rot if humidity is excessive or air circulation is poor. Occasional pests like aphids may appear. Good hygiene and ventilation reduce risks.
Did you know?
Ranunculus aconitifolius is nicknamed 'Silvery Buttons' or 'Cuckoo Flower' in the Alps, where it blooms at the same time as the cuckoo's call in spring. Its delicate double flowers resemble miniature roses, making it a prized collector's plant in Renaissance gardens.
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.
