Soil Type
Water: Spirea 'Grefsheim' originates from temperate regions and prefers moderate moisture, thriving in well-drained soil. Water twice a week for optimal hydration. As a deciduous outdoor plant, spirea 'Grefsheim' sheds leaves during dry periods and enters dormancy to conserve resources.
Fertilize: To ensure spirea 'Grefsheim' thrives, apply organic fertilizer in winter or early spring. Use foliar fertilizer monthly during growth, phosphorus-potassium fertilizers 2-3 times during flowering, and organic fertilizers post-bloom. Create a 10 cm (4 inch) deep fertilizing ditch around the crown and water well afterward.
Pruning: Spirea 'Grefsheim' features cascading white flowers and requires annual pruning in early spring to maintain shape and encourage growth. Remove weak branches and thin stems for better air circulation, enhancing blooms and controlling size. Make clean 45-degree cuts close to buds to prevent disease.
Propagation: Spirea 'Grefsheim' propagates well through cuttings, particularly semi-hardwood ones taken during growth. Use rooting hormone and a well-draining soil to encourage rooting. Maintain consistent moisture and provide sufficient light and warmth, ideally in a protective environment like a cold frame or greenhouse.
