Expert tips
The key tip
Prune this spiraea just after flowering to prepare next year's flower buds.
The common mistake
Pruning in autumn or winter: winter pruning removes the flower buds that have already formed.
The pro's trick
Keep pruning very light: just remove dead wood and crossing branches, without changing the overall shape.
Care
Exposure
Place your spiraea in full sun for optimal and abundant flowering. It also tolerates partial shade, but with fewer flowers. Avoid overly shaded areas that slow growth.
Watering
Water regularly after planting to establish the root system well. Once established, spiraea tolerates dry periods well thanks to its moderate water needs. During prolonged drought, water deeply once or twice per week.
Soil
Spiraea adapts to most soils, even poor or slightly chalky ones. Prefer well-draining soil to avoid waterlogging. Adding organic matter at planting promotes establishment.
Pruning and form
Prune after flowering (May-June) to maintain a nice compact, bushy shape. Remove dead or diseased branches in late winter. Light pruning is sufficient; this spiraea branches naturally and flowers on the previous year's wood.
Fertilizer
Apply balanced fertilizer in spring (before flowering) to stimulate growth. Well-decomposed compost or fertilizer for flowering shrubs works perfectly. No excess needed: spiraea thrives without intensive feeding.
Pests and diseases
Spiraea is very robust and seldom affected by diseases. Occasionally watch for aphids in spring, which can be treated with water spray or horticultural soap. Good air circulation prevents fungal issues.
Did you know?
Spiraea prunifolia is called 'Japanese spiraea' and bears the poetic nickname 'snow flower' because of its tiny white flowers in dense clusters that cover the shrub in spring. In Japan, it symbolizes discreet elegance and has been prized in traditional gardens for centuries. Its name 'prunifolia' means 'plum leaves,' comparing its fine, elongated foliage to that of fruit trees.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
