How to Care for the Plant
Water
Keep well-watered.
Pruning
Japanese spirea should be tip pruned in late winter or early spring prior to bud swell and before the shrub leafs out. Also, at this time, remove any dead, damaged or diseased stems along with those that cross each other. To keep spirea looking great and to promote blooming, trim the plant at least twice per year.
Fertilizer
Most established plants grow best if fertilized with a light hand. Fertilize our specimen trees and shrubs just once -- in early spring -- with a light but even coverage of a balanced, granular fertilizer (such 5-10-10, 10-10-10, or an organic fertilizer).
