詳細養護說明
Light & water
Avoid hot western exposures. Mulch to hold moisture during summer heat waves.
Color
Acidic soils favor blue (with aluminum available); alkaline soils favor pink. White types stay white.
Pruning
Many mopheads bloom on old wood — prune lightly after flowering, not hard in spring.
Winter
Protect buds in cold zones with wraps or plant reblooming cultivars.
