How to prune japanese spirea 'goldflame'

Late winter to early spring before new growth; deadhead after bloom. Cut all stems back by one-third in late winter using clean bypass pruners. Remove dead, crossing, or weak interior stems entirely. After flowering, shear off spent blooms lightly to promote a second flush later in summer.

Annually in late winter; deadhead after each bloom flush. Spiraea japonica 'Goldflame' blooms on new wood, so late-winter to early-spring pruning maximizes flowering. Cut the whole plant back by one-third before new growth emerges, then deadhead after the main flush to encourage a second round of blooms. Hard renovation — cutting to 6–12 inches — is tolerated if the plant becomes woody.
