Spirae japonica late pruning
I got to look after some spirae japonica. From diverse sources I found out just recently that they need pruning in late spring. However, when I started looking after this garden I thought they needed to be pruned in autumn like many shrubs ... In short, I missed the deadline and didn't even deadhead them! They've been long established and are a bit too prolific. Could I simply cut them hard back this winter then prune them the 'proper' way not next spring but the spring after that?
