Viburnum – Failed To Bloom
Q: Our ‘Erie’ viburnum failed to bloom in May. Should it be pruned heavily? When?
A: Like mophead hydrangea, ‘Erie’ viburnum blooms on twigs that form the previous season. Your shrub’s flower buds must have been frozen off in winter. Don’t prune now. Wait until after spring flowering if the shrub needs pruning.
