What happens if you don't prune hydrangeas

If you’re asking ‘should I cut back hydrangeas in the fall’ the answer depends on the type of hydrangeas in question. Hydrangeas can broadly be split into two groups: those that bloom on old growth and those that bloom on new growth.

The age of the stem that sprouts the hydrangea blooms will determine whether you should cut back hydrangeas in the fall or leave them well alone during the fall months.

Once you've found out when to prune hydrangeas, it is also vital that you know how to prune hydrangeas and when to deadhead hydrangeas.

'Pruning can improve the plant’s vigor; prune ones that bloom on old growth – lacecap, mophead, and oakleaf – after flowering, and in spring or fall for ones that bloom on new growth – paniculata and arborescens,' explains garden expert Leigh Clapp.
