Late-season cuts can stimulate new growth that may not harden off before frost, and may also remove next year’s flower buds on old wood types.Skip summer pruning to avoid cutting off this season’s and next year’s blooms. Water deeply in the morning and don’t bother deadheading—hydrangeas don’t need it.If the air temperature doesn’t go below 0 degrees (zone 7) there is no need for winter protection.
