Know which type of hydrangea you have: Arborescens, Macrophylla and Paniculata.
Arborescens varieties include: Annabelles, Snowhill and Invincibelle Spirit.
*** When pruning this variety, it is best to trim down to ground level.
Macrophylla varieties include: Endless Summer and All Summer Beauties
*** You will want to cut back the winter damage and cut back the stems to live buds.
Paniculata varieties include: Pee Gee, Quick Fire, Tardiva, Limelight, Little Lime and Pinky Winky.
*** Do not just trim off the top of the shrub, prune back 1/3 of the shrub into the body of the plant. Remove duplicate branches.
