Some hydrangeas bloom on new growth that develops on old wood. If your hydrangeas generally freeze down to ground level each winter, you may never see flowers on your hydrangea. Other types such as Endless Summer do not need old growth in order to flower. Instead they can freeze down to ground level and will flower on the new growth of the season. Try to have your hydrangea identified to make sure yours will bloom on new growth regardless of the old growth. Other reasons for non blooming are lack of sufficient sunshine and pruning at the wrong time of the year. Hope this information helps!
