Q.It’s Fall, And I Need To Identify This Type Of Hydrangea.
I have never pruned this hydrangea nor has it ever bloomed. I planted it from a bag of purchased bare root plants labeled HYDRANGIA but have forgotten the variety. Should I remove some of the stems next spring? How to care for it so it will bloom.

If you don't know the variety, it's best not to prune till it blooms. For example, the mophead hydrangeas have the big round blooms that will be pink or blue depending on soil pH. The oakleaf hydrangea has the characteristic leaves in the shape of oak leaves. (It's not that one, according to photo.) Mopheads' buds are formed the previous summer so it's important not to cut those off when pruning.
Here are tips on how to get your hydrangea to bloom, then you can see the bloom shape and color and better determine when to prune.
