I will post a picture here of one of my hydrangeas. I bought a house with many of them and it’s unclear to me which are supposed to bloom on new wood only vs old and new wood. Several have tall bare branches while growth appears below the tall ones with green leaves. Should I assume these should be cut back to eliminate the old wood? Or is it too early her in Central NJ in early June to know if growth will appear on the old wood? Thanks.
