Hydrangea Poor Blooms
So I just bought my new house last year and I have 3 hydrangeas which were covered in huge blooms. We had a horrible winter and a late spring freeze and 2 of the three bushes started from the ground up as the old wood was dead. The 3rd bush produced blooms but only patchy flowers. I think it may be a lace cap hydrangea but it does not look anywhere how it did last year. I wonder if it has to do with he bad winter. Anything I can do here?
