Hydrqangeas aren't blooming
Recently we did some landscaping and put black mulch around all our plants. My hydrangeas have been in this location 3 years & put out pink flowers. We also cut down a tree and the plants get a lot more sun & appear to be much heartier (2x/the size also). They get lots of water & look good. But we have no blooms this year.
My lime hydrangeas have the same oil around them and they are all blooming. Too much sun? Any ideas?
