How and when to prune Endless Summers
What is the proper way to prune these hydrangeas and when is the proper time?
I have three Endless Summer Hydrangeas right next to each other. I bought these plants at the same time about 3 years ago. The light conditions are basically the same for all. Not sure about the soil as one bloomed lavender-blue.
The first in the row bloomed earliest (April) and was covered with flowers.
The second bloomed slightly later(May) and with not as many flowers
The third had one bud develop in June is just now getting lots of buds (September).
I pruned the first two after the flowers started looking bad but I'm not sure I did it right. I went down to first set of leaf buds. I can't remember what I did to them last year, but I wonder if I got them out of sync last year.
After pruning the two, all three are about the same size.
Any advice on what to do now?
