I’ve had these Nikko Blue Hydrangea plants for YEARS. They bloomed the first two years, and after that, NOTHING. I cannot figure it out.
One Plant Guy told me to cut them down in autumn, and new blooms would appear in the spring. Nothing. Another Plant Guy told me to leave the shrubs alone (no trimming) and in time, they’d bloom. Nothing. GAH!
The plants are well-fed, they are obviously not starving. They have plenty of green growth. I’m out of ideas. Can anyone help?
