I have three Nikko Blue Hydrangeas that used to bloom beautifully, but this year there are very little blooms, and most of them are near the bottom of the plants. The mop heads that bloomed are just as large as ever, but nowhere near the quantity of blooms we're used to seeing.
Any idea why this might have happened? We're wondering if the warm spell in the Spring and then a cool down (possibly even a freeze) might have contributed to the problem. We have other varieties of hydrangeas that performed well this year, but the Nikko Blue's were disappointing.
Linda, it depends on where you live if they prefer shade. If you are in the south where there are hot summers, then it is a good idea to put them in the shade. But I am in the midwest, in zone 5 and I have hydrangeas on the east side of my house and they get morning sun and do just great.
