why no blooms
There are 9 hydrangea plants, 3 bloom a blue bloom on the cool side of each plant. There are 6 other hydrangeas with in 75 yards that produce no blooms but have large leaves.
Of these 3 receive about 7 hours of sun and the other 3 receive about 4-5 hours of sun and much light reflected from a 6 story building. What could cause the plants to show no blooms? Could it be too much water is supplied from an irrigation system? Your help is greatly appreciated. Also this happened last year too.
