Why are my mophead hydrangeas not blooming?
Often, hydrangeas that aren’t producing flowers have been pruned in early summer and late winter. If they are over pruned, they’ll have a tendency to die back more than normal, and they’ll make you wait a whole year before they blossom again. Remember, it may need that old wood in order to bloom.
What to feed hydrangeas to make them bloom?
Hydrangeas will benefit from an all-purpose, balanced fertilizer, such as a 10-10-10 N-P-K, that contains equal amounts of each nutrient. A balanced fertilizer will encourage healthy foliage as well as bountiful blooms.
How do I make my hydrangea bloom purple?
Generally speaking, acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.
Why are my hydrangeas not leafing?
If the stems die off and do not leaf out, the plant may generate stems from the crown/base. Apparently though, it has not quite decided what to do so -leaf out or generate new stems- so wait some more time. A hydrangea shrub that has not leaf out by late May probably did not make it.

Do coffee grounds change the color of hydrangeas?
Some gardeners report success in turning their hydrangeas blue by applying coffee grounds to the soil. The coffee grounds make the soil more acidic, allowing the hydrangea to more easily absorb aluminum. In addition, fruit peels, lawn clippings, peat moss and pine needles, are thought to have a similar effect.
