Description : My climbing hydrangeas 6-7 years old do not bloom at all
Last Answer : Raise the soils Ph level up just a smidgen, you can do this by using common white vinegar. Add (to start out with) one cup of vinegar to at least 4 gallons of water, 3 times /week, ... might go into shock; the higher the Ph Levels in the soil for hydrangeas the better chance that it will bloom
