Hydrangea don't bloom, why?
I don't know if this applies to all hydrangeas or just certain varieties, but they bloom on last year's growth. So if you trimmed back any woody shoots from last year, just leaving this year's green shoots, you would have cut off all the flowering shoots.





Also, try feeding it a potassium-rich plant food - potassium encorages flowers and fruit.
Reply:Some types of hydrangeas have blooming lifelines of 3-5 years. After that they no longer bloom. Plenty of water and fertilizer helps though. I've also noticed that they seem do better on the North side of the house. Good luck. At least the foliage is pretty.
Reply:We cut off all the dead heads this spring and that seemed to stop it from blooming . The lady across the street said that is why it didnt bloom.
Reply:Try feeding the non bloomer plant food 15-30-15, or 10-50-10. Make sure the middle number is much higher than the other two.
Reply:We have had a hydrangea for 3 years and it hasn't bloomed yet! Two others bloomed the second year. It depends on the species, how much fertilizer is used, how deep the roots are, and how much it is watered. Some things are worth waiting for!
