My incessant summer hydrangeas be contained by bloom when planted 2 yrs ago but never bloomed again. Anything I can do? I am so disappointed because I was really counting on the color...
I am so disappointed because I was really counting on the color to even out my sunny garden. I would love to get them to bloom. I've tried coffee grounds, miracle grow, etc.. I am giving it a new season and then I may yank them. Any philosophy to help them bloom this season would be greatly appreciated.
The most common reason for hydrangeas not blooming is 1) pruning at the wrong time, and 2) not enough sun.
Also - don't fertilize - often that will rouse a lot of leaves, but not blooms.
They may be phosphorous deficient. Also, when pruning, don't mistake dormant-but-alive stalks with the truly unmoving old bloom stalks.
As an aside.. if you want to have blue blooms, nurture them with aluminum sulphate.
Here is a great question & answers website:

When this happened to mine, I found out that I be not pruning them correctly. Last year I didn't prune them at all and this year they are full of flowers. prune them down a little. may promote some blooms
Answers: The above answers are all correct. One entry they have left out is the weather. My hydrangeas did not bloom at adjectives last year.all leaves. The defence is they started leafing out in the spring and we received a cold snap in the spring that kill the buds. Hydrangeas are notorious for blooming some years and not blooming or very little blooming the subsequent. This year has been fantastic for my hydrangeas as the spring be mild and stayed mild until summer. Just be sure to pay close attention to the weather and your hydrangea in the spring. If they are starting to branch out or the buds are turning green and you get a cold snap then your hydrangeas probably won't bloom.
Try giving your hydrangeas a shot of bone collation (about a cup per plant) in the spring before they palm leaf out. This will give them a big shot of phosphorus without the nitrogen to gladden blooming of your plants. Don't give up on them yet...I know they can be frustrating plants but when they bloom its worth the dawdle!
I included pictures of my hydrangeas.
