My Blue Hydrangeas Won’t Bloom!

August 7, 2009

Gardening, summer

I’ve had these Nikko Blue Hydrangea plants for YEARS. They bloomed the first two years, and after that, NOTHING. I cannot figure it out.

Non Blooming Hydrangeas

One Plant Guy told me to cut them down in autumn, and new blooms would appear in the spring. Nothing. Another Plant Guy told me to leave the shrubs alone (no trimming) and in time, they’d bloom. Nothing. GAH!

The plants are well-fed, they are obviously not starving. They have plenty of green growth. I’m out of ideas. Can anyone help?

    Nope. I’ve got 2 hydrangeas that have never bloomed. Ever. They are lovely and green, but never ever bloom. I do cut them back every year, but still–nothing. If you find out the secret, let me know. :)

    That is quite mysterious. On possibility to try is looking at what fertilizer you’re using. If it’s too high in nitrogen and not enough of the other 2 numbers all energy may be going into leaves and not enough proper nutrition for flowers? Ask you garden center or extension office for advice about fertilizing bushes. Another possibility, together with this one, is does this get enough sun? Some plants won’t bloom without enough light over a given day, but will grow leaves just fine.

      Rebecca and WillOakStudio- thanks for your input! I don’t fertilize them at all. Maybe that’s the problem. They do not get full sun at all. They did bloom the first two years I had them in this location, though. Your comments are food for thought. I will fertilize them in the spring (I read that they shouldn’t be fertilized after July, their blooming season). And if they still do not respond by next year, I will have the kids move them move them to a sunnier spot by autumn. :D

      Thanks!

    The planting location is important. In the northeast they usually do well when planted where they get full sun.

    I had the same problem. After several years of trying this and that and moving it around the yard, I came up with a solution: I ripped them out and burned them. That’ll teach ‘em not to bloom! :)

    I have two like this near each other. They are in mostly shade and our soil leans toward acidic which they love (make the flowers turn blue). So, I cut one way back one year and it took a few years to bloom again. The other I only cut the dead branches from. I think if you are patient the blooms will come back. This type blooms on old growth. There are some that bloom only on new growth. Good luck!

    Bad advice whoever told you to cut them in the fall. You really should never have to prune a hydrangea. If/when you feel the need to, you should only do it immediately following bloom time, and only cut the blooms off. Never, ever cut the old wood as that is where they bloom from. I’ve seen people who hacked, er pruned their hydrangeas and they never bloomed again after that. Another reason could be lack of sun, but I bet you ruined them when you pruned them. I’d toss them and start over. I mean after all, you don’t grow Hydrangeas for the lovely foliage.

      Hi Maria.

      Well, I did get a few more blooms this year… I think it may have something to do with lack of sun, as the blooms only showed in areas where they got sun. SHEESH and I thought hydrangea was a shade-loving shrub. :-p

    We have lived in our home for 5 years and during those years, our hydrangea bloomed every year. It has been in the same location and never fertilzed it. Last autumm, our yard man pruned it back. No blooms this year. Apparently, after reading other comments, the pruning it has caused the fact that we did not have any blooms. Does this mean we will NEVER
