Where are the flowers on my hydrangea?

[susan austin]

I have a very healthy Hydrangea in a large tub (2 years old) but this year it only has one flower, I have fed and kept it watered, also protected in the winter as we are in Scotland. Could anyone help by explaining why?

When your hydrangea won’t bloom, it is because of the species of hydrangea you have planted. Some of them grow flowers off of new wood and some of them will grow flowers off of old wood. If your hydrangea won’t flower, then you need to figure out if this is the variety you have planted.

Thanks for that information. The hydrangea in question is: Cityline Nizza (ranice). Is that of any help?

Hydrangea macrophylla Nizza = 'Ranice' Macrophylla flowers on old wood. So perhaps you have a severe winter and either the old woods have died down and new woods won't flower. Or a hard frost descended on your buds when they tried to develop. Or you have pruned them. Remember, don't prune unless they are very big.

The other link shows you how to overwinter the plant to protect the whole plant and to protect the buds.

Now that you know it is macrophylla, if you watch the videos again, you will have a much better picture. You have helped me learn all this information. I didn't have a clue before I attempt your question. I am no expert. I'm nosy, bossy and am not much good at web design and hence I welcome all distractions. LOL!

Did you Prune it vary hard?.......... That is often the reason Hydrangeas don't flower. They are best left To grow to there desired Size with vary little Pruning. If & when you Do it is best done in March in the UK & only Prune to help Shape & help it dense up if desired

Thanks so much alp for all the info. I believe the problem was the pruning, there were no buds and although we had some nights
minus 10 in Scotland I did wrap it up quite well. Anyway will study the video tomorrow.
Keep being bossy and nosy

I’m growing “Endless Summer “ Hydrangeas here in zone 5.
Out of at least 15-20 well-established plants, only two have bloomed.
We have a wooded lot around the garden, and the Hydrangeas had always been happy in the past in part sun/part shade.
This variety blooms on old and new wood. The leaves appear dark green and healthy.
We have arborists to trim, feed and treat any unhealthy trees.
I’m wondering if the fertilizer that is being injected into the ground is not the proper ratio for Hydrangeas.
Ive not had any problems with any other floweing perennials.
Do Hydrangeas sometimes take a year off from blooming to restore their energy reserves?
Also, we only prune out dead wood after the plants have fully leafed out.

Someone probably has done a very good promotion for the plant!

Also, have a look at the videos on this page

I need to watch Medical Detectives. Will come back tomorrow!

Think this video is most useful. Might be a good idea to lay off the pruning and add a bit of fertilisers in Spring. Also, did you have frost last winter? Frost can kill the developing buds!
