Hi Helen and welcome to GoY, a photo would be a big help in seeing if there is a problem.

A photo will definitely be helpful. How long has he had it? Does it get full sun? I can tell you the primary reason for cherry trees not blossoming is it's location. They must be in full on sun for a minimum of 6 hours per day. Anything less & they will not be able to set blooms.

Bathgate it sounds as it this ornamental cherry ddi flower until it was pruned by a 'professional' oh, and when we had an ornamental cherry there was no way it ever got full sun for 6 hours a day. As far north as we nothing gets that amount of 'full' sun even in the middle of summer.

How big was it when it was pruned and how much growth was removed, any idea? Photo would be very useful indeed...

I know 6 hours of sun in your location is a "pipe dream." This could be part of the problem. Would a "professional" know the fundamentals of tree pruning? We simply need to know more about the this conundrum. Are the two factors even related? How long has it been since it flowered last?

I don't know how it is in the UK, but, sadly, around here, anyone with a pickup truck, a pole saw, and a rubbish bin can call themselves a "professional". Hiring a Certified Arborist, is usually better, but is still not a guarantee. I personally know a Certified Arborist who knows from nothing--or, perhaps, just doesn't care--though the vast majority are quite careful and capable. As I said, the nomenclature and qualifications may be different in the UK.

Bulba and I have watched so called 'professionals' absolutely butcher trees... Wouldn't trust any of them as far as I could throw them - sorry Helen.

It isn't different here Tugbrethil - finding a reputable, responsible Tree Surgeon is just as tough, there's plenty of tree crews running around who hack trees badly - even our Local Authority sends out cowboys, you should see the state of the horse chestnut in the gardens here after being 'pruned'. It looks okay in full leaf, but is hideously ugly in winter when the branches are bare, its been so badly cut.

It is sickening at times Bamboo, I agree...

Helen, we really do need a photo to make any informed statement or suggestion.

It's a bit late now, but its important when choosing tree to check the height at maturity - tall ones pruned to a smaller size rarely look good.

Mg. My gardener used the weed wacker on my tulips & daffodils. They he worked them over with the leaf blower. ::

I'm not surprised... much as Bulba needs help in the garden now we'll never take anyone on!

That's one job I prefer to do myself. I don't mind the physical labor at all and I don't have to worry about my gardener pulling up my plants he thinks are weeds. Thanks for letting me vent, lol!

Ah but I think you are a little younger than us Bathgate and, currently, due to health issues I can't garden at all :(

Oh I didn't know that. I'm sorry. In your case a knowledgeable gardener is worth his weight in gold.

You and Bulba is... there are too many wee alpines in the garden to let anyone else loose!
