We have two trees in our back garden that I am fairly sure are Sorbus aria Lutescens. They are about 12 years old and have reached a height of approx. 20 feet.

They have been planted on the boundary of our garden and very close to a tall, dense hedge of very mature trees, which we trim when they start encroaching onto our garden. Because of this hedge, our Sorbus aria trees have all their branches growing out over our garden and nothing on the other side that faces the hedge.

In order to give the trees a symetrical shape and to reduce their height and width, I would like to prune them. Ideally this would be into a small round or oval shape, but I am unsure how and when to do this. Also, the trees rarely flower and produce berries. They did so last year but not this. Could it be the effect of the trees behind them?

Thank you for reading this far and I hope someone has some suggestions for me.

I pruned mine in Nov/Dec last year and it seemed fine.  My tree hasn't produced any flowers or berries this year but is only 3 yrs old so that could be why.  Hopefully someone with a more mature tree will come along with some advice.  They are such lovely trees but I'll admit mine has looked a bit sorry for itself the latter end of the season with leaves coming off early - maybe didn't like the weather!

Hi, my tree is is about 12 yrs old too.In pruning, I have only removed lower branches in late winter and they have healed well. My tree does not regularly flower and produce fruit. Two years ago it produced 1 bunch of flowers and no fruit. Last year it produced both and was covered in both flowers and fruit all over - the first time this has happened.This year it produced neither! I can see no rhyme or reason  for the production or otherwise of flowers/fruit and usually look at other white beams locally to see how they are performing.

Thanks for the responses. I think I will bit the bullet and prune by about a third.

Daintiness, I wonder whether it was something to do with the weather conditions last year that made our trees flower so well.
