Sorry to go on about them, but mine look such a mess at the moment. I
am just having them trimmed (another bug bear, why do I have to pay
about £200 every 4 years for my neighbours trees to be trimmed? and I
am nackered from trying to cart all the branches down the garden in
this heat!)

I have noticed that after the tops are cut off, the side branches rise
upwards and form the growing point.

Can I put some kind of ring round these branches to stop them growing
up again?

Any other suggestions very welcome
Thanks
Janet
