I am a novice gardener. We have three Acers. About 18 months ago, we had two gardeners come to tidy our garden. They trimmed the ends of the acers, consequently they have sprung a lot of side shoots, which have completely spoilt the shape of the tree. We asked the advice from specialist shrub growers, who advised going back to the main branch and cutting out the off shoots. I have done some in January, but is this the correct thing to do? How can we get our lovely acers back to their former glory. Is it just a matter of time?
Thank you for any help you can give
