We've just completed a new information sheet on pruning, which is designed to give you an introduction to the why, when and how, and give you the confidence to get out there and have a go.  Obviously it's a big subject so it's a good idea to do further research and consider attending a training course (such as the one being run by orchard link on the 21st) if you're still unsure. 

The info sheet can be viewed as a pdf from the toolkits and downloads section of our website but do let us know if you would like us to send you a hard copy.
