I have not cordoned my gooseberries yet but last year I moved them and at that time I cut off all the lower branches, all the branches in the middle, and left them with just the tallest branches around the side. What a difference it made to picking ! I could get my arms under the branches to slide off the fruits and get into the middle through the top. First time I haven't been ripped to shreds. And I got quite a good crop despite the rather radical pruning! I have planted two stakes around them though so maybe in autumn I will start to tie them in.
