 Hello, please can anybody with experience advice me whether to prune a hazelnut Bush I have in the garden? Its an established Bush, very tall but certainly neglected for at least 10 years. It gives a modest crop which I’d like to improve.

Many thanks Louise

Welcome to the site 

The article on growing hazelnuts on this forum's main site doesn't specifically mention pruning hazelnuts.

However, the RHS says you can prune an established plant in summer (for heavier cropping) or in winter (to remedy congested growth), and there are instructions on how to do so there:

Thanks for your guidance and great name, my kids miss Yorkies so much! Relocated to Bulgaria so have to get decent chocolate shipped. 

Best wishes Louise
