Thanks Neil. Don’t really understand that but stranger things have happened; don’t plants root outwards in an omnidirectional fashion?
Very large spacings seem to be favoured by professionals, and these plants can live up to twenty years plus, hence allowing for future growth/ expansion of the crowns. I’m not sure if lifting established crowns for replanting would be a false economy, or if starting with new, one year old crowns is a better bet? Thoughts?
