Conifer Lost it's Central Leader
I have 3 Iseli Foxtail Blue Spruce trees, and one has lost it's central leader. It is only about 4 feet tall, while the others are about 7-9 feet tall. Can I train a side branch to be the new central leader? There is a long side branch at the top that could be used for this. What is the best method for accomplishing this. Thanks.
