Hi Tom,

This is a great article. I found it about a year ago and have been employing
the zigzag approach to some of my trees. Then I misplaced my copy and
couldn't remember where I'd found it on the internet. Glad you helped me
find it again.

Cheers, Bizmark.

"A preferable leader-management technique is called "weak leader renewal"
(Fig. 2A). This management technique removes the vigorous upright leader
and replaces it with a weaker branch to devigorate the leader, maximize
branching, and encourage early fruit production. Weak leader renewal
involves pruning the central leader during the dormant season or after bud
break, if excessive vigor is a problem, just above the highest usable
lateral. The lateral is then pulled up and headed at 12 inches and tied to
the tree stake as the new leader. Weak leader renewal can also be used to
maintain the leader in ensuing years. Weak leader renewal can also be used
with feathered trees that have lower branches and no higher branches. The
leader is removed above the highest usable lateral and then that lateral
branch is pulled up to replace the leader."
