Heading Cuts| Pruning to Nodes| Crown Restoration

Ekka

Occasionally to prune to target (collars, unions etc) would leave very little of the trees biomass, an alternative is heading cuts preferably back to nodes.

Guy Meilleur aka Treeseer has been an advocate of this practice. Often the only alternative to this for trees would be removal.

A PDF 1.68mb sitting at this URL to get the ball rolling.

The Australian Standards AS4373 2007 has made allowance for the similar practice to rejuvenate trees in similar predicaments.



There's follow up work to be done with selecting stronger well positioned shoots to take the role of the new leader.

I'm sure Guy will back this with some supportive documents and evidence.

Unions and forks yes but not collars really. The thickenings at the nodes on branches where laterals were shed are also collars. After all, they still have all the elements of a branch protection zone.

It makes a lot of sense, especially when removal is the alternative.

Also, with many trees, all the heading cuts don't need to occur within the same year.
