Grow­ing Eu­ca­lypt posts for vine­yards

New Zealand Logger - - Forest Growers Research -

WOOD­LOT AND SMALL FOR­EST OWN­ERS COULD earn big bucks from grow­ing Eu­ca­lyp­tus trees to be used as posts for stak­ing grapevines in vine­yards.

Marl­bor­ough-based re­searcher, Paul Millen, told the For­est Grow­ers Re­search con­fer­ence in Christchurch there is a need for an al­ter­na­tive to us­ing treated Ra­di­ata Pine posts, which break eas­ily dur­ing me­chan­i­cal har­vest­ing and also may not be al­lowed in vine­yards be­cause of the CCA chem­i­cals.

Mr Millen says hard­wood posts are used ex­ten­sively and suc­cess­fully in Aus­tralia and they also per­form well in New Zealand con­di­tions. He says vine­yards use 600 posts per hectare and in Marl­bor­ough alone there are 25,00 hectares un­der vines.

Re­search is cur­rently cen­tred on which Eu­ca­lyp­tus species would make the best posts.
