Growing Eucalypt posts for vineyards
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.
