Post-harvest vineyard care

Harvest has finished in most Australian Wine regions and our thoughts turn to managing our vines through until dormancy. Many areas have had a very challenging, hot and dry vintage, including record high temperatures. Little rain has fallen during the season and none appears to be on the horizon. The post-harvest period is a great opportunity to give your vines a little tender loving care; if you have some water available post-harvest irrigation; or even better fertigation, will help them maintain a healthy canopy and build up reserves before they go into dormancy.

However, nutrition remains an important part of managing a vineyard since it impacts on vine growth, crop yield, berry composition and ultimately, must and wine quality. A ‘one program fits all’ approach is not achievable since nutritional requirements must tailor to a range of variables including grape variety, rootstock, vine age, soil type and properties, water and irrigation supply, production and wine quality expectations, and management history … Continue reading
