The northwest (Oregon and Washington) is the largest growing region for blueberry (Vaccinium corymbosum L.) in the USA, accounting for 35% of the total harvested area and 62% of total production in 2020. Long-term research on organic systems for blueberry has been conducted in western Oregon since 2006. Outcomes from trials have had significant impact on production leading to over 20% of the total blueberry area in Oregon and Washington certified organic, and production of 77 million lb (65% of USA organic production). In this presentation the key soil and mulch requirements for blueberry will be highlighted, including use of pre-plant amendments. Important results from research trials will be presented including a 10-year study (2006–2016) comparing planting method, fertilizer source and rate, and mulch in ‘Duke’ and ‘Liberty’.
