Research Report: Low input weed management of wild blueberries, 2014 to 2016

Download Resource


Effective weed management in wild blueberry can be challenging for the organic and low-input grower. Semi-annual burning and mowing will control woody species, but will not control grasses such as little bluestem, bunchberry, bracken fern, and many other important weeds. We explored the use of sulfur as a weed control method for little bluetemm which has become the primary weed of concern in many lowbush blueberry fields. In theory, applying sulfur to lower pH provides the blueberry, which thrives in acidic soils, an advantage over grasses, which thrive in neutral pH soils. 

Our objective was to determine whether sulfur could help control little bluestem in two organic or low-input sites. Access the full report for more details.
