Weed mat determined to be more cost effective than hand weeding
Researchers evaluated three weed management practices using two trailing blackberry cultivars in western Oregon. Weed mat was determined to be the treatment best suited to organic production of blackberries. The initial cost of the weed mat was considerably less than the cost of hand weeding during the first 3 years after planting. The yield benefit of weed mat provided enough profit to warrant its use after only one season of fruit production.
