The widely tested mulches, such as pine bark, rice hull, Douglas fir bark, coconut coir, newspaper pellets, and waste paper (Pellett and Heleba, 1995;Penny and Neal, 2003;Amoroso et al, 2009;Mathers and Case, 2010;Chen et al, 2013;Marble, 2015;Bartley et al, 2017;Burrows, 2017;Masilamany et al, 2017;Marble et al, 2019;Massa et al, 2019). Adding mulches (2.54-7.62 cm) can reach satisfactory weed control results depending on mulch types and weed species (Richardson et al, 2008;Cochran et al, 2009;Altland et al, 2016;Massa et al, 2019;Särkkä and Tahvonen, 2020).…”
