Yellow nutsedge found a good home in warmer areas of California and purple nutsedge is sometimes present as well. In bare-ground soils the depth of roots and tubers varies from few inches to two feet, but we wanted to know how does yellow nutsedge grow and produce tubers in beds covered with plastic mulch. Plasticulture in increasingly common and almost all strawberries, fresh market peppers, tomatoes and some other crops on the coast are grown on mulched beds. In previous studies we have identified barriers that are dense enough to resist sharp tips of nutsedge shoots and are either water resistant or protected from wetness with low density mulch. The barriers were more economical than hand-weeding, gave nearly 100% control of nutsedge...
