Two levels of mowing were applied to the ground cover in two apple orchards (one old and one new), and the species composition and seasonal dynamics of weeds were investigated. Trifolium repens was the dominant species in both mowing treatments. Erigeron philadelphicus, Mazus miquelii and Taraxacum officinale were also observed frequently. When weeds were mowed at a relatively high level, T. repens appeared from April through October in the old orchard, and from mid-June through early October in the new orchard. In contrast, the dominant species changed two and three times when weeds were mowed close to the ground in the old and new orchards, respectively.
