It is very popular and effective for weed control to use a weed killer in park grassland. But we may not use a weed killer too much, because of the misgiving of influence to the health of children' sick person and other park users. Then mowing is expected for weed control as an auxiliary method.<BR>Weed vegetation in the Zoysia grassland was surveyed under the different mowing condition. Zoysia grass grew rapidly when mown every four weeks, but the weed covered area was increasing too. Then the weed vegetation was dominant when mowning height was 5.5cm. When mown every one week, grass covered area was slightly increased.<BR>Creeping type weeds were decreasing under low level (2.5cm height) mowing height. But the mowing frequency did not influence to the spector of seed life form. Rossete type weeds made appearance constantly when mown every week at 2.5cm height. But in any other mowing condition, rossete type weeds made appearance more increasingly.
