发明名称 Prevention against grass ingrowth in all types of tree and shrub
摘要 Disc for conifers for preventing grass ingrowth. Tree plantations (e.g. Christmas trees) require continuous care in order to prevent grass ingrowth. This is associated with running costs and often with environmentally harmful spray agents for restricting the grass ingrowth. The disc according to the invention prevents this. The same consists of plastic, has a diameter of approximately 300 to 600 mm depending on tree size and is pushed over the trunk and nailed securely to the ground. In the region of the disc, no further grass ingrowth is thus possible. The disc saves a lot of work and environmentally harmful spray agents.
