Although many consider dandelions a weed, they are not a weed by ordinance, and do not constitute a violation, unless taller than 8”. City ordinance prohibits state listed noxious weeds, and grass and rank vegetation in excess of 8” (inches) in height.
Noxious weeds in Minnesota have been found to be injurious to public health, the environment, public roads, crops, livestock, or other property. The purpose of the Minnesota Noxious Weed Law is to protect residents of the state from the injurious effects of noxious weeds. There are twenty-six plant species regulated as noxious weeds in Minnesota. Twenty-one plants are listed as prohibited noxious weeds which consist of two regulatory lists- eleven plants listed on the “prohibited eradicate list” and ten on the “prohibited control list”. Prohibited noxious weeds must be eradicated or controlled in accordance with the Minnesota Noxious Weed Law. Four species; common buckthorn, glossy buckthorn, multiflora rose, and black swallowwort are listed as restricted noxious weeds and are prohibited from importation, sale, and transportation in Minnesota. One species, poison ivy, is listed as a specially regulated plant that can be enforced under specific conditions (Source: MN Department of Agriculture).
In Apple Valley, long grass and vegetation in excess of 8” (inches) in height in lawn areas, and not specifically part of a garden or natural area, is also considered a violation and must be trimmed upon notice.
