In an effort to curb garlic mustard and spotted knapweed on residential properties, Summit Park neighbors are able to sign up to get weeds treated for free.
April 4, 2019
Dear Summit County Land Owner;
The Summit County Cooperative Weed Management Area (Summit County CWM) in cooperation with the Summit County and Salt Lake Weed Control Departments, Park City, and Snyderville Basin Special Recreation District, have been awarded a competitive grant from the Utah State Department of Agriculture and Food (UDAF) to map and treat two state listed noxious weeds, garlic mustard and spotted knapweed.
Please help us contain the spread of these high priority invasive plants by participating in this county wide management effort. If you have garlic mustard and/or spotted knapweed and would like to have your property treated free of charge by licensed contractors, you must agree to the following:
• Learn how to identify garlic mustard and spotted knapweed both as a rosette and when in flower (see attached fact sheet);
• NEW THIS YEAR: Pull any flowering garlic mustard plants prior to free herbicide treatment of rosettes (unless prearranged agreements with the Summit County CWMA are in place).
• Monitor, pull, and bag or treat with herbicide any missed or newly germinated plants 2-3 weeks after treatment and throughout the growing season (May to November). Infested areas must be monitored for a period of 10 years to deplete the seed source; o Please note: If garlic mustard and/or spotted knapweed are growing in ornamental or landscaped areas, you must control these yourself as the contractor will not treat these areas.
• Educate your community about garlic mustard and spotted knapweed control;
• Agree to allow a contractor to enter your property to treat garlic mustard and spotted knapweed infestations using a selective herbicide free of charge;
• Sign and submit a consent form for each of your lots by April 30, 2019.
Your personal information will not be shared with anyone. Follow this link: http://summitcounty.org/155/Weed-Division
**Please note** that funding is limited and priority for treatment will be given first to open space and public properties and private properties adjacent or connected to open space and public properties by recreational or wild game trails. Once these properties are treated, treatment will be provided on a first come, first served basis. Please also note, you are receiving this letter because your area has been designated as a high priority for garlic mustard and spotted knapweed control. Timing of treatment will vary between the two weed species, with weather and plant growth stages. Treatment typically begins in May and ends in October (see timeline diagram).
A professional licensed weed contractor will be in your neighborhood this season to both map and treat garlic mustard and spotted knapweed with the appropriate herbicide. If you wish to be notified with a more specific treatment time frame, please contact Sara Jo Dickens at 303-549-2089.
Together, we can slow the spread of this invasive weed! Thank you in advance for support.
