Johnsongrass, Shattercane, Palmer Amaranth, Tall Waterhemp and Thistles have been declared prohibited noxious weeds in Maryland.  These weeds must be controlled by anyone owning or managing land within the State.  Seeds from these noxious weeds are transported by wind, water and man once the plants have matured.  These weeds threaten the productive land of farmers and cause unsightly and unwanted problems in lawns and gardens of homeowners.

​General control practices include mowing, cultivation and/or treatment with approved herbicide.

Spray Assistance

Should you or someone you know have noxious weeds and need assistance controlling them, Baltimore County's Noxious Weed Control Program provides spray services on a fee for service basis.


If noxious weeds are spotted on your property by Baltimore County's weed control coordinator, you will be cited and sent an advisory notice informing you that by law you are required to control them.  Failure to control noxious weeds within the time allotted will result in a possible fine.
