Each of us dream of the perfect lawn. The following offers some help to maintain that lush green lawn free of weeds. The most common weeds seen infesting lawns in Saskatchewan are found below. Fescues are the best for shady areas, whereas turf-type perennial ryegrass varieties, which require full sun, establish themselves quickly in newly seeded areas and will crowd out germinating weeds.
Kentucky bluegrass establishes more slowly, but once it is established it is very competitive.
The 2,4-D spray works best in the spring or in September when broadleaf weeds are actively growing. This treatment will generally thin Dutch clover in the lawn. A large number of broadleaf weeds resistant to 2,4-D can be controlled by mecoprop, dichlorprop, and dicamba. A thorough wetting of the leaves with any type of chemical spray is required for effective control. Be careful when using dicamba near shrubs, etc.
