To have a landscaped backyard or front lawn, keep the weeds at bay. There are several ways to eliminate weeds, including hand picking, but they always seem to come back. Weed-killing herbicides come in two forms: selective and non-selective. Selective herbicides target specific weeds. Non-selective herbicides kill all vegetation and should be used with caution around plants not intended for eradication.
A selective herbicide, fluazifop-p-butyl targets Bermudagrass and can be used on lawns of tall fescue or zoysia grass. This herbicide is sprayed over the top of the lawn two times during the growing season. Apply the first treatment in the early spring when the Bermudagrass is just coming out of dormancy. The second treatment is applied in the fall when the Bermudagrass is preparing for dormancy. Herbicides with fluazifop-p-butyl are not recommended for use during hot, summer months. It is not safe to spray on plants that are going to be consumed within one year before harvest.
Glyphosate is a non-selective herbicide for weeds and grasses. Because a glyphosate herbicide kills everything it touches, it is best to use it on driveways, sidewalks and in areas where vegetation is not wanted. It can be used in flowerbeds, but care must be taken to protect and shield ornamentals from unintended treatment. Glyphosate herbicides kills annual and perennial weeds and plants. A glyphosate herbicide (depending on the brand name) can be applied 1-1/2 hours before rains without losing potency, but for best results apply it at least 24 hours prior to rain.
Top Organic Herbicide
There are two products that could be used on weeds that are safe for the environment: vinegar and rock salt. Both products kill everything they touch but are effective for use in driveways, on sidewalks and on patios. Spray the unwanted foliage with vinegar until the plant is soaked. When using rock salt, spread the rock salt around the base of the plant. Sprinkle the leaves of the plant with ground rock salt. These products take longer to work than commercial products.
