Weed and feed lawn fertilizer is plentiful and in most cases when applied properly will contribute positively to a lush lawn. They contain nitrogen, phosphate and potash which are essential for lawn growth together with a herbicide. Again, it is important to select a product that is designed for either warm or cool season grasses.
Typically the Spring fertilization period is best for applying these products. The first weed and feed product to be applied to the lawn contains an herbicide known as a preemergent herbicide, that is it prevents the weeds from successfully germinating and thus prohibits weeds from starting. These products are generally successful in preventing early weeds, but as summer approaches weeds will emerge and become more noticeable.
During the late Spring and early-Summer another weed and feed application may be necessary which includes a herbicide designed to kill weeds that have successfully emerged.
Weed and feed products will generally kill a wide range of different types of weeds, however they will generally not prevent or kill crabgrass – the most pesky of all weeds. Consumers should examine lawn fertilization products to insure that a crabgrass pre-emergent is among the herbicides in the package or purchase a separate crabgrass preventer if the desire is to eliminate this weed. Following recommended procedures for the application of a crabgrass pre-emergent will generally prevent crabgrass during the entire growing season. Typically nature gives us a clue as to when to apply the first application.
When one sees daffodils, forsythia, and dogwoods begin to bloom it is time to apple the pre-emergent. The early time frame for application is signaled by the blooming of Forsythia and daffodils. The blooming of Dogwood trees represents the last opportunity for application.
Warm season grasses essentially start growing from the roots up as the warmer months approach. It is important to read product labels carefully to insure that any weed killers or crabgrass preventer’s will not stunt the growth of any warm season grasses. One should be particularly careful when applying these products to St Augustine grass.
In summary weed and feed products make the fertilizer application process much simpler and easier. One should follow product labeling procedures and if applied in the right amount at the right time the homeowner will be rewarded with a beautiful lush lawn.
