What is weed and feed, and how does it work?
Weed and feed is a type of lawn fertilizer that also contains herbicides to kill weeds. It typically comes in the form of a granular or liquid product that is applied to the lawn using a spreader or sprayer. The fertilizer component of weed and feed provides essential nutrients to the grass, such as nitrogen, phosphorus, and potassium, which promote healthy growth and development. The herbicide component, on the other hand, targets broadleaf weeds like dandelions, clover, and plantain, killing them or preventing them from germinating.
The effectiveness of weed and feed depends on various factors, including the type of grass, the severity of the weed infestation, and the timing of application. In general, weed and feed works best on lawns with moderate weed pressure and when applied during the active growing season. However, it may not be suitable for lawns with severe weed infestations or those with certain types of grass, such as newly seeded or sodded lawns. It’s essential to read the product label carefully and follow the instructions for application to ensure optimal results and minimize potential risks to the lawn and the environment.
When should I avoid using weed and feed on my lawn?
There are several situations where it’s best to avoid using weed and feed on your lawn.
