Your soil supplies some of the nutrients that turf/grass needs. Most soils are not able to provide all of them during the entire growing season. A healthy and actively-growing lawn uses a great deal of energy. Fertilizer helps your lawn stay healthy by:
1)Promoting new leaf and root growth.
2)Aiding in the recovery from foot traffic and pest damage.
3)Reducing and controlling weeds.
4)Replacing nutrients lost to leaching, volatilization and grass clipping removal.
Weed and Feed is a common term which refers to fertilizer that contains weed killer for broadleaf weeds such as dandelions.
Pre-emergents, such as those commonly used to prevent crabgrass, are weed killers which must be applied before the weeds germinate. They are ineffective if the weeds are already actively growing. Pre-emergent weed killers are often mixed with fertilizer and are designed to be spread in early spring. Crabgrass normally germinates when the ground temperature reaches 60° F – the ground temperature at which dogwood trees start to bud andforsythias begin blooming.
Post-emergent The weed killer in these types of fertilizers are contact killers, and are effective only if the weeds are already actively growing. They will not kill weeds which have not yet germinated.
