Using a weed and feed product in the fall will help control broadleaf weeds and keep your lawn green throughout the season. The success of using the product depends on taking the correct steps to ensure the proper absorption of the herbicide and fertilizer. The weed killer in the product works to kill active young weeds. The fertilizer is often a type of quick release nitrogen that will green up the lawn and create an environment in the soil for healthy growth of leaves. Apply weed and feed only once a year; feed your lawn more often.
Watch weather reports and plan to spread your weed and feed when there will be no rain for a few days afterward. You should also watch for hot spells as you will not be able to water for a few days. Mow the lawn two to three days before the planned time.
Wet the lawn just prior to spreading the weed and feed. This will help hydrate the weeds so the weed killer will be more readily absorbed. It will also help the weed killer to stick to the leaves.
Place the weed and feed into a dry, clean spreader. Follow the manufacturer's recommendations on how much to use per square foot of lawn.
Set the application rate on the spreader according to the manufacturer's directions. Do this by turning the application rate dial to the correct number.
Spread over the lawn in a uniform manner. If your spreader does not have an edge guard, be careful not to allow the weed and feed to cast into your flowers, shrubs or sidewalks. Weed killers can kill flowers, damage shrubs and leave hard-to -remove stains on your sidewalks and driveways.
Do not water the lawn for at least two days after application or you may wash off the weed killer before it does its job.
Do not aerate for at least two weeks or plant any new grass seed for at least 4 weeks.
