October is the month to do your fall lawn fertilizing and weed prevention. After that it is getting late to have maximum effect. If weeds are a problem every winter and spring, use a pre-emergent to prevent the weeds from sprouting. Amaze granules or Weed and Grass Stopper with Dimension are the best to use in October to prevent winter weeds and again in January to prevent spring weeds. An organic alternative is Corn Gluten. These chemicals only last one season, so be sure to re-apply in 3 months. If you have any other questions on Lawn care for the fall and winter, come see me at the Airline Store on Saturday October 10th from 10:00-11:00, for our fall Garden Talk.
