The best defense against weeds and unwanted pests is to maintain a healthy and thick lawn. When lawns are healthy they will help to choke out weeds. Another benefit of a healthy lawn is better disease resistance and drought tolerance. The fertilizers that we use have both macronutrients and micronutrients. They are well balanced to promote not only plant health but also soil health. What goes on under the grass plant is just as if not more important than the grass you can see. We also use combination fertilizers for both pre emergent weed control and grub prevention. Preventing weeds and grubs is a better route to take than trying to correct them after they have developed.
