After you have received the results of your soil test and begin to correct any fertility imbalances (recommendations will be listed from the test lab along with contact information to answer any questions you may have)the best defense against weeds and crabgrass is to continually over seed your lawn. The thicker the turf, the less likelihood of weeds to take control. As with any living organism, aging causes decline. Continual over seeding keeps your lawn young and vigorous and therefore able to compete with any of the unsightly weeds that maybe trying to establish themselves in your lawn. This is the perfect time of year to overseed and get a jump on those unwanted weeds and crabgrass.
