How you decide to manage your lawn greatly depends on your lifestyle and your lawn goals. Decide what’s best for you and create a plan to have the lawn you desire. If your lawn is extremely stressed from the summer heat, it might not yet be the best time to start fertilizing, seeding, or killing weeds & crabgrass. Use your judgment, it may be better to leave it be for now and give your lawn time a little more time to recover before you start any projects.
