My lawn is not doing well -- I have a lot of crab grass and weeds. My mowing man said I should fertilize in July. I was just wondering if that is a good time and also should weed control be included at that time? My lawn will need to be re-seeded this fall as well. I would like some help on the best way to do that -- my lawn is sloping -- goes down to my house. Thanks so much! I will try to get some pictures to you.
