Hi, I just bought a new home in April. I'm trying to figure out how to take care of the lawn. I noticed that when I bought the house, their was one type of grass that never really seemed to grow and was sometimes brown. Then there was another type of sporatic grass that would grow really tall, especially now in the summer. Now I have identified about 5-6 different types of grass/weed looking things growing in my lawn. What DIY steps can I do to take care of this?
