Crabgrass coming in/mow height
Hi, I am trying to go organic. My lawn was planted last year. I put down Organica brand fertilizer this past spring but I must have done something wrong as the crabgrass is really starting to come in strong. I was thinking about letting the lawn "go" (ie, not mow it). Will this be effective at crowding out the crabgrass or will it do more harm then good.
Also, I mow as high as my mower will go (about 4"). The lenght is about 5 days from seed at this height. I mow once a week (for the most part) and 1/2 the grass in the lawn is to seed. Is this OK or am I putting too much stress on the lawn. Should I change my mower height? I really do not have time to mow more often. Lawn appear OK otherwise.
