For the past 5-6 years my lawn has been in bad shape. Last year we took out the entire lawn and planted it with seeds and still came out to like this. Spring started about a month ago and I do not know what to do. What type of fertilizer to get, how much lawn to cut, how much water I need to give , and lastly how can I get rid of these weeds, dandelions. crab grass, white clovers, chickweeds, and prickly lettuces, Please help me.
