care for a large lawn

I live in the country but I like the looks of a city lawn. I mow a little over 3 acres so it can get expensive in a hurry. I would like to know what I can do to enhance the looks and help control weeds and dandelions. I am looking for answers to cover building up lawn mainly. I don't know if I should add lime, fertilizer, potash, or nitrogen. I have a pull type spreader and a pull type sprayer. My other problem is I have several flower beds so I have to watch out for them. I have used weed- n-feed and I can do that again but I have read lately that is not a good idea. If you can give me any advise it will be greatly appreciated. If you need any other information let me know.

Thanks, Cleo

Clover is often associated with low soil fertility. Clover is a perennial weed with seeds lasting in the soil for many years and has an extensive root system. Clover is best managed with a combination of 2,4-D, MCPP and Dicamba. This combo is sold under a variety of trade names. Clover is not suseptible to 2,4D alone as are most of the other broadleaved weeds. If you want to treat this spring, wait until the young growth on your flowers has matured or wait until fall.

Fertilization should be done based on a soil test so that you can apply what is missing without putting down nutirents that are not needed, saving the enviornment and money. Turf responds to nitrogen the best of the three main nutients found in commercial fertilizers. If you want to apply, a formula similar to a 10-6-4 (NPK) will be fine. If you are only going to apply once a year, the fall is the preferred time. The soil test will also tell you if you need to add material to change the pH. Most of our soils do not need lime.
