"This is the best time of year to obsess on your lawn. If you want to do it organically, here are some ideas from the experts:
Buy a soil-test kit to see what shape you're in. They cost about $10 at state university cooperative extension offices and garden centers, and the results will help you determine which organic fertilizer you need.
If your soil's like cement, aerate the lawn to loosen it before you apply compost or organic fertilizers made from things like alfalfa and corn gluten. Home Depot rents aerators for $88 a day, $62 for four hours.
Brew a nutrient-packed "compost tea" to feed the lawn. Great stuff. Find how-to details at www.safelawns.org."
