Does your lawn really need a weed and feed application? Early spring may not be the best time to fertilize and treat weeds.
If you do use a weed and feed, make sure it does list the weeds that you have.
The links below will help you determine the best fertilizer choice for your lawn.
I would also encourage you to talk with your County Extension Office. The will give you the best schedule and usage of fertilizer/weed combination to use for your zone. They can give you specifics to your region, grass time and weather.
