Do you think it's too early to fertilize in Chicago ?

My grass isn't green yet (of course) But some flowers are begining to show.

You should be applying a pre-emergent selective herbicide now. Scotts has some good products out there that include fertilizer. If you want to be more earth friendly, Milorganite is very good, but doesn't have the weed control. It's not too early because the grass is still growing, you just can't see it. I don't know if you'll get snow again, but spreading fertilizer on a light skiff of snow is a good method of applying it. It looks nasty, but the snow helps to disolve the granules and the nutrients seep into the soil more evenly.
Reply:No, it's actually the perfect time to apply a first application of lawn fertilizer. Also, if you have crabgrass, you should plan on applying fertilizer and crabgrass preventer around May 1. Plan on a total of four applications of fertilizer throughout the growing season, but don't fertilize at all during the hot months.
Reply:Too early for weed preventer, but fertilizer can go on at anytime.
