Shelby--
Thanks...I know...it's sad. Nobody wants to help the weatherman. I saw a commerical about a Bayer product that claims to kill all weeds (including crab grass...which is weird because I always heard you had to kill it before it grew) so I am going to buy some today before work.

"Normal Lawn Grass" is generally very fine and the individual plants will be closely "knit" and nearly equally spaced from each other.

Crabgrass, on the other hand, does not look like "Lawn Grass" but instead has "sea green" "broad" leaves which grow along stems which tend to "hug" the ground whereas "Normal Lawn Grass" tends to grow vertically.

Because Crabgrass has broad leaves and likes to spread horizontally it has the tendency to "smother" the desired grass as it grows.

Evev though Crabgrass is in the same "family" as "Normal Lawn Grass" there is a specific herbicide that you could spray on your entire lawn that will only kill the Crabgrass. I don't know which one it is though.

I hope that you are able to eradicate your yard of the Crabgrass!!

From what I remember, some herbicides need to be applied when it is much warmer than it was on Friday. When it is cool like it was Friday the active ingredients in the chemicals tend to not "do their job" and so it is as if you hadn't done anything at all. I noticed the ground was still very wet on Friday.

Plants are most likely to die when they are very "stressed". Did the product label say anything about not apllying it below say like 75*F? As I recall Friday was a bit windy as well... a bad thing when spraying! The warmer it is the more vegetation "transpires", the cooler it is the more their transpiration slows down.

Additionally, 24 hours seems to be "rather quick" to me. I would guess that by Tuesday morning you should be able to see some wilting and/or browning of the Crabgrass leaves if the product is working properly.

try using some scott's grabgrass and spurge killer. if i remember right, it works pretty well.
