My wife is really messy, how can I get her to be more organized?

I clean up all the time and try to keep things as organized as possible but my wife is a pack rat and when shes in a hurry she just leaves stuff all over the floor. For example jackets, shirts, shoes, makeup and etc, shes a mess. Ive tried talking with her about this and she does the same things over and over, and believe me its getting very tiresome when you also have a 2yr old boy to cleanup after. I'am so pissed off right now, I dont know what else to do, I cant drop the ball or she wont clean, yelling at her hasnt done nothing, how do I wake her up to her habits?
