how do I get rid of crab grass? yuk?

I was working in my flower garden that is way beyond what I should have. Crab grass galore and I hoe and hoe and hoe , get done and look at it in a proud manner, and that CRAB GRASS is again sticking up though all my plants. How in the heck do I get rid of it. No fishing today because the wind is prob 30 miles an hour and the waves will be soooo big. Should have gone this morning when it was calm. Maybe tomorrow. Everything is green and full from the rain last night and it is another beautiful day in northern MI. www.nappernoo.com
