The one year I tried this it didn't work because the very night after I scattered the seeds in a small maybe 5x5 area of our backyard, it rained buckets and buckets and washed all the damned seeds into the next county I think.  I was so pissed off I just gave up for the year and worked only in the backyard greenhouse if I actually wanted to grow something.   The year before I tried the Chaos Garden I tried growing tomatoes in a big container in the front yard of our old house and the deer ate them right down to the soil.  I hope they poisoned themselves from the fertilizer granuales I had just placed around the base of the plants! 

After I move in with my son and his family (before we get moved to FL) I may try chaos gardening in their yard and see what happens.  They have cats, dogs, snakes, etc, but we'll give it a go anyway!

Ooops! Forgot the link!

It sounds simple enough but be sure to check the weather forecast in your area before doing this.
