Underground cement barrier

I have a decent idea on how to make a "barrier" persay. Leave comments and ideas because i am so going to try this. I plan on digging a 2 and a half feet rectangle that is 6 inches wide and this is somply the perimeter of the barrier. So inside this rectangular trench is dirt. Then when the cement dries, Would it dry even??, dig out the cemter, make the cement bottom, discard dirt. Then fil this with good storebought soil, or make it a secret compost bin thtll always have fresh compost soil. And i plan ion doing this in the woods, would it even dry??? ideas please....

huh? use grammar, complete sentences, proper punctuation, and be more detailed. i'm not trying to be a bitch, but i literally have no clue what you're asking...

sometimes the fastest way between point A and B isn't always the best way...

that sounds kind of small, it would probably need drainage, why wouldn't you just dig a hole and fill it with good soil anyway, i don't see the need of the barrier, its just going to give your plants less root space
