best soil to use
I just built a large box container for gardening. It's 10' long, 3'wide and 2.5' deep. Should I layer the box with potting soil then compost or dirt? And what is best to retain moisture?

I like to use a combination of 60 % topsoil, 30 % compost and 10% soilless growing mix (commercial potting soil).
