Best soil for veggie garden?

I would say nature's best 38$ a yard, expensive but well worth it free of weeds.

Thank you. How much is sliver free bark o mulch for a square yard?

What you want is Hemlock bark mulch which is a dark color and finer grind than for. As for amount, you need the number of square feet to be covered and how many inches deep. With that info, the employees can tell you how much you will need. A yard is 27 cubic feet, not square feet.
