Add Soil and Vegetables
Vegetables need soil that's roughly half dirt and half compost. The county dump is a great source of materials that a lot of people don't know about. They often have piles of compost that's free if you pick it up. Mix equal parts of dirt and compost to make the garden soil. If you have clay soil, you may need more compost than dirt to make it lighter and more aerated; if, on the other hand, you have sandy ground, you may need to add more soil to keep water from draining too quickly through the bed.
