First, we need a little more info. What kind of soil do you have, i.e. sandy, loam, clay, silt? Is the area shaded, partially shaded, full sun? What kind of veggies are you trying to grow?
I have a different types of soil on my property. It is primarily sand, but has been built up with rotted cow manure, top-soil, and plant material. The back garden supports most anything I want to grow in it. It is slightly acidic soil and so does well with everything from string beans to zuchini. Peas grow phenominally as do strawberries, raspberries, and blueberries. Cor owuld grow well if the squirrels 9and no I'm not talking about my wife here
) would leave it alone.
My side yard is mostly rich loam. Kiwi plants are growing great, as do herbs and flowers. But my blueberries want better drainage and a more acidic soil. They are doing ok, but could be better.
My front yard is mostly pond sand on top, but is pure sand underneath. My maple trees and lilac bush are doing extremely well on that soil, but not so much with the grass. Dandelions love it though. Again, the soil is slightly acidic.
Let us know what you have and someone here will be able to help you.
