I'm planning a garden that I hope will provide most of the vegetables for our family of 6. How big of a garden should we make? The spot is now covered in weeds. Should we plow these under now, and then cover the garden with plastic until Spring? We live in an area where it never snows, and rarely freezes. Our soil is very sandy. I have one trash can of finished compost, and another one that might be finished by planting time. Should I plan on buying more, or would that be enough? We also have many deer and rabbit. Would a welded wire fence with electric on the top and bottom be the best for discouraging them? Thanks for your help.
