We lived in MS and mom and dad came for a visit. The two fiest dogs kept all critters out of the garden. We never lost a thing due to critters.
We had a man come with a mule and plow it up for us. And we did plant with space between each plant, as you can see in the black and white photo.
We did the same with the raised beds, that is just one tomato plant in the other photo. We have found that using the raised beds, our yield was greatly increased. The plant grew much larger, and more productive.
