Ours is about 50' x 20'. I divide it is thirds, moving everything one section East every year, and back West the third. This year it is row crops, corn, beans, parsnips, etc. then tomatoes, then squash, no zucchinis, but summer crooked necks and butternuts. We have plenty of rhubarb, and wild black raspberries behind the garden. I dig down and cut the walnut tree roots the years the tomatoes are at the end with the neighbor's tree.
We had our first squash and beans last night. Plenty of lettuce, radishes, and spinach. The corn is in tassel and we have green tomatoes. We plant Superstake tomatoes. They are an almost smooth hybrid of the old Beefsteak. They actually get ripe, unlike may of the modern varieties, crimson red, soft, and sweet.
Parsnips need to stay in the ground into the winter. Mostly we dig them in the spring.
We have let some of the dogs in the garden some of the time, but mostly keep them out.
It was the parsnips we served him that finally drew a comment from our son in law. He didn't grow up on squash, yellow beans, and parsnips.
