Amend your garden soil with 2 inches of compost and till it into the top 6 inches of the soil.
Plant your beet seeds 1 inch in the ground and lightly cover with topsoil. Space your rows 14 inches apart.
Water the rows and keep the ground moist until the beet greens emerge. After that you can reduce your watering to once a day or whenever the top of the soil dries out.
Thin your plants to 2 inches apart as they emerge so that you'll have large beets when you harvest.
Weed the rows as you see weeds emerge to prevent nutrient loss in the soil.
Harvest your beets once the greens reach 1 1/2 feet high.
