Growing potatoes in the home garden provides a supply of delicate new potatoes sometimes referred to as "baby potatoes." These immature potatoes are sweet and firm, making them an ideal accompaniment to any meat dish or in fresh potato salad. Growing potatoes requires garden space as these robust plants produce tubers under the ground. When space is limited, potatoes can be grown in straw, large bins or buckets or directly in a bag filled with soil.
Fold over the top half of a heavy-duty garbage bag and fill with a mixture of one part compost to one part garden soil. Potting soil can be used in place of garden soil but add peat moss to loosen soil and provide aeration.
Puncture several pencil-size holes in the bottom of the bag. Space holes 6 inches apart in all directions. Holes allow the soil to drain properly.
Plant a certified potato seed in the bag. Place one potato per bag to a depth of 4 inches. Water to moisten soil and watch for seedlings to emerge in 14 to 28 days depending on the cultivar and weather conditions.
