This process, known as “hilling,” encourages the development of more potatoes. With proper preparation, your grow bag can provide an ideal environment for a successful potato harvest.

C. Chitting Potatoes

Chitting potatoes is a process of sprouting the seed potatoes before planting them. This can be done by placing the seed potatoes in a cool, light place for a few weeks before planting. The sprouts that develop will give the potatoes a head start once they are planted in the soil, leading to faster and more uniform growth. This can result in a higher yield at harvest time.

Planting Potatoes in Grow Bags

A. Planting Process

When planting potatoes in grow bags, it’s important to choose a location with full sun and good drainage. Fill the grow bag with a few inches of soil and place the chitted seed potatoes on top, spacing them out evenly. Cover the potatoes with more soil, leaving a few inches of space at the top of the bag for watering. As the potatoes grow, continue to add more soil to cover the stems, leaving a small amount of the plant exposed. This will encourage more tubers to form along the stem, increasing your harvest. Water the potatoes regularly, and once they start to flower, you can begin to harvest small, new potatoes or wait until the plants die back for a larger harvest. With proper care and attention, your grow bag can provide an excellent growing environment for a successful potato harvest.

B. Watering and Fertilizing

To ensure a successful potato harvest in your grow bag, it’s important to water and fertilize your plants regularly.
