Start by collecting kitchen scraps that are suitable for composting. These include fruit and vegetable peels, coffee grounds, tea bags, eggshells, and non-greasy leftovers. Avoid adding meat, dairy, or oily items as they can attract pests. Cutting the kitchen wastes into small pieces, then filling them into self-watering systems.

Prepare Potting Soil

The ideal potting soil mix for growing potatoes in a bag includes soil, ash, rice husk, and coir. Begin with a base of high-quality garden soil. Add some ash to enhance the soil’s alkalinity, as potatoes prefer slightly acidic to neutral soil. Mix in rice husk to improve soil aeration and drainage, preventing waterlogged roots.

Finally, incorporate coir or ash to boost moisture retention and provide essential nutrients. Aim for a balanced blend that offers good drainage, aeration, and moisture retention. Once your custom potting mix is ready, fill your potato grow bags or containers and proceed with planting your seed potatoes or potato seedlings.

Chitting Potatoes

Before you plant your potatoes, it’s essential to let them sprout, this process is also called ‘chit’. All you have to do is allow the potatoes to grow some shoots, and this will result in a larger potato harvest.

Place the seed potatoes in egg cartons and put them in a well-lit and cool area that’s free from frost. Adequate light is important, so putting your potatoes on a windowsill on a porch or outside in a glass greenhouse is the perfect spot for letting them sprout.

Prepare Seed Potatoes

Using a clean knife, cut them into chunks, ensuring that each piece contains at least one eye or sprout. These sprouts are essential for new growth. Allow the cut pieces to air dry for a day or two; this helps to form a protective layer that prevents rotting.

Once dried, your seed potatoes are ready for planting. Ensure that each chunk is sizable enough to encourage robust potato plant development. Properly prepared seed potatoes will give your plants a strong start and lead to a successful harvest.

Make sure each seed potato chunk has at least one eye or sprout for growth. After positioning them, cover the seed potatoes with more soil, leaving about 2 inches of space at the top of the bag for growth. Water thoroughly to moisten the soil but avoid overwatering.

Cover with Soil

To ensure successful potato growth in your bag, cover the seed potatoes with a layer of soil. After placing the seed potato chunks evenly on top of the base soil, add enough soil to completely cover them.

Leave about 2 inches of space at the top of the bag to accommodate the growing plants. This layer of soil helps protect the seed potatoes, provides them with the necessary nutrients, and encourages healthy growth. Properly covering the seed potatoes sets the stage for a successful potato crop in your bag.

The Right Way of Watering

Proper watering will promote healthy potato growth and lead to a successful harvest in your bag.

Water Thoroughly: 

Watering your seed potatoes in the bag is crucial for their growth. After planting and covering them with soil, ensure the soil is evenly moist but not waterlogged. To do this, water the bag thoroughly, allowing the water to penetrate the soil and reach the root zone. Check the moisture regularly and water whenever the top inch of soil feels dry to the touch. Keep the soil consistently moist, especially during hot and dry periods.

Water Regularly:

Throughout the potato plant’s growth season in the bag, it’s essential to water regularly to ensure healthy development. Be consistent with watering, keeping the soil evenly moist but not waterlogged. Proper watering helps the plant develop strong roots and encourages the formation of tubers. By maintaining a regular watering schedule, you’ll support a successful potato crop in your bag, leading to a bountiful harvest.


Start by applying a balanced, slow-release fertilizer when the plants are about 6 inches tall. Follow the package instructions for the correct dosage. Apply the fertilizer evenly over the soil’s surface, avoiding direct contact with the potato plants. Then, water thoroughly to help the nutrients reach the roots. Repeat the fertilization process when the potato plants start flowering, as they require additional nutrients during this critical phase of tuber development.
