Benefits of Growing Potatoes in Straw

Growing potatoes in straw offers several benefits. Firstly, it can save space and labor compared to traditional potato growing methods, as you can easily grow potatoes in containers such as planting bags, making it suitable for small gardens or even urban spaces.

Secondly, straw acts as a natural mulch, helping to retain moisture in the soil and reduce weed growth, reducing the need for frequent watering and weeding. Additionally, straw provides a clean and disease-free medium for growing potatoes, minimizing the risk of soil-borne diseases.

Furthermore, harvesting potatoes grown in straw is relatively easy, as the straw can be easily moved aside to access the potatoes, making the harvesting process less labor-intensive. Lastly, using straw as a growing medium is environmentally friendly and sustainable, as it is a renewable resource and can be easily decomposed or reused as mulch or compost after the growing season.

Preparing the Seed Potatoes

Preparing the seed potatoes is a crucial step in growing potatoes in straw. Before planting, it’s important to inspect the seed potatoes for any signs of damage, disease, or rot. If there are any damaged or diseased potatoes, they should be discarded to prevent the spread of diseases to healthy potatoes. To promote healthy growth, larger seed potatoes can be cut into smaller pieces, each containing at least one “eye” or sprout.

Cutting the seed potatoes should be done a day or two before planting, allowing the cut surfaces to dry and form a protective callus. This helps to reduce the risk of rot or infection when planting in straw. Properly preparing the seed potatoes sets the foundation for a successful potato growing season in straw.

Laying the Straw

Laying the straw is a key step in growing potatoes in straw. After preparing the seed potatoes, spread a layer of straw on the ground or in the planting bags to create a straw bed. The straw should be laid thickly, typically around 15-20 cm (6-8 inches) deep, to provide a soft and insulating bed for the potatoes to grow in.

Make sure the straw is clean and free from any weeds, seeds, or debris that may interfere with potato growth. The straw acts as a natural mulch, helping to retain moisture in the soil, suppress weeds, and protect potatoes from direct sunlight. Properly laid straw provides a cozy and conducive environment for potato plants to establish their roots and thrive as they grow.

Watering and Fertilizing

Watering and fertilizing are essential tasks in growing potatoes in straw. Proper watering is crucial to ensure that the potato plants have enough moisture for healthy growth. The straw and potatoes should be kept consistently moist, but not waterlogged, as excess moisture can cause rot or disease. Water the potato plants regularly, especially during dry periods, and monitor the moisture level to ensure it remains adequate.

Fertilizing is also important to provide the necessary nutrients for the potato plants to grow and produce a good harvest. Before planting, you can incorporate some fertilizer into the straw bed or planting bags. Additionally, you may need to apply additional fertilizer during the growing season, following the manufacturer’s instructions for the specific type and brand of fertilizer you are using.

Generally, fertilizers rich in potassium, phosphorus, and nitrogen are suitable for potatoes. Regularly monitoring and maintaining proper moisture and nutrient levels through watering and fertilizing can help promote healthy growth and maximize the yield of your potato plants.


Harvesting is an exciting and rewarding step in growing potatoes in straw. As the potato plants mature, they will produce flowers and the leaves will start to turn yellow and die back. This is a sign that the potatoes are ready for harvest.

To harvest, carefully move aside the straw to reveal the potatoes nestled within. Using your hands or a garden fork, gently dig out the potatoes, being careful not to damage them. Take care to remove all the potatoes from the straw bed or planting bags, leaving none behind.

Once harvested, allow the potatoes to dry and cure for a few hours in a cool, dry, and well-ventilated area. This helps to toughen their skin and extend their storage life. Brush off any excess straw or soil, but avoid washing the potatoes as this can shorten their shelf life.

After curing, store the harvested potatoes in a dark, cool, and dry place, such as a cellar or pantry, to prevent sprouting and rotting. Harvesting potatoes from straw is a satisfying process that can yield a bountiful harvest of homegrown, delicious potatoes for you to enjoy!
