How to Grow Organic Potatoes – Soil Preparation for Planting
If you want to master how to grow organic potatoes, soil preparation is one of the most important factors to ensure a productive and healthy harvest. Well-structured soil provides the essential nutrients for potato development, improves moisture retention, and prevents issues like compaction and diseases that can compromise production.
Unlike other crops, potatoes need slightly acidic soil, with a pH between 5.5 and 6.5, to absorb nutrients properly. If the soil is too alkaline or too acidic, it may be necessary to correct it with appropriate organic inputs.
In addition, soil fertility must be ensured by adding organic matter, such as well-matured compost and aged manure, which enrich the soil and provide the necessary nutrients throughout the plant’s cycle.
Another essential point is drainage. Potatoes do not tolerate waterlogged soils, as excess moisture can promote fungal diseases like blight and cause the tubers to rot. To avoid these problems, the use of raised beds or ridges is recommended, as they improve soil aeration and reduce the risks of waterlogging.
If you want to better understand how to test and correct soil pH, which are the best organic fertilizers for potatoes, and how to structure highly productive soil, all this detailed information is available in the Complete Guide to Growing Organic Potatoes.
How to Grow Organic Potatoes – Planting Organic Potatoes
Now that the soil is prepared, it’s time to start planting! If you want to ensure an abundant and high-quality harvest, it is essential to follow the best planting practices for organic potatoes. Learning how to grow organic potatoes properly from the beginning makes all the difference for healthy plant development and well-formed tubers.
The first step is to choose certified seed potatoes, which ensure greater plant health and prevent the introduction of diseases into the soil. If you are using larger potatoes, you can cut them into pieces, as long as each one contains at least one “eye”—the spot where the sprouts will emerge. However, before planting, these pieces should be allowed to heal for 24 to 48 hours, forming a protective layer that reduces the risk of rotting.
Another crucial aspect is spacing and planting depth. Potatoes should be buried 10 to 15 cm deep, with a spacing of 30 cm between each plant. The spacing between rows should be at least 75 cm, ensuring enough room for tuber development and making it easier to manage the crop throughout the plant’s cycle.
In addition, factors such as soil temperature and the time of year directly influence germination and plant growth.

How to Grow Organic Potatoes – Watering and Irrigation
Knowing how to manage irrigation properly is one of the essential factors for success in growing organic potatoes. Anyone who wants to learn how to grow organic potatoes needs to understand that the amount and frequency of watering can directly influence plant growth, tuber formation, and even disease resistance.
Potatoes require a consistent level of soil moisture, especially during the sprouting and tuber formation stages. Lack of water can cause water stress, resulting in smaller and cracked potatoes, while excess moisture can lead to root rot and promote fungal diseases such as blight and bacterial soft rot. Therefore, maintaining balanced irrigation is crucial for healthy development.
A common mistake among many growers is using overhead sprinklers, which leave the foliage wet and create a favorable environment for disease development. Instead, the ideal is to use drip irrigation systems or soaker hoses, which keep the soil moist without wetting the plant’s aerial parts. In addition to being more efficient, these methods help conserve water and ensure even moisture throughout the crop cycle.

How to Grow Organic Potatoes – Organic Fertilization for Potatoes
If you want to achieve a productive and high-quality harvest, understanding how to properly nourish your plants is essential. In organic farming, providing the right nutrients at the right time makes all the difference. For those looking to learn how to grow organic potatoes, balanced fertilization is one of the key pillars of success.
Potatoes have specific nutritional requirements at each stage of development. In the initial stage, when the plant needs to grow and form a strong structure, it is essential to provide nitrogen-rich fertilizers, which stimulate leaf and stem development.
In the flowering and tuber formation stages, however, excess nitrogen can reduce productivity by causing the plant to focus its energy on vegetative growth instead of forming potatoes. At this point, it’s best to reduce nitrogen and increase potassium, which strengthens the tubers and improves their quality.
In organic agriculture, natural fertilizers are the best alternative for maintaining a balanced and productive soil. Ingredients such as bone meal, fish emulsion, and homemade biofertilizers are excellent options for supplying the necessary nutrients without resorting to chemical inputs. Additionally, green manure and crop rotation can contribute to soil regeneration and a continuous supply of organic matter.

How to Grow Organic Potatoes – Mulching and Weed Control
One of the secrets to successful organic farming is keeping the soil protected and free from competition with unwanted plants. In potato cultivation, weeds can become a major issue, as they directly compete for water, light, and nutrients, reducing plant growth and compromising production. Anyone looking to learn how to grow organic potatoes must adopt effective weed control strategies without relying on chemical herbicides.
Mulching is one of the best practices to keep the soil moist, regulate temperature, and prevent excessive weed growth. Applying a thick layer of straw, hay, or crop residues around the plants creates a natural barrier against invasive weeds and also improves moisture retention, reducing the need for frequent irrigation. Moreover, the organic matter released as the mulch decomposes contributes to soil health.
Another effective strategy is manual weeding, which can be done periodically to remove invasive plants without harming the potatoes. Using hoes between the rows makes this process easier and prevents weeds from establishing and spreading. This practice also improves soil aeration, promoting a more favorable environment for tuber development.

How to Grow Organic Potatoes – Hilling and Plant Support
If you want to learn how to grow organic potatoes the right way, you need to understand the importance of hilling in potato development. This practice is essential to stimulate the formation of more tubers and ensure they grow protected from sunlight, preventing them from turning green and toxic due to the presence of solanine.
Hilling should be done when the plants reach about 15 cm in height. Simply pull the soil around the stems, partially covering the base without burying the leaves completely. This process can be repeated throughout the growing cycle to ensure the tubers remain covered and well developed. In addition to boosting production, this technique helps improve soil drainage and reduce weed incidence.
As for support, it is not necessary for most potato varieties, as the plants tend to be more sprawling. However, some varieties with longer stems may grow excessively and topple over, making management more difficult. In such cases, using light stakes or supports can help keep the plants organized, especially when growing in containers or small spaces.

How to Grow Organic Potatoes – Harvesting Organic Potatoes
Knowing the right time to harvest is essential to ensure flavorful, well-developed, and long-lasting potatoes. For those who want to learn how to grow organic potatoes successfully, it’s important to understand that harvesting too early can result in small potatoes with thin skins, while harvesting too late can increase the risk of losses due to pests, diseases, or rotting in the soil.
The ideal time to harvest is when the plant leaves begin to yellow and dry out naturally. This is a sign that the tubers have reached maturity and can be removed from the soil. To harvest properly, use a shovel or garden fork, digging carefully around the plant to avoid damaging the tubers. Ideally, this should be done on a dry day to prevent excess moisture from compromising the storage quality of the potatoes.
After harvesting, it’s essential to handle the potatoes with care. Potatoes that are bruised or cut during removal from the soil have a shorter storage life and may rot more quickly. To strengthen the skin and improve preservation, it is recommended to let them cure for a few days in a cool, dark, and well-ventilated environment. This process helps heal minor damage and extends the tubers’ shelf life.
