What Are Seed Potatoes? A Comprehensive Guide


Seed potatoes are an essential part of any potato farmer's arsenal. These special potatoes ensure the success and quality of future crops. They are essentially the "parent" of all other potatoes. Because they serve as the source for planting and growing new potato plants.

What Is A Seed Potato?

Definition of Seed Potatoes

Seed potatoes are essentially the "seeds" of a potato plant. They are small tubers which contain the genetic material necessary for producing potato plants. These tubers are carefully selected and grown under controlled conditions. They are disease-free and genetically pure.

What Do Seed Potatoes Look Like?

They should have healthy eyes or sprouts that will eventually grow into potato plants. These eyes are small indentations on the surface of the potato. The size of seed potatoes can vary. But they are typically smaller than a regular baking potato.

Seed Potatoes vs Regular Potatoes

Are seed potatoes different from regular potatoes? Seed potatoes are specifically grown to be used as seed for planting. They are not intended for human consumption like regular potatoes. Instead, they serve as the base for a new crop.

While regular potatoes can also be used for planting, seed potatoes are specifically chosen for their quality and suitability for planting. Regular potatoes may not have the same level of genetic purity as seed potatoes. This can result in lower yields and increased diseases.

Benefits of Using Quality Seed Potatoes

Since seed potatoes are grown under controlled conditions. They are unlikely to be infected with diseases that can spread to the entire crop. Quality seed potatoes are carefully selected. They can produce high-yielding crops. You can have a larger harvest and higher profits.

Types of Seed Potatoes

Certified Seed Potatoes

Certified seed potatoes refer to those that have been officially inspected and confirmed to be free of diseases and pests. These potatoes are grown under strict standards in certified fields. They also undergo a rigorous testing process. This ensures they meet the required standards before being sold.

These potatoes also have a unique certification label which indicates their quality and origin. It is usually a blue tag. They are produced from tissue culture or greenhouse-grown plants, ensuring they are virus-free and true-to-type.

The main advantage of using certified seed potatoes is their high-quality and reliability. These potatoes are unlikely to carry diseases or pests. Their germination rate is also higher. They can produce more consistent and uniform plants.

Non-Certified or Farm-Saved Seed Potatoes

Using farm-saved seed potatoes can save costs for you. But it also has potential risks. These potatoes may not undergo the same strict standards and inspections as certified seed. They may be more susceptible to diseases and pests.

These potatoes may carry viruses and diseases which can reduce the crop yield and quality. You should properly inspect and treat their farm-saved seed potatoes to minimize these risks.

Selecting Seed Potatoes for Planting

Choosing the Right Seed Potatoes

Some popular ones include Russet, Red Bliss, Yukon Gold, and Fingerling potatoes. Consider your climate, soil type and intended use when selecting a variety. If you live in a warm climate, you can choose a heat-tolerant variety. For example, the Red LaSoda. For a potato salad, the creamy texture and low starch content of Yukon Gold would be more suitable.

Evaluating Seed Potato Quality

The size, shape and color can provide valuable information about their health and potential yield. Small, round seed potatoes are ideal for planting. They have a higher success rate compared to larger ones. The color should be consistent, with no signs of bruising or decay.

Inspecting the seed potatoes for any signs of disease. This prevents the spread of diseases to your entire crop. Look for any signs of common potato diseases. For example, scab, blight, or rot. Selecting healthy seed potatoes is crucial for a successful harvest. You should not overlook it.

Where to Buy Seed Potatoes?

You should choose a reputable source when purchasing seed potatoes. The potatoes will have good quality and are free from any diseases or pests. You can buy seed potatoes from local garden centers, nurseries and online retailers. It is also possible to purchase them directly from potato farmers.

How to Plant Seed Potatoes?

Soil Preparation

Preparing the soil a few weeks before planting to allow the soil to settle. This ensures the best possible yield from your potato plants. You should use well-draining soil rich in organic matters. The pH of 6.0-6.5 is the best.

Planting Techniques

When planting seed potatoes, follow a few key techniques to ensure successful growth. Plant the potatoes in an area with plenty of sunlight and good air circulation. This will help prevent diseases and promote healthy plant growth.

Proper Spacing and Depth

Space out your seed potatoes properly when planting them. Place each potato about 12 inches apart in a row. The rows space is about 2-3 feet apart. Make sure the small potatoes planting depth is 2-3 inches. The large potatoes planting depth is about 4 inches.

Tips for Successful Planting

Make sure any sprouts on the potato tubers are facing upwards when planting. This will help them grow in the right direction towards the sunlight. Cover the seed potatoes with soil. Then, add a thin layer of straw or mulch on top. This helps retain moisture in the soil. Finally, pay attention to any potential pests or diseases. Take appropriate measures to prevent them from damaging your plants.

Caring for Seed Potatoes


Consistent moisture is crucial for healthy seed potatoes. This means avoiding both under-watering and over-watering. Water your seed potatoes 1-2 inches per week, either through irrigation or natural rainfall. Watering deeply and infrequently is preferred over frequent light watering. This can encourage deeper root growth.


Amend the soil with a balanced fertilizer before planting. Regular fertilization during the growing season. Choose the right type of fertilizer and apply it at the correct times. This can greatly improve the health and yield of your seed potatoes.

Disease Prevention

Potatoes are susceptible to various diseases. They can significantly decrease crop yields. To prevent these diseases, start with healthy seed potatoes and maintain proper growing conditions. Some common potato diseases include blight, scab, and wilt. You can use some strategies to prevent these diseases. For example, crop rotation, choosing disease-resistant varieties, and practicing good sanitation in the garden.

Harvesting and Storing Seed Potatoes

Determining the Right Time to Harvest

Harvest your seed potatoes at the right time to ensure optimal storage and quality. Firm and papery skin, withered and dead back leaves are signs of maturity. You can always dig up a few plants to check for signs of maturity if unsure.

Harvesting too early will result in small, underdeveloped potatoes. They are not suitable for storage. On the other hand, harvesting too late can lead to larger potatoes with thicker skins. They are more prone to rot and diseases.

Proper Storage Techniques

You should store seed potatoes in a cool place with a temperature of 45-50°F. Store them in a dry environment with proper air circulation. Potatoes will turn green and become toxic if exposed to light. You should store them in a dark place.

Washing can damage the protective skin of the potato. This increases the likelihood of rot. Make sure to check your stored potatoes periodically for any signs of rot or disease. Remove any affected potatoes immediately to prevent the spread of spoilage.


What are seed potatoes? They are small potato tubers that are specifically for planting. Prioritize using certified seed potatoes and follow recommended practices. You can produce quality potatoes for consumption with this knowledge.
