What Are Seed Potatoes? A Comprehensive Guide


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 small tubers. They 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? You can use seed potatoes as seeds for planting. They are not intended for human consumption like regular potatoes. Instead, they serve as the base for a new crop.

You can also use regular potatoes for planting. But they 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

These potatoes have been officially inspected and confirmed to be free of diseases and pests. They are grown under strict standards in certified fields. Certified seed potatoes 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. This ensures they are virus-free and true-to-type.

They are high-quality and reliable. 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 carry viruses and diseases. These 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

Russet, Red Bliss and Yukon Gold are popular choices. You should consider your climate, soil type and intended use. For a warm climate, you can choose a heat-tolerant variety. For example, the Red LaSoda. For a potato salad, Yukon Gold would be more suitable. It has a creamy texture and low starch content.

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.

Where to Buy Seed Potatoes?

You can get them from local garden centers, nurseries and online retailers. Purchase seed potatoes directly from potato farmers is also possible. Make sure they should have good quality without any diseases or pests.

How to Plant Seed Potatoes?

Soil Preparation

Preparing the soil a few weeks before planting. Your potato plants will have the best possible yield. Use well-draining soil rich in organic matters. Make sure the soil pH is 6.0-6.5.

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. Add a thin layer of mulch on top helps retain soil moisture. Finally, pay attention to any potential pests or diseases. Take appropriate measures to prevent them from damaging your plants.

Caring for Seed Potatoes


They need 1-2 inches of water per week. You should water deeply and infrequently. This can encourage deep root growth. Avoid under-watering or over-watering.


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

Disease Prevention

Blight, scab and wilt are common potato diseases. Choosing disease-resistant varieties. Practicing good sanitation in the garden. You can also use crop rotation to prevent these diseases.

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. Dig up a few plants to check if unsure.

The potatoes will be small if harvested too early. They are not suitable for storage. Harvesting too late can lead to larger potatoes with thicker skins. They are more prone to rot and diseases.

Proper Storage Techniques

Place potatoes in a cool place. Make sure the temperature is 45°F-50°F. Store them in a dry environment with proper air circulation. Store them in a dark place. Because light will make potatoes turn green and become toxic.

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.
