How to Get Potatoes to Sprout Eyes: 3 Easy Ways
The eyes on a potato are actually dormant buds that have the potential to develop into new shoots and stems, allowing the plant to propagate asexually. They are crucial for potato propagation.
When the conditions are favorable, these dormant buds receive signals to sprout and grow into new plants. Each sprout that emerges from an eye can become a new potato plant. It is essentially a clone of the parent plant.
Let’s take a detailed look at the 3 ways how to get potatoes to sprout eyes:
1. Light-Induced Germination: Pre-Planting Phase (17-20 Days)
This germination process is ideal for individuals who have access to a spacious, well-lit, and adequately ventilated room with a consistent room temperature.
Procedure
Here is the procedure for this process:
- Remove long white sprouts from stored seed potatoes.
- Place 2 to 3 tubers in a well-lit spot with room temperature +18-23 °C. Ensure good ventilation.
- Flip the potatoes to expose the darkened areas to light when the first eye sprout appears. Repeat this process for even sprout development.
- The sprouts will be short and dark-colored after 15 to 16 days. Carefully transfer the sprouted potatoes to shipping boxes and plant them in the ground.
2. Moist Environment Germination (7-10 Days)
This method facilitates root formation on eye sprouts and enhances tuber moisture retention. It is the fastest process and is really beneficial in dry seasons. This approach doesn’t demand a large, brightly lit room.
Procedure
Here’s how to do it:
- Arrange the sprout potatoes in 3 to 4 layers, with wet sawdust or hummus. Store them in wooden boxes or baskets to protect the eye sprouts during transportation to the planting site.
- Water the boxes evenly using a watering can with a sieve. This will make the entire surface moist. If the top layer of potatoes dries out during germination, you can add moisture with time.
- Allow the boxes to sit in a room with a temperature of +14-16 °C for 7 to 10 days.
- It’s time to plant the seed potatoes when the shoots appear.
3. Polyethylene-Enclosed Germination (10-15 Days)
The use of translucent small plastic bags creates a greenhouse effect. It is similar to what happens in a greenhouse and results in the relatively rapid emergence of eye sprouts. The bags are also called T-shirts as well.
Procedure
Follow these steps:
- Use scissors to create small ventilation holes in the plastic bags, spaced approximately every 15 to 20 cm.
- Take 8 to 10 and then plant unsprouted potatoes in every bag, tie them securely, and hang them in a well-lit room at room temperature.
- Flip the bags once a day to ensure even exposure to light.
- The sprout potatoes will reach a normal length which is about 2 to 4 cm in about 10 to 15 days. Transfer the potatoes from the bags to sturdy containers like boxes. Prepare them for transportation to the designated drop-off point.
Strategic Timing To Potato Eyes Sprouting
Timing is a crucial aspect of successfully sprouting eyes on potato tubers. The right timing ensures that the sprouts emerge at the ideal stage for planting and result in healthy, productive plants. Here are some strategic timing considerations:
1. Pre-Sprouting (Chitting Potatoes)
Start the pre-sprouting process about 4-6 weeks before the intended planting date. This gives the potato eyes enough time to develop strong sprouts before they are planted in the ground.
Consider the average last frost date in your region and count backward to determine the best time to begin pre-sprouting.
2. Planting Time
Wait until the soil temperature reaches around 45-50°F. Planting the sprout potatoes in colder soil may result in slow or uneven sprouting of the eyes.
3. Growing Season Duration
Consider the length of your growing season when deciding when to plant. Potato eyes typically take 70-120 days to mature, depending on the variety. Ensure that the growing season is long enough to allow the potato eyes to reach maturity.
4. Harvest Time
Plan the planting time of the sprouting potatoes so that you can harvest potatoes at the desired stage. For new potatoes with smaller eyes and a tender texture, you can harvest them earlier, while for full-sized mature potato eyes, wait until the foliage has died back.
5. Successive Plantings
To extend your harvest, consider successive plantings every 2-3 weeks:
- This staggered approach ensures a continuous supply of fresh potatoes throughout the growing season.
- Strategically timing your pre-sprouting, planting, and harvesting, you can optimize the conditions for successful sprouted eyes.

Creating Optimal Environmental Conditions for Sprouting Eyes
Creating optimal environmental conditions for sprouting eyes is crucial to ensure healthy and vigorous potato growth. Here are the key factors to consider, along with subheadings to organize the information:
1. Temperature and Light
Keep the potatoes at a consistent room temperature of around 65-75°F. Avoid exposing them to extreme heat or cold, as this can inhibit sprouting or lead to spoilage.
Potatoes need some light to produce chlorophyll and green leaves. Direct sunlight can cause greening and the production of toxic solanine. Store potatoes in a cool, dark place to prevent this.
2. Air Circulation and Humidity
Provide adequate air circulation around the potatoes to prevent moisture buildup and potential rotting. Use a well-ventilated area or a shallow tray or basket to store them. High humidity can encourage mold and rot on the potatoes. Ensure the storage area is relatively dry, but not excessively arid.
3. Proper Planting and Spacing
When planting sprouted potatoes, position them in the soil with the eyes facing up. This encourages the sprouts to emerge from the correct side. Provide adequate spacing of about 8-12 inches between each potato. It will allow the plants to grow and access sufficient nutrients and water.
4. Watering and Soil Moisture
Potatoes require consistent soil moisture for healthy sprout development. Keep the soil evenly moist, but avoid overwatering to prevent rotting. Applying a layer of organic mulch around the plants helps retain moisture and regulate soil temperature.

Choosing the Right Potato Types
Choosing the appropriate seed potatoes is a crucial step in ensuring successful sprouting. Therefore, you should consider the following factors:
Overcoming Issues with Store-Bought Potatoes
One common issue with store-bought retail potatoes is that they are often treated with chemicals by commercial potato growers.
- These chemicals are applied to prevent the potatoes from sprouting during transportation and on store shelves.
- It hinders their ability to sprout when you want to grow them in your garden.
Another concern with store-bought potatoes is the potential presence of bacteria, fungi, and virus strains.
- These pathogens can easily infect and spread in your garden.
- The introduction of such infections can create an unfavorable environment for healthy gardening.
The Advantages of Organic Seed Potatoes
When it comes to achieving healthy sprouting, organic seed potatoes play a crucial role in reducing the risks of diseases and infections.
Many gardeners find seed potatoes a more cost-effective choice in the long run. Certified seed potatoes offer the advantage of being disease-free.
Guarding Against Pests and Diseases
While potatoes are not naturally resistant to pests and diseases, there are measures you can take to protect and support their growth:
Pests
Potatoes are susceptible to various pests and diseases, including the Colorado potato beetle, potato leafhopper, and wireworms.
1. Colorado Potato Beetle
Colorado beetles cause damage by chewing on potato sprouts and leaves. While overwintered adult beetles mainly focus on laying eggs, the larvae are the primary concern. Crop rotation is an effective organic method to control these pests since they do not fly.
If you plant potatoes in different locations each year, it can disrupt their life cycle. Manually removing the beetles is also an option. If needed, you can use pesticides like Spinosad to eliminate them.
2. Potato Leafhopper
Potato leafhoppers extract sap and nutrients from potato plants. As a last resort, pesticides or introducing beneficial insects like ladybugs should be considered.
It’s worth noting that leafhoppers overwinter in garden waste, so removing such materials can aid in reducing their population.
3. Wireworms
Wireworms are particularly troublesome pests that attack seed potatoes, roots, and tubers. Managing their presence can be achieved through pesticide applications, promoting natural enemies, and implementing crop rotation practices.
A creative approach involves burying halves of potatoes about an inch deep and checking them after a day or two to remove any wireworms found.
Deseases
Potato blight and potato scabs are two significant fungal infections that can cause severe damage to potato crops.
1. Potato Blight
Potato blight is highly contagious and can spread easily through wind, water, and insects. This rapid transmission can lead to the widespread infection of nearby gardens and potato plants.
2. Potato Scab
On the other hand, potato scabs are more visually apparent. They are characterized by raised dark brown patches resembling warts on the potato surface.
- The infection is typically spread through water, wind, and contaminated farming equipment.
- Both of these diseases (Blight and Scab) have the potential to build up fungal spores in the soil over time, creating a persistent problem.
- In areas suspected to be infected, it is crucial to take precautions and avoid planting potatoes for at least 3 years. This period allows for the soil to naturally recover and reduces the risk of further contamination.
5 Handy Tips For Successfully Storing Potatoes Long-Term
If you want to store potatoes and want success, then follow these tips:
- Store potatoes in a cool, dry place to ensure their longevity.
- The ideal temperature range for potato storage is between 45 and 50 degrees Fahrenheit.
- Basements or garages are suitable locations for storing potatoes.
- Refrigerators or freezers can also be used to store potatoes for up to three months.
- Consider creating a root clamp by digging a hole in the ground and lining it with hay and straw. This method provides a cool environment for potatoes and can extend their storage life to three months.
