How Deep to Plant Potatoes: Everything You Should Know 

Most gardeners love growing potatoes. Not only because they are delicious to eat but also because they are easy to grow. Once you get the seed spacing and depth right, planting and growing potatoes can be a breeze! Before we begin to discuss how deep to plant potatoes, let’s speak about the very how to plant them.

How to plant potatoes

  • Step 1: Choose your potato variety.
    You can grow just about any kind of potato, but there are three main varieties: early, mid, and late. Early potatoes will mature quickly, while late potatoes will take the longest. Mid-season potatoes fall somewhere in between. If you’re going to use them for salads or other dishes that require diced or chopped potatoes, an early or mid-season variety will be best since they’ll be small enough to dice easily. If you want to make roasted or mashed potatoes, a late variety will be better since they’ll be larger and have more flesh.
  • Step 2: Prep your garden bed.
    Potatoes need full sun and well-drained soil to thrive, so pick a spot in your yard with at least six hours of sunlight per day and good drainage. If the soil in your garden bed is particularly sandy or heavy clay, you may want to amend it with some compost or manure before planting. You’ll also need to ensure there are no rocks or roots bigger than a few inches in the soil where you’ll be planting; these can impede the growth of your potato plants.
  • Step 3: Plant your seed potatoes.
    This is the right time to speak about how deep to plant potatoes. Seed potatoes are small potato tubers that haven’t been harvested yet; you can usually find them for sale at nurseries or garden stores. Cut each seed potato into pieces with two eyes (the tiny, brown buds from which the new potato plants will sprout), then plant each piece about eight inches apart and two inches deep in the prepared garden bed. Once they’re all planted, cover them with two inches of mulch (straw is ideal) to keep the soil moist and discourage weeds from popping up around them.
  • Step 4: Water regularly and carefully.
    Potatoes need about an inch of water per week, so water deeply but carefully around each plant once per week unless it rains. Check the soil before watering; if it’s still moist several inches down, hold off until it dries out a bit more. Be careful not to over-water or get the leaves of the plants wet, as both can lead to fungal diseases that can harm or even kill your plants.

How deep to plant potatoes

Have you just started your gardening journey? Are you struggling with growing potatoes? Do you want to know how deep to plant potatoes so they can grow well? 

If you are nodding your head to any (or all!) of the questions mentioned above, you have reached the right blog post! Today, we will tell you the accurate depth for your seed potatoes so that you can enjoy fully grown and delicious potatoes with your family. 

How deep to plant red potatoes?

In general, red potatoes should be planted about 8-10 inches below the soil’s surface. If the potato is not buried deep enough, it will be more susceptible to damage from frost and pests. This depth will protect the potato from most frost and pest damage.

In addition, it is essential to ensure that the potato is not buried too deep in the soil. If the potato is planted too deep, it may not receive sufficient sunlight and water, leading to lackluster growth. When planting red potatoes, it is important to strike a balance between depth and exposure to ensure optimal growth.

So, let’s get started! 

How far apart to plant potatoes

There should be at least 8-12 inches of space between each seed to ensure that they have plenty of room to thrive. Once your potatoes start growing, you will have to create a hill around them and keep on adding extra soil around them to keep them healthy. 

How Far Apart To Plant Potatoes?

You need to ensure that they are planted too close but aren’t too far apart, either. Sounds confusing, right?

Planning the Depth of Your Seed Potatoes 

Before we talk about how deep to plant potatoes, let’s first understand the ideal time for planting your seed potatoes. It is because the time when you plant potatoes will significantly affect the depth and planting method you should choose. 

Potatoes germinate well when the average temperature of the soil is above 40-degree Fahrenheit. Ideally, you should start with your potato plantation at least 2-4 weeks before your region’s last frost of spring. 

Now, when it comes to the right ideal depth for seed potatoes, there are two standard planting methods: Shallow Planting and Deep Planting. 

Let’s quickly look at each of them and give you some more clarity. 

Planning the Depth of Seed Potatoes 

Shallow Planting 

This method will be ideal if you have planted your seed potatoes a bit late. In shallow planting, you will have to plant your seed potatoes in a trach of about 4-inches deep. Then, put the posties in the center and keep the eyes facing upward. 

Deep Planting 

This method is meant for large varieties of potatoes. If you have plenty of time in hand and good soil conditions, deep plating can generate excellent results for you. 

In this method, you will have to plant the seed potatoes 7 to 8 inches deep into the soil and then cover them up with compost and an additional layer of soil. 

Since your seed potatoes are planted quite deep, they will require some time to come up to the surface. So, tend to them and water them properly to ensure they can thrive well.

How to Grow Potatoes in a Container?

You only need a deep container, some well-drained soil, and a seed potato. Once you’ve planted your potato pieces and watered them well, all that’s left to do is wait patiently for 2-4 months until they’re ready to harvest.

Step One: Fill Your Pot with Soil
The first step is to fill your pot with soil. You want to use a light, well-drained mix—potatoes need lots of water, but they don’t like sitting in wet soil. If you’re not sure what kind of soil to use, you can ask for help at your local garden center.

Step Two: Cut Your Potato into Pieces
Once your pot is filled with soil, it’s time to cut up your potato. Each piece should have one or two eyes—these are the places where new potatoes will grow. If your potato doesn’t have any eyes, that’s okay! Leave it out in the open air for a day or two until it sprouts.

Step Three: Plant Your Potato Pieces and Water Well
Now it’s time to plant your potato pieces. Plant them about 8 inches apart, and make sure that the part of the potato with the eyes is facing up. Once all of your pieces are planted, water them well. Keep the soil moist but not soggy—if it dries out too much, your potatoes won’t grow properly.

Step Four: Wait for Your Potatoes to Grow!
The final step is perhaps the hardest—waiting for your potatoes to grow! Depending on the variety of potatoes you’re growing and the temperature outside, it can take anywhere from 2-4 months for your potatoes to be ready to harvest. When they’re ready, you’ll see small “new” potatoes start to form near the base of the plant. To harvest them, dig around carefully with your hands until you find them all. Then enjoy!


So, how deep to plant potatoes? We hope you have found your answer to this question. 

Remember, the depth and spacing of your seed potatoes have the biggest impact on the final quality of your potatoes. Just get these two factors right, and you will be able to enjoy delicious potatoes without any hassle.
