How to Grow Potatoes: A Step-by-Step Guide for Success

Growing potatoes in my garden has been one of the most rewarding experiences I’ve had as a home gardener. There’s something magical about planting a small, unassuming seed potato and watching it transform into a lush, green plant that eventually yields a bountiful harvest of delicious tubers.

When I first started growing potatoes, I was amazed by the sheer variety of options available. I had no idea there were so many different types of potatoes beyond the usual suspects found at the grocery store. From creamy, buttery fingerlings to starchy, fluffy russets, the world of potatoes is vast and exciting.

One of the things I love most about growing potatoes is how easy and low-maintenance they are. Sure, they can be a bit prone to disease, but with the right care and attention, you can minimize those risks and enjoy a fantastic harvest. Plus, there’s nothing quite like the joy of digging into the soil with your bare hands and uncovering a treasure trove of fresh, homegrown potatoes.

In this article, I’ll share everything I’ve learned about growing potatoes over the years. From choosing the right varieties to planting, caring for, and harvesting your crop, I’ll guide you through the entire process step by step. Whether you’re a seasoned gardener or a complete beginner, you’ll find plenty of tips and tricks to help you grow the best potatoes of your life.

So, grab your gardening gloves, and let’s dive into the wonderful world of growing potatoes at home!

Choosing the Right Potato Varieties to Grow

When I first started growing potatoes, I was overwhelmed by the sheer number of varieties available. However as I learned more about the different types and their characteristics, I realized that choosing the right varieties is key to a successful harvest.

Potatoes are typically categorized by their maturity dates, which determine when they’ll be ready to harvest. Let’s take a closer look at the three main categories:

Early Season Potatoes

If you’re impatient like me and can’t wait to sink your teeth into fresh, homegrown potatoes, then early-season varieties are the way to go. These potatoes are ready to harvest just 60-80 days after planting, making them perfect for those of us who want a quick turnaround.

Some of my favorite early-season varieties include:

• Red Norland: These small, round potatoes have smooth, red skin and white flesh. They’re great for boiling, roasting, or making potato salad.
• Yukon Gold: With their buttery, yellow flesh, and slightly sweet flavor, Yukon Golds are a versatile variety that’s perfect for mashing, baking, or frying.

Mid-Season Potatoes

If you’re willing to wait a bit longer for your harvest, mid-season potatoes are a great choice. These varieties are ready to harvest 80-100 days after planting and tend to have higher yields than early-season potatoes.

Some of my go-to mid-season varieties include:

• Kennebec: These large, oval potatoes have smooth, buff-colored skin and white flesh. They’re perfect for baking, frying, or making french fries.
• Red Pontiac: With their deep red skin and white flesh, Red Pontiacs are a classic variety that’s great for boiling, roasting, or making potato salad.

Late Season Potatoes

If you’re looking for potatoes that will store well through the winter, late-season varieties are the way to go. These potatoes take the longest to mature, typically 100-120 days after planting, but they reward your patience with big, flavorful tubers that will keep for months in storage.

Some of my favorite late-season varieties include:

• Russet Burbank: These large, oblong potatoes have thick, russetted skin and white flesh. They’re perfect for baking, mashing, or making french fries.
• German Butterball: With their golden, buttery flesh and slightly nutty flavor, German Butterballs are a gourmet variety that’s perfect for roasting or mashing.

No matter which varieties you choose, the key is to select the ones that best fit your growing conditions, cooking preferences, and storage needs. Don’t be afraid to experiment with different types until you find your perfect potato match!

Preparing to Plant Potatoes

Now that you’ve chosen your potato varieties, it’s time to get your hands dirty and start preparing for planting. Trust me, a little bit of prep work goes a long way in ensuring a bountiful harvest.

Selecting and Preparing a Planting Site

When it comes to selecting a planting site for your potatoes, there are a few key things to keep in mind. First and foremost, choose a spot that gets full sun. Potatoes need at least 6-8 hours of direct sunlight per day to thrive.

Next, make sure your planting site has well-draining soil. Potatoes hate sitting in waterlogged soil, which can lead to rot and disease. If your soil is heavy or clay-like, consider adding some organic matter like compost or aged manure to improve drainage.

Finally, avoid planting potatoes in the same spot year after year. This can lead to a buildup of disease and pests in the soil. Instead, practice crop rotation by planting potatoes in a different spot each year, ideally one that hasn’t grown potatoes or other members of the nightshade family (like tomatoes or peppers) in the past 2-3 years.

Soil Requirements for Growing Potatoes

Potatoes are heavy feeders, which means they need plenty of nutrients to grow big and strong. Before planting, it’s a good idea to have your soil tested to see what nutrients it may be lacking. You can do this by sending a soil sample to your local cooperative extension office or using an at-home soil testing kit.

In general, potatoes prefer slightly acidic soil with a pH between 5.0 and 6.5. They also need plenty of nitrogen, phosphorus, and potassium to support healthy growth and tuber development.

If your soil is lacking in nutrients, you can amend it by adding a balanced, slow-release fertilizer or organic matter like compost or aged manure. Just be sure to work any amendments into the soil at least a few weeks before planting to give them time to break down and integrate.

Preparing Seed Potatoes for Planting

Before you can plant your potatoes, you need to prepare your seed potatoes. Seed potatoes are simply small, whole potatoes or potato pieces that are used for planting.

If you’re using whole-seed potatoes, make sure they’re about the size of a chicken egg. If they’re larger than that, you can cut them into smaller pieces, making sure each piece has at least 2-3 “eyes” (the small buds that sprout into new plants).

Once you’ve cut your seed potatoes (if necessary), it’s a good idea to let them “cure” for a day or two before planting. This allows the cut surfaces to dry out and form a protective layer, which can help prevent rot and disease.

To cure your seed potatoes, simply spread them out in a single layer on a tray or newspaper in a cool, dry place out of direct sunlight. After a day or two, they should be ready to plant!

Planting Potatoes

Alright, you’ve got your seed potatoes ready to go, and your planting site is prepped and waiting. Now comes the fun part: putting those spuds in the ground and watching them grow!

When to Plant Potatoes

Timing is everything when it comes to planting potatoes. You want to wait until the soil has warmed up to at least 45°F before planting, which typically happens a few weeks before your area’s last frost date.

In my neck of the woods, that means planting potatoes in early to mid-spring, usually sometime in March or April. But if you live in a warmer climate, you may be able to plant as early as February or as late as May.

How to Plant Potatoes

When it comes to planting potatoes, there are a few different methods you can use. My personal favorite is the “trench method.”

To plant using the trench method, dig a shallow trench about 6 inches deep and 3 feet apart. Place your seed potatoes in the trench, spacing them about 12 inches apart. Then, cover the potatoes with about 4 inches of soil.

As the potato plants grow, you’ll want to “hill up” the soil around them. This means mounding additional soil around the base of the plants as they get taller, leaving just the top leaves exposed. Hilling helps protect the developing tubers from sunlight (which can turn them green and bitter) and encourages the plants to produce more potatoes.

Another method is the “scatter method,” where you simply place your seed potatoes on the soil surface and cover them with a thick layer of organic mulch, like straw or leaves. As the plants grow, you’ll add more mulch to hill them up.

Planting Potatoes in Containers

No garden space? No problem! Potatoes are one of the easiest vegetables to grow in containers.

To plant potatoes in containers, choose a pot or grow bag that’s at least 18 inches deep and 12 inches wide. Fill the bottom 6 inches of the container with a well-draining potting mix, then place your seed potatoes on top and cover them with another 4 inches of mix.

As the plants grow, continue to add more potting mix to hill them up, just like you would in the garden. Make sure to water your container-grown potatoes regularly, as they’ll dry out faster than those grown in the ground.

One of the best things about growing potatoes in containers is the ease of harvesting. When the plants start to die back, simply dump out the contents of the container and sift through the soil to find your homegrown treasures. It’s like a treasure hunt in your backyard!

Caring for Potato Plants

Congratulations, your potato plants are in the ground and growing like gangbusters! Now it’s time to shift gears and focus on giving them the TLC they need to thrive.

Watering Requirements for Potatoes

When it comes to watering potatoes, the key is to find that Goldilocks zone: not too much, not too little, but just right. Potatoes need consistent moisture to grow well, but they don’t like to sit in waterlogged soil.

I aim to give my potato plants about 1-2 inches of water per week, either from rainfall or irrigation. If you’re not sure how much water your plants are getting, try the “finger test.” Stick your finger about an inch into the soil near your potato plants. If it feels dry, it’s time to water.

One thing to keep in mind is that potato plants need the most water during the flowering stage when the tubers are actively developing. Once the plants start to die back, you can ease up on the watering to help the tubers mature and prevent rot.

Fertilizing Potato Plants

Remember how I said potatoes are heavy feeders? Well, that means they need plenty of nutrients throughout the growing season to support healthy growth and tuber development.

I like to give my potato plants a dose of balanced, slow-release fertilizer at planting time, then follow up with a few side-dressings of compost or aged manure every 4-6 weeks during the growing season.

If you notice your potato plants looking a bit pale or yellowed, that’s a sign they may need a nitrogen boost. You can give them a quick pick-me-up with a dose of fish emulsion or seaweed fertilizer, both of which are rich in nitrogen and other essential nutrients.

Hilling Potatoes for Higher Yields

I mentioned hilling up your potato plants earlier, but it’s worth diving into a bit more detail here. Hilling is the process of mounding soil or mulch around the base of your potato plants as they grow, leaving just the top leaves exposed.

Hilling serves a few important purposes. First, it helps protect the developing tubers from sunlight, which can cause them to turn green and develop a bitter flavor. Second, it encourages the plants to produce more tubers along the buried stem. And third, it helps improve drainage and prevent water from pooling around the base of the plants.

I like to hill my potato plants every 2-3 weeks, or whenever they’ve grown about 6 inches tall. I use a hoe or cultivator to gently mound soil or mulch around the base of the plants, being careful not to damage the roots or stems.

By the end of the growing season, my potato plants are typically growing in mounds that are about 12 inches tall. It’s a bit of extra work, but the payoff in terms of higher yields and healthier plants is well worth it!

Harvesting Potatoes

Is there anything more exciting than finally getting to harvest the fruits (or rather, tubers) of your labor? After months of careful tending and waiting, it’s time to dig up those delicious, homegrown potatoes!

When to Harvest Potatoes

Knowing when to harvest your potatoes is key to getting the best yield and quality. The exact timing will depend on the variety you’re growing and your desired use for the potatoes.

For “new” potatoes, which are small, tender potatoes harvested early in the season, you can start digging around 2-3 weeks after the plants have finished flowering. These potatoes are delicate and don’t store well, so it’s best to use them right away.

For mature potatoes that will be stored for later use, wait until the plants have completely died back and the foliage has turned yellow or brown. This usually happens in late summer or early fall, depending on your climate and the variety you’re growing.

If you’re not sure if your potatoes are ready to harvest, try the “rub test.” Gently rub the skin of a potato with your thumb. If the skin is thick and doesn’t rub off easily, it’s ready to harvest. If the skin is thin and rubs off easily, give the plants a bit more time to mature.

How to Harvest Potatoes

When it comes to harvesting potatoes, there are a few different methods you can use depending on the size of your crop and your personal preferences.

For a small harvest, you can simply use your hands to dig around the base of the plants and gently pull out the tubers. This method works well for new potatoes or for harvesting a few potatoes at a time for immediate use.

For a larger harvest, you’ll want to use a digging fork or a spade to loosen the soil around the plants. Start digging about a foot away from the base of the plant to avoid damaging the tubers, then gently lift and sift through the soil to find the potatoes.

One thing to keep in mind is that potatoes can bruise easily, so handle them gently and avoid throwing them into a bucket or onto the ground. I like to place my harvested potatoes directly into a basket or crate lined with a soft cloth to minimize damage.

Curing Potatoes After Harvest

If you plan to store your potatoes for later use, it’s important to cure them properly after harvesting. Curing helps to toughen up the skin and heal any minor cuts or bruises, which can help the potatoes last longer in storage.

To cure your potatoes, simply spread them out in a single layer in a cool, dark, well-ventilated place for about 10-14 days. Ideal curing conditions are around 50-60°F with high humidity.

After curing, gently brush off any excess dirt from the potatoes (but don’t wash them, as this can introduce moisture and lead to spoilage). Then, store the potatoes in a cool, dark place with good ventilation, such as a basement or root cellar.

With proper curing and storage, your homegrown potatoes can last for several months, giving you a delicious and nutritious addition to your meals all winter long!

Storing Potatoes

You’ve put in all the hard work of growing and harvesting your potatoes, so it’s only natural to want to make them last as long as possible. Proper storage is key to keeping your spuds fresh and delicious for months to come.

Ideal Storage Conditions for Potatoes

When it comes to storing potatoes, the goal is to create an environment that’s cool, dark, and well-ventilated. Potatoes are best stored at temperatures between 45-50°F with relatively high humidity (around 90-95%).

One of the best places to store potatoes is in a root cellar or basement that maintains a consistent temperature and humidity level. If you don’t have a root cellar, you can also use an unheated garage, shed, or even a cool closet or pantry.

Wherever you choose to store your potatoes, make sure they’re kept in a dark place away from direct sunlight. Light can cause potatoes to turn green and develop a bitter flavor, which is not only unappetizing but can also be toxic in large amounts.

Another important factor to consider is ventilation. Potatoes need good airflow to prevent moisture buildup and reduce the risk of spoilage. I like to store my potatoes in perforated plastic bags or ventilated bins to allow for plenty of air circulation.

How Long Do Potatoes Last in Storage

The shelf life of potatoes can vary depending on the variety and storage conditions, but in general, most potatoes will last for several months when stored properly.

Early-season varieties tend to have a shorter shelf life than late-season varieties, which are bred for long-term storage. For example, a variety like Red Norland may only last for a few weeks in storage, while a variety like Russet Burbank can last for up to 6 months or more.

To maximize the shelf life of your potatoes, make sure to:

• Cure them properly after harvesting
• Store them in a cool, dark, well-ventilated place
• Avoid storing them with other produce that gives off ethylene gas (like apples or onions), which can cause potatoes to sprout or spoil more quickly
• Check them regularly for signs of spoilage, such as soft spots, mold, or a strong odor, and remove any affected potatoes immediately to prevent the spread of decay

With a little bit of care and attention, you can enjoy your homegrown potatoes for months after harvesting. And trust me, there’s nothing quite like the satisfaction of pulling out a bag of your spuds in the middle of winter and knowing that you grew them yourself!

Troubleshooting Potato Problems

As much as we’d like everything to go smoothly in the garden, the reality is that problems can and do arise. Potatoes are no exception, and several pests and diseases can affect your crop. But don’t worry – with a little knowledge and some proactive steps, you can keep your spuds healthy and happy.

Common Potato Pests and How to Control Them

One of the most common pests that can wreak havoc on your potato plants is the Colorado potato beetle. These little striped beetles and their larvae can quickly defoliate your plants, reducing yields and weakening the plants’ ability to produce tubers.

To control Colorado potato beetles, you can try handpicking them off your plants and dropping them into a bucket of soapy water. You can also use row covers to physically block the beetles from accessing your plants, or try planting “trap crops” like eggplant or green beans to lure the beetles away from your potatoes.

Another common pest is the potato leafhopper, which can cause the leaves of your potato plants to turn yellow and curl up at the edges. Leafhoppers can be controlled with insecticidal soap or neem oil, or by planting resistant varieties like Russet Burbank or Katahdin.

Aphids and flea beetles can also cause damage to potato plants, but they can usually be controlled with a strong spray of water from the hose or by introducing beneficial insects like ladybugs or lacewings to your garden.

Potato Diseases and How to Prevent Them

Potatoes are also susceptible to several diseases, some of which can be devastating to your crop. One of the most notorious is late blight, which caused the Irish Potato Famine in the 1840s.

Late blight is caused by a fungus that thrives in cool, wet conditions. It can cause the leaves and stems of your potato plants to turn brown and wilt, and can also infect the tubers themselves, causing them to rot in storage.

To prevent late blight, it’s important to plant resistant varieties and to practice good cultural controls, such as spacing your plants properly to allow for good air circulation and avoiding overhead watering. You can also use fungicides as a preventative measure, but be sure to follow the label instructions carefully.

Another common disease is potato scab, which causes rough, scabby patches to form on the skin of the tubers. Scab is caused by a bacteria that thrives in alkaline soils, so one way to prevent it is to lower the pH of your soil by adding sulfur or peat moss.

You can also try planting scab-resistant varieties like Russet Burbank or Yukon Gold and avoiding planting potatoes in the same spot year after year to prevent the buildup of disease in the soil.

By keeping an eye out for signs of pests and diseases and taking proactive steps to prevent and control them, you can ensure a healthy and bountiful potato harvest year after year. And if you do run into problems, don’t be afraid to reach out to your local cooperative extension office or gardening community for advice and support.

FAQs

Before we wrap things up, I wanted to take a moment to answer some of the most common questions I get about growing potatoes. If you’re new to potato gardening, these FAQs should help clear up any lingering doubts or concerns you may have.

How Many Potatoes Can You Get From One Plant?

This is one of the most frequent questions I hear from beginner potato growers, and the answer is: it depends. The yield you get from each plant can vary widely depending on factors like the variety you’re growing, the health of the plant, and the growing conditions.

On average, though, you can expect to harvest anywhere from 2-10 pounds of potatoes per plant. Some varieties, like fingerlings or early-season potatoes, may yield less, while others, like russets or late-season potatoes, can produce a more bountiful harvest.

One thing to keep in mind is that the more you “hill up” your potato plants during the growing season, the more tubers they’re likely to produce. So if you want to maximize your yield, be sure to keep mounding that soil or mulch around the base of your plants as they grow.

Can You Grow Potatoes From Store-Bought Potatoes?

Technically, yes, you can grow potatoes from store-bought potatoes. However, I generally don’t recommend it for a few reasons.

First, store-bought potatoes are often treated with sprout inhibitors to prevent them from sprouting on the shelf. This can make it harder to get them to sprout and grow when you plant them in the ground.

Second, store-bought potatoes may not be the best choice for your particular growing conditions or culinary needs. They may be varieties that are better suited to commercial growing operations than home gardens, or they may not have the flavor or texture you’re looking for.

Finally, there’s a risk of introducing diseases or pests to your garden if you plant potatoes that aren’t certified seed potatoes. It’s always best to start with clean, disease-free seed potatoes from a reputable supplier to ensure the health and productivity of your crop.

How Deep Do You Plant Potatoes?

When it comes to planting potatoes, the general rule of thumb is to plant them 4-6 inches deep. This depth allows the plants to develop a strong root system and helps protect the developing tubers from sunlight and pests.

However, the exact depth you plant your potatoes may vary depending on the variety you’re growing and your soil type. In general, early-season potatoes can be planted a bit shallower (around 4 inches deep), while late-season potatoes may benefit from slightly deeper planting (up to 6 inches).

If you’re planting in heavy clay soil, you may want to plant your potatoes a bit shallower to prevent waterlogging and rot. On the other hand, if you’re planting in sandy soil, you may need to plant a bit deeper to ensure the plants have enough moisture and nutrients.

Ultimately, the key is to find the sweet spot that allows your potato plants to thrive in your particular growing conditions. Don’t be afraid to experiment and adjust your planting depth as needed to get the best results.
