Growing Food – Potatoes

If you’re looking to grow your food, consider planting potatoes. They’re a high-yield plant that’s also easy to grow and can be stored for months. Potatoes are a must-have for any garden. Additionally, growing them at home is worth it since they’re on the “dirty dozen” list.

It’s nearly impossible to create a comprehensive how-to guide for growing potatoes since there are countless methods available, and your approach will vary based on your unique preferences and conditions. Therefore, find the best method for you and start growing potatoes.

Potato varieties

When shopping at a supermarket, it may seem like only two types of potatoes are available: red and white. However, numerous varieties have distinct differences in color, texture, and flavor. Additionally, these varieties can be categorized as early, mid-season, or late.

There are many exciting and tasty potato varieties to choose from. To get inspired, take a look at Eagle Creek, a potato seed farm just north of us, offering over 40 different potato varieties.

In a short growing season, early varieties might be your best choice. They should be ready to harvest in 50-70 days after planting. Norland potatoes – an early variety, grow well here in our short summers and store well. We usually grow a few rows simply because they are so non-fail. 

Mid-season varieties typically mature within 70-90 days. Yukon Gold is a popular mid-season potato. Purple Caribe has satiny blue-purple skin; whiter-than-white flesh. Yum!

Our favorite potatoes to grow is German Butterball – a late variety. It has a fantastic buttery flavor and tastes best small. We usually leave them in the ground till the frost kills the tops. This way, we also get a good amount of bigger potatoes. German Butterball is an heirloom potato. Great for eating fresh or for storing throughout the winter.

If you want something exotic, grow Russian Blue. Those dark purple potatoes taste just like a good potato but will be a conversation topic at your dinner table. Plus, there is an Anti-Inflammatory effect of purple potatoes.

Potatoes, just like tomatoes, can be determinate (bush type) and indeterminate (vine type) varieties. Early and mid-season potato varieties are usually determinate, while late varieties are often indeterminate. However, this does not imply that indeterminate potatoes will grow tall like tomatoes. Instead, it simply means that they continue producing potatoes along the stem. To ensure the best yield, it is recommended to hill them a few times during the growing season or grow them vertically in a container. 

Seed potatoes

Every potato, by design, is a seed potato. But since not every potato has been grown naturally, getting good seed potatoes for your garden is a good idea. 

You can easily save your seed potatoes. Healthy, medium-sized potatoes make great seed potatoes. Also, turned green potatoes make good seed potatoes, which are not suitable for food but store well. Every few years, if the production decreases, you can bring in new seed potatoes.

Does size matter? Rumor has it that if you plant big potatoes, you get big potatoes; if you plant small potatoes, you get small potatoes. Other growers claim that small seed potatoes bring bigger potatoes. We prefer using the bigger potatoes for food and mid-sized potatoes for planting. 

Chitting seed potatoes

Seed potatoes can be prepared for planting by laying them out in a bright location and letting them grow sprouts. This is called chitting. Potatoes do not have to be sprouted; it is a good way to speed up germination. Instead of keeping them in a dark space where they grow long sprouts, bring them into light and let them grow healthy green sprouts. 

In the picture above, you see three seed potatoes, all three are great for planting. The first has been stored in a dark room, so the sprouts are weak and white. They will grow, though. The second has been sprouted in a bright room for about a month. The sprouts are green and ready to grow, this would be the ideal situation. The third has been in a bright room for four months; the sprout is much bigger and also ready to grow. 

Can seed potatoes be out in the light for months? We tested it. As you see in this picture above, in 2 months, the potatoes grew small green sprouts. It is slow sprouting compared to potatoes stored in a dark place and grows those long useless sprouts. If you have less than ideal conditions to store seed potatoes, bring them out to light. 

These long sprouts grew at the same time period, stored in an open box in the cold room. This is the Russian blue variety in the picture before, seen in the middle. You see, not just the size of the sprouts is different, the potatoes are also dehydrated and shriveled. Those will still grow, but we prefer the healthy sprouted better if we have a choice. 

You can use an egg carton or a harvest carton to keep seed potatoes dry. Chitting potatoes for 6 to 8 weeks before planting is sufficient. If you have big seed potatoes, you can cut them in half or make 3 out of one. Make sure each section has a few eyes to grow. Cut them beforehand so the cut dries over and does not start to rot in the ground. 

Preventing disease in seed potatoes

If you suspect your seed potatoes are diseased or come from unreliable sources, it’s important to prevent the potential spread of disease in your garden. Is this achievable? To some extent, yes. 

First, let the potato sprout. This one in the picture has been out in the light for months. It does not have to be that long. Just enough to see the main healthy sprout. Cut the rest of the potato back so that only the healthy sprout is left, as shown in the picture above. Let the cut dry for a few hours and plant.

Different ways to grow potatoes

Potatoes can be grown in many ways. I do not think there is a right or wrong way to grow potatoes. It mostly depends on your possibilities and preference.

Traditionally potatoes are planted in rows 3ft (ca. 91 cm) apart. The space between potatoes within a row depends on the variety. Early varieties can be planted close together (6″-10″), as they tend to have a low number of tubers per hill. Mid-season varieties are generally planted 8″ to 12″ apart. Late Season Varieties & Fingerling Varieties should be planted 12″ apart or more.

Pulling up the soil around the potato plant stems is recommended once or twice during the growing season. This helps to create hills around the plant, which allows for easier expansion of the developing tubers. Additionally, it prevents the potatoes from being exposed to sunlight, which can cause them to turn green.

Potatoes can also be mulched instead of hilled with soil. It makes for an easier harvest. If you are growing a no-till garden, the soil is already covered with mulch. However, potatoes will benefit from more mulch than your usual crop.

The pioneer in this easy mulching method was Ruth Stout. Here’s her book: Gardening Without Work. She would lay potatoes on the ground and cover them with hey. In a dry climate burying the seed potatoes a couple of inches into the soil seems to work better than just placing them on the soil and covering them with a thick layer of compost, wood chips, hay, or straw. After experimenting with straw ourselves, we prefer using compost or wood chips. 

Potatoes can also be grown in containers. The idea is to fill the container half full, plant potatoes, and fill up the soil as the potatoes grow. See this enormous harvest of container-grown potatoes. All kinds of containers, bags, or tires can be used. For determinate potatoes, a bucket can work well; for indeterminate, a taller container is better, so you can keep filling them up. 

The Old World Garden Farms adopted the growing of potatoes “container style” in a more natural way. They created Potato Crates from non-treated pallet wood – and were very surprised with the results! Read about it here.

Companion plants and crop rotation

West Coast seeds give these suggestions: Bush beans, celery, corn, garlic, marigolds, onions, and peas all do well planted near potatoes. Avoid planting potatoes near asparagus, Brassicas, carrots, cucumber, kohlrabi, melons, parsnips, rutabaga, squash, sunflower, and turnips. 

It is also known that potatoes and raspberries should not be planted next to each other. The funny thing is that my parents grew all the potatoes we ate for over 20 years in the same spot, always next to a row of raspberries. Back then, there was no internet, and no one told them it was not a good idea ;). 

Needless to say that I don’t take companion planting and crop rotation very seriously. Both are way overrated. Just use common sense for both companion planting and crop rotation. If you have potato disease, it is better to crop rotate next year to avoid the same problem. If the harvest is good, you can plant the potatoes in the same spot.

Personally, we like to rotate for weed control. Potatoes are the best crop to plant in a bed that has had a weed problem. They are such prolific growers that nothing else wants to be close. We usually give the potatoes a whole bed so they can take the space they need.

Potato diseases

Potato scab is one of the most common potato diseases. In common language, it might also be known as blight. However, scab and blight are not the same. Scab is a bacterial disease that only affects the outer skin of the potato. It looks worse than it is. Potatoes are still edible and even store well with scabs. Scab occurs if the soil is too dry or if there is too much nitrogen-rich fertilizer.

Potato blight, on the other hand, is a fungus, the worst disease a potato grower can have. Blight develops in warm and humid conditions and is not common in our climate.

Colorado Potato Beetle is a common problem. Thankfully we do not have to deal with this issue here at Northern Homestead. But, we did have some experiences with CPB while living in Virginia. Spraying the beetles was part of Jakob’s job in the summer. It was not our garden, so Jakob did what he was told to do but could see that it did not work. The potatoes died before the beetles did. We visited a great gardener in the next town and were amazed that her garden didn’t have a beetle problem. She was knocking the mature beetles off the plants instead of picking or spraying them. It seemed that she got them early on so they’d have a hard time getting back on the plants to lay eggs. In the morning, she would quickly shake out rows of plants and not see a return of Colorado potato beetles. This method is very simple and worth trying out. 

Wireworms in potatoes seem to be common when transforming a pasture or hay field into a garden. A reader shared with us:  “I did have problems with wireworms, so in the 2nd & 3rd years, about two weeks before planting, I set out traps (a piece of potato on a stick stuck 2” into the soil).”

Harvesting potatoes

When potato plants bloom, it is possible to harvest young potatoes growing underneath. Extract these early potatoes from the side of the plant without damaging or killing it. The flowers of potato plants are quite beautiful. Before people realized the tubers were edible and delicious, the plants were only known for their flowers.

Potatoes that are young have thin skin that thickens once the plant stops growing and begins to die back. This is the ideal time to harvest the potatoes for storage as the skin has fully developed, allowing the tubers to be stored for several months.

If possible, choose a dry period to harvest potatoes for storage. Now it does make a difference what method was used to grow them. The traditional method will involve hard work to dig all those potatoes up. Maybe that is why many easier ways have been developed to eliminate all the back-breaking digging. No matter how you get them out, try not to stab any.

We often harvest our potatoes after the killer frost during the Indian summer. In the picture is an 800g (1.76 pounds) potato and a 250g (o,55 pounds) carrot that we grew in the farm garden.

Storing and preserving potatoes

Potatoes can be stored for months in a burlap potato sack or wooden crate. Let the tubers dry out a bit (just for an hour or two as needed to dry), before storing them. Do not leave potatoes for days in bright light, even worse under sunlight. They will get green.

Potatoes do not need to be washed; they will store better if you don’t. Give them a week or two for drying or “curing” in a warmish (about 60F) but dark place. This will help heal any cuts or bruises and strengthen the skin for long storage. Potatoes need a cool (35 -40F) dark place for storage, even though the dark is more important than the temperature.

When potatoes start sprouting, they will take those sprouts off. It will help them to stay firm longer. I often go twice through all the potatoes to get rid of unwanted sprouts.

Pressure-canning potatoes is another great way to preserve potatoes. It does not have to be done right at harvest time. Store them as long as you think they will store, but before they start growing sprouts, potatoes can be canned. Having canned potatoes on hand during the busy summertime is great.

Cooking potatoes
