Seed potatoes are not seeds but small potato tubers. When you plant seed potatoes, you are planting a potato produced by the plant the previous year. Any diseases or insects that the mother plant may have had are carried over in the seed potato. Sourcing certified seed potatoes ensures that you are starting with disease free potatoes.

Potatoes are a staple crop in my garden…

Potatoes are easy to grow, store well through the winter, and provide a nutritious addition to most of our meals. There is nothing like the flavor of freshly dug potatoes and the knowledge that they were grown in a pesticide free environment in our own backyard garden. According to the United States Potato Board, one medium-size potato is only 110 calories and provides a healthy source of potassium, iron, vitamin C, and vitamin B6. Consuming potatoes with the skins on contributes 2 grams of fiber.

Last year’s harvest was less than stellar and I vowed that I would purchase some fresh seed potatoes the following year. The last few years, I reserved part of the harvest to use as seed the following year. This is ok as long as you don’t have any trouble with disease and you have an ideal area to store them through the winter. I noticed that each year, the quality of the plants diminished and size of the tubers decreased. My goal in the garden is to product the greatest yield that I can, so it was time to use fresh batch of seed potatoes this year.

How much potato seed do you need?

Depending on the variety, and if grown in well-balanced soil and optimum growing conditions, one pound of seed potatoes will produce about 10 pounds of potatoes. One pound of seed potatoes will plant about a 6-8 foot row. One pound of fingerling potatoes will plant about 12-16 foot row.

Maine sources for seed potatoes:

Here in Maine we have a lot of mail order sources to turn to for our seed potatoes: Fedco’s Moose Tubers, Johnny’s Selected Seeds, Maine Potato Lady, Wood Prairie Farm, and Pinetree Garden Seeds to name a few. Usually, you have to order early and there are dangers of certain varieties selling out quickly. It was only a couple years ago that I shopped a little smarter. I found that if I could be patient, my local farm and feed stores sold Maine Certified Seed Potatoes later in the spring. Shopping at a local store allows me to not only save on the shipping cost but I can select my own potatoes.

Check your local garden centers, plant nurseries, and farm stores
for certified seed potatoes once spring arrives.

Sourcing certified seed potatoes ensures that you are starting with disease free potatoes.Each state has their own process for certifying seed potatoes. I like to start with certified seed potatoes because this ensures that the seed is disease and insect free, a true variety, and adapted to our local growing conditions.

There is a three-step process to qualify as “Maine Certified.” Even though there are other challenges to growing potatoes, beginning with certified seed potatoes is my first step of growing a successful crop. If the crop grows well with no disease, I try to save some of the smaller tubers to use for the following growing season.

This year, I turned to my local Paris Farmer’s Union in Portland, Maine for my seed potatoes. It was an exercise in patience because of our colder than normal spring, the shipment was delayed because of the danger of the tubers freezing in the truck overnight. Finally, the potatoes arrived. Even though I had not purchased any for several years, the price remained the same, 69¢/pound. I selected the smallest tubers and weighed five pounds each of Red Norland, an early variety and Kennebec, a late variety.

Once I arrived home, the seed potatoes were spread out in a warm area to encourage sprouting. This is also known as chitting or greensprouting and can give your potatoes a head start before they get into the soil. See Chitting Potatoes Gives Them a Head Start.

  1. What if I want to grow late fall into the winter in a small balcony greenhouse? I’m thinking start late Sept? Would I be able to get seed potatoes that late or would I use organic potatoes from the market?

  2. 69 c a pound is so cheap. Here you are lucky to get them for a little over a dollar a pound and that is if you can find seed potatoes at all. Not many places sell them. And mail order potatoes costs so much.

    1. Daphne, I did the mail order route the first year and it was expensive. The second year, I ordered locally from Pinetree seeds and was able to pick them up and save on shipping, but these were still more expensive then my local farm and feed store. I was tempted to buy some for eating too.

  3. I love potatoes, but have yet to grow them – In truth, I’m kind of intimidated by them. Not sure why but they just seem like a tricky crop to grow. Once I have more beds to play around in, I’m sure I’ll get over my “issues” and take the plunge.

    1. Margaret, you should give potatoes a try. Later in the week, I will be posting different ways they can be planted shared by some of my blogging friends.

    1. I am glad I got the sprouted potatoes planted because they are getting a nice watering right now. Also, it will break up the potato planting process a bit. Double digging is really hard. Hopefully, all will grow well.

  4. Lucky you! We don’t have a good local source for seed potatoes. I always end up ordering them from Maine. I am hoping that I will have enough stored this winter to plant some next spring.

    1. I discovered this year that if I can wait until late April, I have several local farm stores where I can purchase Maine certified seed potatoes.

      Storing seed potatoes has been hit or miss for me. The first year I tried, they didn’t make it until planting time. This year was total accidental. I will try to save some seed for next year, but it is nice to know I have a local source if they don’t make it.

  5. Always good to find a local source of supplies – saves on shipping costs and usually is just cheaper too. I like supporting local businesses where I can as well.

    1. I will definitely be purchasing seed potatoes locally from now on. Along with the price difference, I liked being able to sort though and choose the ones I was purchasing.
