The Sweeter Side of Farming: Grow Your Own Candy Bars

Paul preparing to cut up candy bars for seed

One of the things I like the most about farming is access to some amazing food. Even if I don’t grow a particular crop, my network of producer friends allows me to trade around and cover most of my food needs. The wrinkle is that producing food can be exhausting. I hear a lot of stories about growers who, at the completion of a CSA pick up or farmer’s market day, go home to leftovers or noodles before they fall asleep.

Ask any vegetable farmer and they’ll probably agree; one of their secrets is that lots of organic farms run on three main ingredients: coffee, beer, and candy. I know mine does. Coffee isn’t really suited to New England production, but lots of growers make their own beer. That leaves the candy… We’ve been growing our own for years. It’s fun, really easy, and it saves us money as well.

Candy bar seed pieces ready for planting. Note the distribution of fillings in each piece.


Step 1: Start with the Best

It’s important to start with good stock seed. I always buy new seed every year, mainly because the temptation of our harvest overcomes me, and we have consumed all of our bounty. When cutting your seed pieces, I like to make sure there is a good distribution of fillings in each piece.


Seed far enough apart to produce large bars.

Step 2: Planting

I cut a trench about 6”deep and gently place the seed pieces about 8” apart in the row. It’s possible to control the size of the finished bars by changing your spacing; more room between the plants will give you a “king size” bar, tighter spacing will give you more of a “fun size”. I have found that 8” gives a nice range for me and my farm’s needs. I just barely cover the seed pieces so that they can feel the warmth of the sun and emerge from the soil quickly.



Once the candy bars have developed lush foliage, it’s time to amend with sugar and cocoa, then hill for best yields.

Step 3: Amending for Yield

In about 5 weeks, the plants should be lush green and about 18- 24” tall. At this point there are a few operations that are really important and will contribute to the success of the set. This crop is a heavy feeder, so I side-dress with a good amount of organic sugar and cocoa. My experience is that most soils are pretty deficient in these elements, and many agricultural soil testing services don’t even screen for them. I typically band a 350’ bed with about 100 lbs of a 2:1 mix of sugar to cocoa. I then use a set of hilling discs on a tool bar to get a good hill to cover the plants. When I am done I end up with about 5” of stems above the soil level. This hill covers the developing bars and keeps them out of the direct sun, keeping them cool. We’re all aware of what happens when chocolate is in the sun. Keeping the bars cooler also keeps them cleaner when it comes time to harvest.



Harvesting candy bars is made easy using a candy digger from Hershey, PA

Step 4: Harvest

The last step is the harvest. I cut the tops off the plants 2-3 weeks before I want to dig them. This sends a signal to the bars to set the chocolate, also known as tempering. It gives the chocolate a nice glaze, and makes cleaning post harvest much easier. It also lowers the incidence of bruising if one harvests mechanically, allowing the crop to store almost indefinitely.

I use an old mechanical candy digger that I bought in Hershey, PA. It does a great job of gently lifting the bars out of the soil and making them easy to find. It’s one of my favorite single purpose tools.

If you don’t have access to this kind of an implement, it also works well to dig them by hand.


Step 5: Post-Harvest Handling & Storage

Once the bars are harvested, we brush them lightly before we eat them to get any lingering soil off the surface, and then enjoy (or store them in a cool, dark place).

Every time I have one of these pieces of candy, I am reminded of the sweet times behind us and the sweeter times ahead. I hope the upcoming season brings you and your farm everything that you need.

A Guide to Planting Spring Cover Crops

Planting cover crops is a powerful way to improve your soil. Cover crops perform a host of valuable functions like increasing soil organic matter, fixing nitrogen, breaking up compaction, suppressing weeds and preventing erosion. In this guide we’ll discuss your options for spring cover crops and the benefits of each, when and how to plant, and how to manage the crop once it’s established.

While commercial growers typically use a seed drill or mechanical broadcaster to plant cover crops (followed by mowing and tilling before the crop sets seed), home gardeners can grow cover crops too. For gardeners we recommend planting most cover crops by hand-broadcasting seed over freshly turned soil, then raking in lightly just before a rain. When the cover crop is in flower, just before it sets seed, it should be cut with a scythe or mower, then left as a living mulch for the rest of the season or turned under with a rototiller. Because of the nutrients bound up by the decomposing crop, it is recommended to wait 2-3 weeks after tilling before planting another crop into the area. At this point the cover crop residues will have mostly decomposed, making organic matter and nutrients available to the next crop.

BMR Sorghum-Sudangrass F1

Affording the Farm: Financing for Beginners

Katie Spring and her son Waylon

For beginning farmers, finding the support to start your own farm or to improve your existing farm can seem like a challenge. This challenge doesn’t necessarily let up for the first few years—for perspective, a beginning farmer is defined as someone who has farmed for 10 years or less on their current operation. In other industries, you might feel as if you’ve passed the beginning stage by year 8 at least, but if you’ve ever worked with soil, plants, and livestock, you know the intricacies of these living systems are ones that are learned over a lifetime.

According to the USDA Ag Census, in 2012 there were 522,058 beginning farmers in the US, and 226,670 of those had been farming for five years or less. Though this may sound like a healthy number of new folks entering the field, the census also showed a 20% decrease in the overall number of beginning farmers compared with 2007 (with a 22% decrease in the five year or less category).

There are surely many factors leading to this decrease in beginning farmers across the country, though two of the largest hurdles when it comes to starting a farm are access to capital and land. Many new people entering agriculture are first generation farmers, and therefore don’t have family land or equipment to start out with.

As our food system faces unprecedented droughts in the west, higher flooding rates in the east, and all-around unpredictable weather from year to year, plus an aging farming population where the average age of the principal operator is 58, it’s imperative that we find ways to support beginning farmers, as they are the ones who will not only feed us, but who will be creating new sustainable systems in a changing climate, which in turn will inevitably reshape our national food system.

With that in mind, I wanted to learn more about what kind of financial support there is for beginning farmers. I myself am a beginning farmer, going into the third year of running my business, and am looking at how to finance some major infrastructure improvements. As I began to search for financing options, I found some good news: the number of programs, lenders, and borrowing options out there are many! The closer you look, the more people and places you’ll find that are committed to supporting new farmers and the local food economy. The hard part of it is wading through all the opportunities to find the right one for you.

Financing options can be broken down into a few categories: private contracts, community and state, and federal lending programs. There are also grants to be found in each of these categories.

Private contracts are those between farmers and current land owners, and often come into being when a current land owner is looking for a new farmer to take over his/her business, or for a new farmer to revive an agricultural business on land that is no longer in use. Finding a situation like this take more relationship building and willingness to seek out land owners to present them with a proposal. Many of these organizations, like the “Land Links” help connect farmers seeking land with land owners.

Vermont Land Link

New England Land Link

Center for Rural Affairs – National Land Link and Financing

Beginning Farmers – Finding Land to Farm – Land Link programs by state

Information on Community and State financing programs can often be found through your state’s Cooperative Extension office. In Vermont, UVM Extension runs the New Farmer Project, as well as the Women’s Agricultural Network and the Farm Viability Program, all three of which have educational and technical support for beginning farmers. Local and state credit unions are another, more traditional lending option.

The National Council of State Agricultural Finance Programs has an excellent Directory of State Programs, which is a good place to find more information on loan programs state by state.

Katie Spring researches financing in her yurt “office”

Federal programs through the FSA present still more options for financing, and they offer a a straightforward guide to farm loan programs that details all of the different programs available and helps you figure out exactly where to start.

When you’re ready to start reading through the different types of loans, I recommend getting a hot cup of tea or coffee and a chocolate chip cookie and settling in for a morning or afternoon of gathering information and noting down questions. While there is a wealth of information online, I find it most helpful to get a sense of the programs, write down my questions, and follow up with a real person who can have a more in-depth conversation with me. Reaching out to someone in the Beginning Farmers office at Cooperative Extension can be a good place to start. Don’t forget to have some fun, too! Though it can be a bit daunting to wade through so much information, remember that these all present opportunities, and behind each link there is a real person who wants to see new farms succeed.


Katie Spring owns and operates Good Heart Farmstead in Worcester, VT with her husband Edge and son Waylon. They grow diversified vegetables and meat that they market through a CSA and their mission is “to make fresh, local food accessible to everyone, despite income.” They work with NOFA-VT’s Farm Share program to provide subsidized CSA shares to low-income customers. Katie writes on a variety of topics for her own blog, Wild Spring, and works in Sales at High Mowing during Vermont’s cold winter months.

Growing Partners: The Greening of Detroit

This year we are excited to launch Growing Partners, a series of articles focusing on the farmers, gardeners, seed growers, breeders, vendors, donation recipients and non-profits we work with who are making waves in sustainable agriculture. Together they form a revolution of environmental stewardship and positive change working its way over the global landscape. We’re so invigorated by their trail-blazing work every day, we want to share it with the world–and inspire the food movement leaders of tomorrow to follow in their footsteps.

Neighborhood kids make bird feeders during a Camp Greening session. The Greening of Detroit hosts Camp Greening, an outdoor environmental education program, at city parks throughout the summer months.

To kick off the series, we’re starting with a longtime High Mowing customer and non-profit, The Greening of Detroit. We wanted to let them speak for themselves about what they do and why, so we interviewed their Director of Urban Agriculture, Tepfirah Rushdan to get the lowdown.

HMOS: What is the mission of the Greening of Detroit? What makes it unique?

GD: The Greening of Detroit’s mission is to inspire sustainable growth of a healthy urban community through trees, green spaces, food, education, training and jobs. I think we are unique because all of our three field departments collaborate on various projects that collectively support the mission.  These departments include Green Infrastructure, Workforce Development, and Urban Agriculture. We also are firmly grounded in community while also maintaining a higher vision to support policy and advocacy.

The Greening of Detroit’s farm apprentices learn about transplants and growing methods as they begin their training program at the Detroit Market Garden site.

HMOS: Please tell us about the Greening of Detroit, including location, crops grown, land area in production, and how produce is distributed.

GD: The Greening manages three farm sites in Detroit:

Romanowski Farm Park is a two-acre farm inside of a 26-acre city park in the ethnically diverse southwest neighborhood of Detroit. It features an orchard with five different varieties of fruit in production, a community gardening area, and a butterfly garden.

The Detroit Market garden, a 2.5 acre farm situated in Detroit’s Eastern Market District, is an example of intensive small-scale production site.

Lafayette Greens garden in downtown Detroit. Last season, The Greening hosted more than 100 wellness events and activities on-site. More than 1,300 pounds of chemical-free produce was also grown and donated to community groups.

This farm garden features four hoop houses, a free-standing wash/pack and storage area, and access to Detroit’s premier greenway called the Dequindre Cut.

Lafayette Greens, a 3/4 acre farm and greenspace, is located in the heart of downtown Detroit.  This site was recently donated to the Greening of Detroit by the Compuware Corporation and features a children’s garden, a lavender promenade, trellised hardy kiwi, and a small heirloom apple orchard. Produce is aggregated from all three sites and sold in retail, wholesale, and Community Supported Agriculture (CSA), markets as well as donated to many emergency food centers.

HMOS: What is the relationship between the Greening of Detroit and your local/regional community? What programs do you offer that foster this relationship?

The Greening of Detroit’s nutrition education team teaches students how to grow fresh vegetables and prepare healthy food.

GD: The Greening offers expertise and support to community members looking to create green spaces in their community. We support community efforts to repurpose vacant land in ways that improve quality of life in Detroit neighborhoods. We assist communities in developing neighborhood green plans that may include tree plantings, vacant land treatments, gardens, pocket parks, etc. We hold demonstration gardens with a variety of education classes and community events each year. In addition, we teach both environmental and nutrition education in dozens of schools and housing sites throughout Detroit.

HMOS: How old is the Greening of Detroit? How would you describe its growth/expansion?

GD: The Greening is 25 years old. We began with three employees committed to planting trees in the city. Today we employ between 30 and 40 full-time employees and between 200 and 300 seasonal staff. The city of Detroit has more than 20 square miles of vacant land. Our scope continues to grow as the needs and focus of the city we serve evolves.

HMOS: What are some advantages of the area in which you are located? What are some disadvantages?

GD: Advantages are a robust urban environment (the people). We also have a unique opportunity to transform the city into a cleaner, greener, healthy urban center because of all the vacant land. The disadvantages are the increased pollution in soils and air.

Produce grown at The Greening of Detroit’s farm gardens are sold at farm stands in the city to help fund the organization.

HMOS: What is a major challenge you have faced as an organization, and how did you overcome it?

GD: A major challenge for The Greening of Detroit is funding. This is not unique to The Greening, as all nonprofit organizations struggle with inadequate funding. Many grants are annual or one-time only, and this is disruptive to the continuity of programming. The Greening of Detroit has a complicated funding mix, and is always trying to provide and measure community impact. Unrestricted funding would allow us to strengthen measurement, evaluation and community impact but this type of funding is very difficult to obtain. This is a common challenge for all organizations in the nonprofit sector.

Volunteers assist in the gardens at Lafayette Green garden in downtown Detroit.

HMOS: What resources have been important to your success as an organization? What advice would you give to someone just starting out?

GD: Funding is of course essential to our work. In addition, we hire talented, educated people to champion our mission. Collaboration is also very important to our successes, as well as sweat equity from our volunteers.

HMOS: What High Mowing varieties perform best in your area? (And tell us why if you know). Are there any special techniques you use?

GD: We have had success with all varieties purchased from your catalog, along with a satisfying germination rate. We believe in building and maintaining healthy living soil for success. Our City is extremely diverse in their interests and food choices, so we have chosen to explore the possibility of implementing at least two to five new varieties each year from your catalog.

Students participating in The Greening of Detroit’s Our LAND program plant trees in Detroit’s Rouge Park. After a series of classroom lessons on the environment, students venture outdoors for experiential learning.

HMOS: What are your goals for the future of the Greening of Detroit?

GD: We hope to continue to be a catalyst for environmental stewardship in Detroit, and desire to pass on farming skills to the next generation. We are committed to assisting Detroiters in becoming healthier, self-sufficient, and more knowledgeable about the food options in their community.

A Guide to Seed Starting: Brassicas & Succession Planting (Part 3)

Brassica Seedlings in an HMOS Greenhouse

In our last blog post we covered starting artichoke transplants and “hardening off”, the all-important period of acclimating your seedlings to the outside world. This week we’ll talk brassicas (the family that includes kale, cabbages, kohlrabi, Brussels sprouts, cauliflower and broccoli) and how to make a succession planting plan so that you’ll always have the transplants you need for an abundant, extended harvest.

Brassicas are cold-tolerant plants that should be started soon, depending on your last frost date. (Don’t know your last frost date? Find out yours here). For a last frost date of May 1st, for example, you could begin starting brassicas around March 6th. Because they are frost-tolerant, your brassica seedlings can be planted outside about two weeks before the last frost date in your area.

Starting Seeds

Brassicas germinate best between 65-75ºF, but will germinate at temperatures as low as 50ºF. You may start them on a heat mat if the ambient temperature is cool, just be sure to remove them from the heat mat and place under lights as soon as soon as they germinate. I recommend starting them in fairly large plug trays, such as the 50 cell tray included in our seed starting kit or in 4-packs, but they can also be potted up from smaller cells (like those in a 96-cell tray) once they have their first true leaves. Sow one seed per cell (to avoid wasting seed) unless your space under lights is at a premium, in which case sow two seeds per cell and then snip the weaker of the two with scissors.

Seedlings hardening off in an HMOS coldframe

Be very gentle when potting up these tiny plants, as any small nicks in the stems caused by fingernails or rough handling create an opening for the plants to become diseased. A  butter knife or dowel may be helpful to loosen seedlings from smaller plug trays, especially if they have become root bound. You can find crop-specific seed starting instructions (such as seeding depth, spacing, nutrient requirements and more) on our website here.

Here’s a tip: touch your plants! Gently brushing your hand over the leaves several times a day simulates the wind and helps them grow stronger, sturdier stems. (Just make sure yours hands are reasonably clean first). You can also set up a fan blowing towards the seedlings, which accomplishes the same thing. Keep in mind that the soil in your trays will dry out more rapidly with the increased airflow, so check on them regularly to make sure they aren’t getting dried out. Brassicas do not tolerate heat or drought well, and wilting even a few times can significantly reduce yields.

We discussed hardening off last week, and the same rules apply here. Start giving your plants some time outdoors about 2 weeks before planting, increasing the time they spend outside each day until they spend the whole day outside. Just be sure to bring them back indoors or otherwise protect them in cases of extreme weather.

Frost Tolerance

Continue to keep an eye on the weather for the first few weeks after your seedlings have been planted out, and cover with row cover or low tunnels in the event of a hard frost or hail. In general brassicas will tolerate a light frost, when temperatures dip between 28-33ºF for a few hours. Young plants are more vulnerable than mature ones, however, and must be covered to survive a hard frost, when temperatures fall below 28ºF for more than 2-3 hours. Hard frosts usually occur on spring nights with clear skies and calm conditions.

Making a Succession Planting Plan

Brassicas are a great example of a crop that you can succession plant repeatedly throughout the season to extend the harvest as long as possible. They thrive in the cool conditions of fall as well as in the spring, and can even be overwintered in many climates. Creating a succession planting plan will help ensure that you always have transplants ready just when you need them.

To make a plan, use a grid or spreadsheet to conceptualize how your garden space can be maximized over time. First determine a way to divide up your garden, such as by bed and row, and give each a name to stay organized. Write the name of each bed in the left-most column of your grid. Then use the months of the year as the headings for each column starting from left to right. To figure out how long a crop will remain in each bed, you would need to first determine the days to maturity for that variety (listed on the packet) and then add the time you’ll be harvesting from the crop to figure out how long to dedicate that space to it. But that information varies by variety, region and conditions—so let’s just stick with the broad strokes:

Short Season Crops take 30-50 days to reach maturity and are harvested over 1-3 weeks. Allow 1.5 months for these crops: Cilantro, Fennel, Salad Greens, Baby Greens, Head Lettuces and Radishes

Mid Season Crops take about 40-60 days and are harvested over 1-3 weeks. Allow 2-3 months for these crops: Basil, Beans, Beets, broccoli, Cabbage, Carrots, Cauliflower, Cucumbers, Greens (Full Sized), Kohlrabi, Okra, Peas, Potatoes, Scallions, Spinach, Summer Squash and Turnips

Long Season Crops take 55+ days to reach maturity and are harvested over a 1-3 month window. Allow 3-4 months for these crops: Artichokes, Beans, Brussels Sprouts, Celery, Chard (Full Sized), Collards, Corn, Eggplant, Kale, Melons, Onions, Peppers, Pumpkins, Tomatoes, Watermelon and Winter Squash

Lay out your crops in the grid according to how long they’ll spend in the garden. Use our Vegetable Planting Guide to determine how early to start transplanted crops. Then mark your calendar with the dates you need to start transplants in order to plant on time according to your plan. Here’s an example based on a northern garden:

A Guide to Starting Seeds: Artichokes & Acclimation (Part 2)

If you read our article from last week, you already learned about gathering your seed starting materials, including lights, soil, containers and more. You (hopefully) figured out your last frost date, and used it to determine when to start your first transplants (onions and leeks). This week we’ll talk about starting your next crop, artichokes, and how to “harden off” all of your seedlings in preparation for outdoor planting.

Artichoke Seedlings

Artichokes are a perennial crop that can be grown as an annual in areas with cold winters. They should be started 8-10 weeks before planting outdoors—so if, for example, your last frost date is May 1st, they should be started between the middle and end of February. In order to produce flowers (artichokes), they need to be convinced that they are in their second year of growth. In other words, they need to be “vernalized”, or exposed to cold, to make them think they’ve experienced winter. Our variety, Tavor, requires less vernalization time than others, but it is still essential to produce artichokes.

Germination & Vernalization

Here’s a tip for success: before starting your artichoke seeds, put them in an airtight container in the refrigerator with a small amount of slightly damp peat moss. The cool, damp conditions will help convince your seeds that it’s springtime, and result in better, more even germination. Start artichokes according to our instructions (under the Growing Info tab), keeping the plants between 60-70ºF until two weeks before your planting date. At that point, move the plants to a cold frame or other cool, protected location. The goal is for them to experience some stress, with temperatures below 50ºF but above freezing for ten days. If the weather threatens to dip below freezing in that period, move them indoors until the frost danger has passed.

Bed Prep

Once you’ve moved your artichokes outside for vernalization, it’s time to prep your artichoke bed. Loosen the soil with a garden fork and incorporate compost, then dig a 6” deep trench in each row and line it with compost. Space plants 4-6’ apart over these trenches, in rows 7’ apart. After planting, keep an eye on the weather and cover your plants with row cover if frost or hail threatens.

Growing Tips

Anyone who’s grown artichokes knows that they’re a bit particular—they like cool (but not cold) winters, warm (but not very hot) summers, and moist, fertile soils. A good rule of thumb to make them happy all the time? Compost and mulch once a month, and provide a little shade from the hot afternoon sun so they don’t get too dry. With a little care and a little luck, you’ll be harvesting 7-8 buds per plant. And yes, you can grow artichokes in containers, but they’ll need to be BIG—ideally the size of a whiskey barrel or larger—and always kept moist for bud development. They make great ornamentals, and look beautiful in giant mixed containers with flowers like Sea Shells Blend Cosmos and our trailing Nasturtium Blend. The nasturtiums will help cover the surface soil in the container, keeping it cool and moist even in bright sun. And of course, if you don’t harvest the artichokes they’ll make giant purple thistle-like flowers that will knock your socks off.

A coldframe, like this HMOS low tunnel, is a great place to harden off seedlings

Hardening Off is just what it sounds like—preparing your coddled transplants for the harsh world outdoors. (Note: this is for your other transplants, not artichokes.) Hardening off is simple to do, requiring just a little of your time and attention, but it makes a huge difference in terms of plant health and reducing “transplant shock”. About two weeks before your planting date, move your transplants outdoors to an area protected from strong wind. Leave them out for just an hour or two the first day, especially if it’s sunny or windy, and then bring them back inside. The next day increase the time they spend outside to 3-4 hours, and so on each day until they spend pretty much the whole day (and night) outside. The key to hardening off is to be aware of the weather and make sure your still-tender plants don’t get left outside in strong winds or torrential downpours before they’re really ready for them. You’ll notice as the days pass that the plants will become visibly sturdier, growing thicker stems and producing more protective waxes on their leaves.

When it’s time to plant, the best time is on an overcast day, just before it rains, or late in the afternoon on a sunny day. If your plants are properly hardened off, planted at a suitable time and watered in, they should acclimate beautifully to the outside world.

Stay tuned! Next week we’ll look at starting brassicas and how to create a succession planting plan, so that you’ll always have the transplants you need for an abundant, extended harvest.

Hot Potatoes – for Every Purpose

Comparing Potatoes in High Mowing Trials

Here at High Mowing, we LOVE potatoes. They always appear at our monthly potluck lunches, they’re endlessly versatile in the kitchen, and they store beautifully–an important feature in a state where the growing season is a mere 120 days (in a good year!) They make a great early crop for farmer’s markets, and come in such a wonderful range of colors, flavors and uses these days that just about everyone can pick a favorite. Everyone…except Paul.

Paul Betz with Potatoes

Paul Betz has earned the affectionate nickname “Potato Man” here at HMOS, and is without a doubt our resident expert. Normally, though he is a Commercial Grower Sales Rep and an organic farmer at High Ledge Farm in Woodbury, VT. He grows many varieties on his farm each season, conducts trials, and always knows what to recommend at the end of the day–but of course, as a true potato connoisseur, what he recommends will depend entirely on what you want to do with your potatoes. So next we’ll introduce all of our new potato varieties, and include Paul’s thoughts on each.


Early Season

Purple Viking Potato

Purple Viking

Paul: “Purple Vikings make beautiful new potatoes and are visually exciting at all stages. If allowed to grow to full size, they also store well – a very versatile potato with great flavor.”

Outstanding yields of spectacular deep purple potatoes with rich flavor – a winner in our taste tests! Bright white flesh is moist and firm, adaptable for many types of cooking. Vibrant purple skins are flecked with pink for an eye-catching early market offering. Compact plants; good Scab resistance. Compact habit • For fresh market. (Solanum tuberosum)

Disease Resistance: Scab


Mid Season

Yukon Gem

Yukon Gem

Paul: “Yukon Gem is a much-improved version of Yukon Gold, offering all the same great qualities as Yukon Gold but with better disease resistance and significantly higher yields.”

This mid-season variety features bright gold skin, pink hued eyes, yellow flesh, and the same delicious flavor as its parent Yukon Gold. Resistance to blight and scab make this a fantastic potato! Round to oval tubers mature about 10 day later and are significantly higher yielding, especially in wet conditions. (Solanum tuberosum)

Red Chieftain

Red Chieftain

Paul: “Red Chieftain is awesome for storage and is super uniform – much more so than Red Norland – but it matures a bit later than Norland, so I recommend planting both.”

Large, oblong red tubers with very good flavor and storage potential. Thin coppery-red skins and shallow eyes make this a beauty on the table or at market. Delicious boiled; a treat as a new potato. Superior flavor to Dark Red Norland with better storage potential. Very resistant to Scab. Stores well. (Solanum tuberosum)

Disease Resistance: Scab


Late Season



Paul: “Elba is one of my favorites – it’s incredible mashed, standing up in amazing fluffy white peaks with delicious flavor. It’s also great for storage.”

High yields of large potatoes with buff skin and delicious white flesh. Easy to grow with good disease resistance, especially to fungal blights. Ideal for baking and salads; excellent storage potential. Stores well. (Solanum tuberosum)

Disease Resistance: Scab

UPDATE: Our potatoes ship by April 15th, but we recommend ordering as soon as possible – varieties sell out quickly. Check out all of our potato varieties here and learn how to green-sprout potatoes in Paul’s article from last year.
