Pseudo Straw Bale Potato Gardening

Last year we grew 9 different varieties of Irish Potatoes in our garden. We also grew sunchokes and sweet potatoes, and while there’s nothing quite like a fried potato, this year we decided to focus less on Irish potatoes, and more on other tuber crops.

Still, we figured we would try a low risk garden experiment this season by planting our seed potatoes in raised straw beds. Some advantages to this approach are that as the potatoes grow, instead of hilling them up with soil, we simply add more and more straw to cover the stems and encourage more tuber development. Because the potatoes grow in straw instead of soil, harvesting is easier and the tubers come out cleaner.

Last fall, after our homestead wedding, where we used straw bales benches, we strategically stacked the leftover bales in our garden area along the same contour layout of our raised beds. The thought was to simultaneously kill off the weeds and grasses underneath the bales and prepare the soil for new beds while conditioning the bales for planting.

We ended up going in a different direction though when spring came around, deciding to instead raise potatoes above the ground, and constantly add layers of straw to the growing stems.

First, I had to move the strawbales into a big pile next to the planting area. This exposed the nicely prepared and weed free “bed”. Hopefully this new pile will smother any weeds under it and allow us to expand this experiment in a few weeks.   I then added a sprinkling of organic fertilizers and compost. I used a mixture of bone, blood, alfalfa, kelp and greensand, and then covered it with a nice layer of decomposing straw.

This is when I added the seed potatoes. I laid them out in multiple staggered rows, about 1 foot apart. I then went through and liberally gave each seed potato a handful of compost, and another pinch of fertilizer.

On top of this went a big layer of straw, probably 4-6 inches high, and then another light dusting of compost of fertilizer.

the compost and organic fertilizer should help break down the straw into humus and keep our potatoes healthy

I am fertilizing this patch heavier than I would normally because the straw is high in carbon, and will require some extra nitrogen to fully breakdown. The end result should be a beautifully composted soil, and a nice harvest of potatoes as a bonus.

This kind of planting will need a little extra attention in the beginning, especially during dry spells, because the upper layers of straw have a tendency to dry out. Once the straw is 18 or so inches high I don’t think it will be problem anymore. If the potatoes seem to do okay, we may just try some sweet potatoes this way as well. I can’t believe that it’s almost time to start sweet potatoes slips again!

First Potato Harvest Taste Test of 2014

The other day we harvested the first of our 2014 potato crop. We planted 9 different types of seed potatoes, and we figured it was time to check on 2 of our early varieties, Cobbler and Early Ohio. The vines still had some life to them, but we decided to check on their progress anyway and dug up 1 plant of each. We jumped the gun a bit, but between the 2 plants, there was enough for a nice side dish of boiled new potatoes.

Early Ohio potatoes on the left, and Cobbler on the right.

The Cobblers were noticeably larger, and the plants had just begun to die back, whereas the Early Ohio’s were tiny, and they were many more pea sized potatoes that were still in the process of growing. We harvested some of the bigger tubers from each plant, and then replanted and watered in the rest to give the tiny tubers some more time. All told, we got 3/16 of a pound of Early Ohio, and 5/8 of a pound of Cobblers.

After a quick rinse and scrub, we cut the cobblers into pieces about the size of the tiny Early Ohio potatoes, and boiled them in salty water. Fresh potatoes cook much quicker than store bought ones and in almost no time we began our first of many potato taste trials. The two early white potatoes were similar in flavor and texture but still different. I enjoyed the sharpness of the Early Ohio, while Emma enjoyed the more potatoey flavor of the cobbler which is better suited to boiling and steaming.

Because these early potatoes still needed more time, I fertilized all of the potatoes today with a mix of bone meal, alfalfa meal, and greensand. I for one can’t wait until we have all 9 varieties harvested, and can review and compare them all at the same time!

Unique and Rare Potato Varieties for 2014

The seed potatoes that we were waiting on arrived the other day, and within 48 hours we had them in the garden. In total, we planted 9 varieties and we’ll buy 1 more type at the supply store soon to make 10.

We tried to keep the number of plants relatively even, so that we can compare yields among varieties, in addition to flavor, store-ability, and disease resistance. We did this by cutting larger seed potato pieces into smaller pieces, but making sure that each piece still had at least 1 nice eye to grow from. Seed pieces the size of an egg, a chicken egg that is, we planted whole. We ended up planting 176 seed potato pieces, which in a perfect word would make 176 plants. We’ll see….

Most of the varieties we planted are either rare heirloom potato varieties, or delicious gourmet varieties. Here’s a brief rundown on what went in the ground.

Of the early potatoes, we planted Early Ohio, an heirloom from Vermont grown since 1871 with a nutty flavor, and Cobbler, another heirloom from the 1800’s that is said to have been discovered by an Irish shoe maker.

We planted a few mid-season varieties, including Carola, a German potato with a creamy yellow flesh, Kennebec, a popular and high yielding variety grown all over the country, and Purple Majesty, a beautiful purple skinned and fleshed variety high in anthocyanins, an antioxidant found in blueberries, currants, and aronia.

The late season varieties were Bintje, a Dutch potato from 1910, German Butterball, a delicious yellow fleshed gourmet type, Katahdin, a high yielding and long keeping variety from 1932, and Red Pontiac, the red potato we grew last year that knocked our socks off and made us potato snobs.

We also planted a fingerling variety named Ozette. This potato has the best backstory of all the potatoes we planted this year. The Ozette potato, unlike every other potato grown in the US came directly from South America by Spanish Explorers in 1791. They brought it with them form the Andes, and it was planted in a small garden outside of a fort in the Pacific Northwest. When the Spaniards abandoned the fort, the Native Makah people found the Ozette Fingerling potato, and have planted, and relied on it as part of their diet every year since.

All other potatoes were first taken to Europe, where the Irish, Prussians, and the rest of the Continent developed new varieties, and then brought these varieties to North America when they immigrated centuries later. The Ozette potato is said to be one of the tastiest potatoes around, and having tasted more than a few Peruvian potatoes myself, I can’t wait.

Ready and Waiting for Potatoes

Spring has arrived and many of our garden crops are either in the ground, or started in trays awaiting their turn in our raised beds. Many, but not all. We are a little behind on one cool weather crop, and it’s one of our favorites… the potato.

Last year’s potato crop, harvested the day Jason proposed to Emma.

This year we are planting at least 9 different potato varieties in our garden, about 2.5 pounds of seed potatoes for each. The reason we haven’t planted them yet, is that we haven’t received them. Because we are planting such a diversity, and many of the types are rare or heritage and heirloom varieties of potatoes, we ordered from an online supplier. They should come any week now, and we can’t wait to get them in the ground.

Last year, we did very well growing red Pontiac potatoes, which lasted well into winter and were delicious baked with sausages, peppers, and onions. This year I’m excited to try out the Ozette fingerling, a variety that ended up in the U.S. hundreds of years ago after a ship washed ashore on the way back from Peru, the birthplace of the potato.

Potatoes grow best in cool weather, and because they are in the nightshade family, you should take care not to plant them where you grew tomatoes, peppers, or eggplants the year before. We are actually digging a whole new series of hugel beds this spring to house our potatoes. Sepp Holzer often plants his new hugelkulture mounds with potatoes as they are light nitrogen feeders, and give the wood core some time to begin the decomposition process.

After our seed potatoes arrive, we’ll try and get them going as soon as we can, because once you’ve experienced homegrown potatoes, it changes you. It turns you into a potato snob, and makes it impossible to eat store bought potatoes ever again!
