Grow Biointensive is an organic agricultural system that focuses on attaining greatest yields from a small garden area.\u00a0The process involves double-digging beds, feeding the soil with compost, and planting closely to conserve spacing and create a microclimate. This method uses less garden space and eliminates the labor of hilling your potatoes.<\/p>\n

\"Planting<\/p>\n

My first year of growing potatoes, I used the traditional trench method<\/a>. This involves digging trenches two feet apart, mounding the soil in between the trenches, and using this soil to hill the potato plants as they grow. Although the crop was successful, I didn\u2019t like the extra labor involved in hilling, the unkempt and messy appearance of the plot, and the wasted space in between the rows.<\/p>\n

While I was growing my first batch of potatoes back in 2010, a fellow blogger, Laura\u00a0was experimenting with John Jeavons\u2019 Grow Biointensive potato planting method.<\/p>\n

The Grow Biointensive program is made up of eight principles to grow healthy food naturally and care for the soil at the same time. The eight principles are: deep soil preparation, composting, intensive planting, companion planting, carbon farming, calorie farming, open-pollinated seeds, and whole system method.

Planting potatoes the Grow Biointensive way involves double-dug beds, feeding the soil with compost, and planting closely to conserve spacing and create a microclimate. The potato seeds are planted on top of the fluffed up soil, 9-inches apart and about 9-inches deep from the soil surface. The rows are planted in an offset, or diamond spacing. The closer spacing helps maximize space and creates a microclimate that shades out weeds and reduces moisture loss. The deep, 9-inch planting eliminates the need to hill your potatoes.<\/p>\n

I was intrigued by this method, especially since Laura\u2019s experiment was such a success. I did some further research and decided to try it the following year. I was so thrilled that my experiment worked even though I didn\u2019t follow the instructions exactly! I had an abundant potato harvest that year providing plenty of potatoes for winter food storage.<\/p>\n

I have modified the method a little over the years. Since I don\u2019t walk on my garden beds, there is no need to double dig each year. Once your soil is loose and healthy, adding some finished compost and organic amendments at planting time is all that you will need to do. The instructions below assume you have never double dug your gardening beds.<\/p>\n\n

How to Plant Potatoes the Biointensive Way:<\/h2>\n

Step 1: Make a measuring board:<\/h3>\n

It is helpful to use a measuring board to place across your gardening bed to mark the spacing of your planting holes. I use a 2×4 scrap board and mark out 9-inch intervals on one side with a marker, then turn the board over and mark out 9-inch intervals on the other side but off set from the first side. So all I have to do is flip the board over to measure the next row creating a diamond pattern.<\/p>\n

\"Planting<\/p>\n

Step 2: Double dig and plant your potato bed:<\/h3>\n

You will be double digging and planting your potato seeds at the same time. The first step is digging a row about 12-inches deep. The soil from this first row is placed into a wheelbarrow and set aside. Once the row is dug, add some finished compost and an organic fertilizer to the trench. Use a digging fork to mix in the amendments and loosen the soil in the trench to a depth of another 12 inches. This will allow oxygen into the soil and helps the roots to penetrate easier.<\/p>\n

Step 3: Plant your seed potatoes:<\/h3>\n

Place your measuring board across the bed and mark out your planting holes. You are aiming to plant your seed about 9-inches below the soil surface. Since the soil is fluffed up, you may need to dig down into the soil to be sure your planting holes are 9-inches deep. You can use a hand trowel or even a large bulb planter. Place your potato seeds into the holes along the trench with the sprouts facing up. Once the first row is planted, you will be covering it with the soil from the next row.<\/p>\n

\"Planting<\/p>\n

Step 4: Plant your next row:<\/h3>\n

Measure the next row 9-inches away from the first and begin digging your second row about 12-inches deep. As you dig, use the soil from the second row to cover the first. Add your amendments, mix in and loosen the soil another 12-inches with a digging fork. Flip your planting board over and plot out your planting holes. Remember, these should be spaced offset from the previous row.\u00a0Continue in the same way until you have planted all your potato seed. Once you have reached the final row, cover the trench with the reserved soil from the wheelbarrow.<\/p>\n

Step 5: Mulch the potato bed:<\/h3>\n

Once the bed is planted, string soaker hoses (if using) along the rows and water well. Mulch the bed heavily to help retain moisture, reduce weeds, and keep the light from reaching any potatoes that reach the soil surface. I like using straw as mulch, but also use shredded leaves if straw isn\u2019t available. Your potato plants should emerge from the soil in about two weeks. It may take longer if the soil is still cold.<\/p>\n

\"Planting<\/p>\n

Step 6: Add poles and twine for support:<\/h3>\n

Add four poles to the corners of your potato bed and string some twine to provide support as the potato plants grow. In the book, The Sustainable Vegetable Garden<\/a>, John Jeavons suggests that staking potatoes helps the plants to remain upright creating a microclimate to keep the plants and soil cooler. This will also keep the plants from flopping into the walking paths.<\/p>\n

\"Planting<\/p>\n

Step 7: Harvest your potatoes:<\/h3>\n

Baby potatoes are delicious. Once the potato plants bloom, you can begin harvesting potatoes as needed for meals. Dig carefully beneath the soil and pull out what you need. Try not to damage too many roots so the plant can continue growing. If you are growing potatoes for storage, allow the tubers to remain in the ground to mature fully.<\/p>\n

Planting potatoes the Grow Biointensive way has served me well over the past few years so I haven\u2019t tried too many different ways to grow potatoes, but thankfully many other bloggers have, and they allowed me to share their experiences.
