5 Ways to Easily Grow Potatoes at Home

Some months ago, we published some Reasons You Should Start Eating Potato, you may like to view that first before you continue with the post.

1. Hilled Rows
Dig straight, shallow trenches, two to three feet apart, in prepared soil. Plant seed potatoes 12 inches apart and cover with about 3 inches of soil. When the shoots reach 10 to 12 inches tall, use a hoe or shovel to scoop soil from between rows and mound it against the plants, burying the stems halfway. Repeat as needed through the growing season to keep the tubers covered.

The benefit of this growing method is that it is not done by container gardening, so there is nothing to buy or build and no soil to transport. This is a simple, inexpensive, and proven method that farmers have used for millennia. It is practical for large-scale plantings, also. However, the yield may be limited by the quality of the soil. In places where the soil is badly compacted or low in organic matter, an above-ground technique might work better.

2. Straw Mulch
Place seed potatoes on the surface of prepared soil, following the spacing specified for hilled rows, and cover them with three to four inches of loose, seed-free straw. Mound more straw around the stems as they grow, eventually creating a layer of one foot or more in depth.

The benefit of this method is that the thick mulch conserves soil moisture and smothers weeds. Harvest is effortless with no digging, and this method is suggested as a way to thwart Colorado potato beetle. However, our yield in the test plot was slightly less than in the hilled row and field mice have been known to use the cover of straw to consume the crop.

3. Raised Bed
Loosen the soil in the bottom of a half-filled raised bed. Space seed potatoes about 12 inches apart in all directions and bury them 3 inches deep. As the potatoes grow, add more soil until the bed is filled. If possible, simplify harvest by removing the sides. This method yielded the largest harvest in my trials, and the potatoes were uniformly large in size. Raised beds are a good choice where the garden soil is heavy and poorly drained. The downside: the soil to fill the bed has to come from somewhere—and it takes a lot.

4. Grow Bag
Commercial growing bags are constructed of heavy, dense polypropylene. Put a few inches of a soil-compost mixture in the bottom of a bag, then plant three or four seed potato pieces and cover with three inches of soil. Continue adding soil as the plants grow until the bag is filled. To harvest, turn the bag on its side and dump out the contents.

Grow Bags can be placed on patios or driveways or used where garden soil is of inferior quality. The bags should last for several growing seasons. Their dark color captures solar heat to speed early growth. Harvest is simple, and the yield can be impressive, considering the small space each bag occupies. However, this can be a pricy technique. The brand of bag I used costs $12.95.

5. Garbage Bag
Plant a large plastic garbage bag following the instructions for a grow bag, punching a few holes through the plastic for drainage. Roll the top edge of the bag to help it stay upright, otherwise the bag is prone to sag and spill soil. To harvest, rip the bag and dump out the contents.

Like the grow bags, a garbage bag can be employed where in-ground growing is not an option. Black bags capture solar heat to speed early growth. Aesthetically, however, this is the least appealing choice. Our yield was meager, perhaps because the thin plastic allowed the soil to heat up too much, limiting tuber formations.
