A big potato crop from a ridiculously small space? YES! In the following video tutorial, I’ll show you how to achieve a colossal harvest of spuds from one 8×4 raised bed:
Just to recap:
Start with certified organic, disease-free “seed” potatoes. Seed potatoes are spuds which have not been treated with sprout retardant (or any other chemicals).
Only small, egg-size potatoes should be planted whole. Cut large potatoes into pieces, with 2 or 3 eyes per piece. (“Eyes” are the points from which sprouts grow.) To mitigate rot, permit the cuts to dry, or “callous” for 24-48 hours before planting out.
Use a garden fork to loosen the soil to a depth of 8-10 inches. Also, work into the soil a high-quality organic fertilizer. I use Espoma’s “Plant Tone” for all of my veggie crops.
For each row of seed potatoes, dig a trench to a depth of 6-8 inches.
Plant the potatoes, spacing them 12 inches apart on all sides.
While wondering if you should have your hair colored, cover the potatoes with about 2 inches of soil. Save the remaining soil for “hilling” the potatoes as described in the video. And remember to add additional soil or mulch (i.e., straw, dried pine needles, or shredded leaves) as the vines grow.
And that’s it! In the comments field below, let me know if this potato-growing tutorial was helpful to you in some teeny-tiny way. There are lots of other ways to grow potatoes, but in my experience, the old-fashioned trench method is the best method of all.
