This is my third time growing sweet potatoes.
- In 2010 I grew a 1 x 2 ft square of them in a deep new raised bed. I raised 8 pounds of sweet potatoes in that loose, rich soil.
- In 2011 I grew an 8 x 2 ft row of them in a deep old raised bed. My yield was 2 or 3 pounds of potatoes in that hard, dry, clay soil.
This year I am trying a hilled approach.
This is just bagged dirt, mixed with what I already had in the bed, and amended with some Dr. Earth fertilizer. My hope is that if I keep these hills moist, the soil will remain loose and friable enough for the sweet potatoes to go bonkers and grow well for me.
I shouldn’t mix experiments, but another thing I’m trying that is different this year is that I didn’t cut the sweet potato slips off the mother spud…I just pulled the whole piece from the jar where I sprouted it and stuck it in the dirt.
There are six hopeful sweet potato plants in these 3 hills. The dirt under the hills was worked loose down to 8 or 10 inches. As the vines grow and sprawl over this bed, I’ll let them root wherever they want. Anywhere a vine roots, potatoes start to grow down from there.
My wife says it looks like I buried somebody here.
