Sweet Potato Harvest

We harvested 89 pounds of sweet potatoes yesterday. That’s not a record, but it’s well above our normal yield, and we’re happy with the results. Our average sweet potato yield is about 80 pounds per bed.  We grow a variety named Jewel (sometimes spelled Jewell).  We’ve been growing Jewel from our own starts for over 10 years and we find it excellent for both yield and long-term storage, and they taste great, too!

The potatoes were grown in this very clayey bed.

For harvesting, we first removed all the vines and the black plastic sheet which covered the bed and acted as a solar collector to heat up the soil.

The forecast is for warm temperatures for the next ten days, but I had to harvest now because I noticed some vole damage on one of the potatoes when I checked under the plastic, two days ago. Any increase in yields we might have gotten for leaving them in the ground longer could have been easily offset by damage from these little varmints.

Fortunately the damage was limited to two plants and was not significant. I found a nest under the plastic, but no voles.

We trimmed up the roots before we weighed them and wheeled them to the house for a two week curing on the kitchen table.

After two weeks in the kitchen, we’ll wrap the larger potatoes in newspaper and store them in the basement. We will be able to enjoy our harvest all year long.
