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.

 

2015 Sweet Potato Harvest

Over Four Pounds

Over Four Pounds

As the garden season winds down, we’re happy to report that we’ve had another great sweet potato harvest.  I like to remind people that it’s easy to grow sweet potatoes even up north, here in Wisconsin.

Frost and Beetle Damage

We already had a light frost  and the leaves were pretty moth eaten from Japanese beetles.  I decided not to wait longer to get them out of the ground.

I stacked all the vines up in the center of the bed so I could easily prune them off using pruning lopers.

Of the seventeen plants, most were quite robust, but three or four were on the puny side.

Drying on the Kitchen Table

Sweet potatoes need to be cured or allowed to dry out at a relatively warm temperature before being put into storage.  Here’s most of the harvest curing on the kitchen table.

Wrapped and Stored

Wrapped and Stored

After a two week curing, we wrap the larger potatoes in newspaper and store them in our heated basement.  They’ll keep a year in storage and maybe even a little longer.  Left too long, they’ll start to sprout, which is okay, because the sprouts are a good source for sweet potato starts to plant again next season.

We grow a variety named Jewel or Jewell.  It has consistently delivered good yields.  It produces a lot of nice fat potatoes with very few stringy unusable roots.  We harvested about 74 pounds of sweet potatoes.  Not our biggest ever harvest from a single bed, but still pretty good.
