I spent the week harvesting sweet potatoes, one variety a day. Georgia Jets and Purple are the varieties that grow fastest. I checked under their vines a couple of weeks ago and found they were sizing up nicely. I removed a few Purples which showed me they were big enough that there would be no advantage in delaying harvest and lots of potential for rodent damage if the sweet potatoes were not harvested soon.

My sweet potato bed was 4’x13′ with 2 rows of plants spaced 1′ apart.  Here are the harvest numbers. Most varieties did better than last year, with the exception of Laceleaf which is even worse than last year.

 2014 Planted 6/30 # yield per
Variety Harvest pounds plants plant
Frazier White 7.9 4 2.0
Georgia Jets 14.5 3 4.8
Korean Purple 8.8  4 2.2
Laceleaf 4.0 4 1.0
Purple 19.0  4 4.8
Beauregard                   4.8        1         4.8
Planting total 58.9 20

In mid-June I got more plants, extras that were not needed in the gardens at Locust Grove. Three Purple slips went into an empty spot along my fence. Sweet potato vines are aggressive. My neighbor had onions on the other side of the fence but I managed to keep the vines on my side until he pulled his onions. The vines were 3′ into his garden when I started harvesting this morning.

The three plants from the mid-June planting yielded 19.4 pounds or 6.3 pounds per plant. Phenomenal for a cool-ish summer in the northeast USA.

This is what I mean by an ugly sweet potato. It is nicely sized and shaped, but split and cracked plus it has surface damage cause by an animal or insect. All but one of my Georgia Jets have the same damage. They won’t store well.

All in all, 2014 was an excellent year for sweet potatoes.
