do you do any thing with sweet potatoes when you harvest them ? I was told you need to cure them after you pick them. If so how do you do this and do you have to cure them if you are canning them ? Thanks for any info .
If you cure them, they give up a percentage of water which makes them much sweeter than fresh dug. There are a lot of complicated procedures for curing. But I just do like past generations did. Spread out on the floor of a dry shed ( we use to use the corn house in my youth) for two three weeks while the weather is still warm. Just cant't let them get below 50 degrees or crowd ( no more than 3-4 layers) them when they are sweating. For canning it probably does not make that much difference, but properly cured they will keep through spring in the pantry or a spare heated room.
How do you know WHEN sweet potatoes are ready to be harvested..??.. I stuck some 'shoots' off a sweet potato that I was going to throw out...just as an experiment...hoping for some potatoes for Thanksgiving.
I've got some beautiful vines all over the place...but not sure that there are any new potatoes growing anywhere. ??
In most areas, they are dug just before the first expected frost and cured during Indian summer. Some folks wait till frost, pull the vines to prevent the blackening of the vine to drain back into the potaoes and dig at thier leisure. In warmer climates like here in Georgia, I start digging about the first of October as they do not grow much after the fall equinox.
Certainly work for storage as long as it does get below 50 degrees. probably work for curing as long as the humidity is low. Yes the potatoes are storage roots which should be concentrated at the base of the plant. Smaller potatoes will of course form wherever the plants sends roots into the ground.
