Never did sweet potatoes but have done reg ones with great sucess.
Peruvian Blue- Blue skin & flesh-awesome and keep VERY well
Red Norlands-red skin white flesh-great taste but do not keep as long
Katahdin & green mountain- (white flesh)decent flavor-keep well
Adirondack Red-Red skin & pink/white marble flesh Very good flavor & yeild but did not keep long
Last year was the first year growing the Blues. I did not expect them to yield as well as they did nor keep as long as the whites but they did! Also tried the Adirondack Reds for the first time last year and was VERY pleased with the flavor. Their storage time seemed very short however...so we made sure to use these first (it was not a hard thing to do
)
I throw right in the ground & hill them....mulching seems like to much work for me!
Good luck and have fun growing.....and make sure you taste test them right out of the ground before their sugars turn to starch.....SO DAMN GOOOOOOOOOD! No butter or sour cream needed!
