My first ever harvest of Porto Rico sweet potatoes was small but will be plenty for us. Lesson learned. Till deeper or hill more soil around the plants. I don’t think I dug the spot where I put the slips deep enough. The soil was like cement a few inches down. It has been very dry but I still think I probably didn’t till deep enough. As is evidenced by the photo they are on the small side. I didn’t weigh them but am happy with the haul for the most part. I am ‘curing’ them on the back porch as they are supposed to store much better after curing.
I think next year I will grow them again but may put them in a couple of half barrels where the soil is looser and will be easier to dig. Porto Ricos don’t vine nearly as long as some varieties, probably getting about 4-5 feet long. They might look nice spilling over the sides of the planter with some annuals mixed in for color.
