I am still waiting on some potatoes to arrive in spring. I thought I had all I needed. Then I learned more about the purple sweet potato. So I started looking. I was really hoping to find purple sweet potato tubers. but had to settle for slips from Bakers Creek. . They say April 1 or so for shipping. So I am recording my order here. I do this for my records. And you may learn from my notes. I also want some other things from cultivariable.
Notes: Leaves are also edible as with other variety sweet potatoes
Sweet potatoes of all varieties are high in vitamin A, vitamin C and manganese. They are also a good source of copper, dietary fiber, vitamin B6, potassium and iron. The antioxidant known as anthocyanin is the pigment which is responsible for the brilliant purple color of the flesh. It is the same pigment that gives blueberries, red grapes and red cabbage their color.5 Blueberries are well known for their high antioxidant levels, however, the Okinawan sweet potato actually has 150 percent more antioxidants than blueberries.6 Antioxidants help to guard against cardiovascular disease and cancer.
Growing sweet potatoesThis is my first time ordering slips.
But, I have a jar with water. 1 potato cut in half. I will pull slips off when 7-10 inches tall.If they have some roots. I will place them in some compost.
I have another sweet potato laying on top of good compost. Then covered with peat moss. Removing slips when ready to plant or at 7-10inches tall.
Sweet potatoes mature in 90 to 170 days and are extremely frost sensitive. Plant in full sun 3 to 4 weeks after the last frost when the soil has warmed.
*GROUND TEMPERATURES NEED TO BE AT LEAST 65 DEGREES- HOWEVER A HIGHER TEMPERATURE IS BETTER AND WILL MAKE FOR A MORE BOUNTIFUL CROP. AT NIGHT THE TEMPERATURE SHOULD BE ABOVE 50 DEGREES. I have also read, planted late in the heat of July may produce better results than planting in May if temperatures are not hot enough.
Make holes 6 inches deep and 12 inches apart. Bury slips up to the top leaves, press the soil down gently but firmly, and water well.
Do not use nitrogen-rich fertilizers they will produce lush vines and stunted tubers. So just a good aged compost will work fine.
I have read (CHILLED PLANTS WILL NOT YIELD 100%.)
"Northern States must use black plastic, cover bedded rows 2-3 weeks before plants arrive." So I am going to try this. With our weather last summer we were in the 70's till August. So this would have delayed tubers.
They also need lots of water. Which will not be an issue in Missouri, if we have another summer of rain.
