What makes sweet potato plants form tubers?
My plants have been damaged by hail, but I think will continue to grow. Do they flower before they produce tubers? Or is it light or temperature related?

Sweet potatoes are true roots not tubers. As the plant ages it uses the roots roots as storage. They usually begin storing when when about two months old and will continue until the plant dies. They are a perennial and will live until killed by frost. It takes about 3 months on average to form usable sweet potatoes. Many varieties never flower and for those that do has no effect on root development. They are tropical plants in the morning glory family and grow fastest at high temps and humidity.

Thank you! That helps.
We are having higher temperatures, so unless there is early frost I still have hope!

And I have a plan for the humidity for next year:
I will plant them in large Rubbermaid bins, but with drainage holes.
I will place these under the glass topped patio table.
Then I will use tape to make plastic walls around the table
? plastic shower curtains or the like.
If cold spells threaten----I can hang a shop light under the table
to drive off a few degrees of frost if needed.
I could place large pails of water under there too to act as a heat sink.

If you are talking about South Carolina, You can set plants from mid-April to mid June and expect a harvest. Southerners are not pressed for time like folks in the North.

This year, I thought that I would try growing sweet potato slips.
These were bought as organic Beauregaurd sweet potatoes.
I propped them in jars so half the potatoe is in water and half is above the water. They formed roots, but no green slips are forming?
Is it heat or light which makes them send up green slips?

Neither really. They do have to be warm Above 60 degrees but I have them sprout in dark storage. Mine usually sprout before any roots show. I don't start them in water tho. They will need light for the slips to green up. Beauregard usually sprouts fairly well so you should be good. I just took this photo of a little one that is sprouting in storage.

Thanks-it helps to know what they look like.
I am thinking to move them to a warmer part of house.
And it is easier if they do not need water.

They will need the water to grow so your current plan should work out. I actually grow my slips in a cold frame using grow mix as a medium. I do like them to sprout before I put them down.

I start mine like you do Ms Scott. Mine have also formed roots and no plant growth yet. It will come. I had mine in a window at house temps but just moved them out to the greenhouse for brighter light even though it won't stay as warm at night. I think they tend to sprout when the time is right as they do when they are stored in the dark.
