Dahlia cuttings

In the middle of summer, having read an article by Carol Klein, I took cuttings of a large cactus dahlia - just to see if I could! I now have six lovely plants growing in pots in a cold greenhouse. What do I do next? Do I pot them on? They have developed a good root system. Do I leave them to let the foliage die back and then do nothing until next summer? How do I keep them alive over the winter? When will they develop tubers? (I haven't had the heart to empty one out and scrabble amongst the roots to see if there is a tuber there.) Will they bloom next year? The parent is called Painted Lady and is white blotched with red. Big and blowsy and lovely. I'm so amazed at how easy it is to propagate in this way - I feel like its midwife! Thank you Carol. Advice would be welcome, please.

unless you can keep them frost free, they'll die back in winter. They probably have some form of tuber already, it doesn't take long. Let them dry out after they die back, keep them frost free, shed, garage etc and wait until spring, Start to very lightly water in spring and they'll be well away. Painted lady is a good " dooer" , bulks up quickly.
My dahlias flowered two years running and this year they grew but no flower
