Overwintering Dahlia cuttings

I took four Dahlia Clarion cuttings in early August. All four have taken and they are about 3 inches length in separate pots with clusters of healthy leaves.

I'm just wondering what to do with them over winter. They are too young to have any tubers, should I bring them inside and keep them watered over winter on a window cill or should I let them wither inside without any attention or perhaps I should just leave them outside in the cold to wither away.

Many thanks

 

My gut feeling is you need to keep them in growth this winter, but best just ticking over.
Not sure how easy that is, but a window sill might be the best option,without grow lights.

 

keep on the window sill and keep them ticking over , dont over water and remember it can get cold on a windowsill if frost is expected , they should be fine .

Definitely keep them warm, but you might find that they get a bit leggy due to the lack of light during winter. Its more normal to take Dahlia cuttings in spring when the conditions are a bit more conducive to good growth. If you manage to keep yours growing then you could take the tips out in spring and use these for even more cuttings.
