Leave some in,you can put bark chippings or straw over the crowns,I use my own compost,then I cover that with a wicker hanging basket just to keep it in place. We're also on clay, although 1O years improved. Sometimes wet rots them,and slugs scoff the tubers. Never heard of mulching before frost. Monty always says after frost had blackened the tops. Do you have anywhere you could store some?

When you say when the frost has blackened the tops, do you mean when the foliage turns black? Mine was going black which is why I cut them back, maybe I was too early?
I don't think you were too early. They should be fine so long as your soil is not very wet and it sounds like a good situation. Wet, heavy clay is a real problem but you don't have that!

I did have an olive tree on the same sloping bank which did very well so I’m hoping the dahlias will do as well!!🤞🤞
Yes,if they're going black no problems . I've taken a few in because I needed the pots. Hubby grew them from a free packet of seeds in March,they have really good tubers. They are going in a box of straw in the garage,that's trial run.
Sorry it’s me again! I managed to get to get some farmyard manure, I have already cut them down but haven't had a chance to mulch them today as it hasn’t stopped raining. Is this okay, leaving them a few days between cutting and mulching? The saving grace is we haven't had any frost. Thanks again.
Yes, it's fine. The mulch is to protect against cold and we haven't had any yet - at least, not as far as I know. You can mulch any time before the frost but doing it while the soil is still warm is a good idea.
