I note that Chris says keep them uncovered and dry. yet Monty says keep them covered and moist. I will, as ever, ignore Monty's advice.

Don't - dahlias can dry up and die if they get too dry.

I pot up dahlias and keep dry. I dig up tubers and leave them uncovered in the greenhouse. I leave dahlias in the ground. Albeit I'm in mild SW I have only lost dahlias through rot. Did Monty say keep them moist? How can you do that with tubers? If tubers are now fat n full I think keeping them dry and frost free is best. Keep in greenhouse, wrap in fleece and in cardboard boxes.

To clarify-he stored them in a box with vermiculite and he damped the vermiculite-he did not say keep them moist -just not to completely dry out-I find they seldom completely dry out and I cover mine with newspaper

His were kept in frost-free greenhouse where the temperarure did not drop below 5c as I recall so pehaps a tad warmer than usual and he also said to inspect them occasionally-good advice

If you think about if kept in the ground they are never going to dry out and always be moist

It is as usual what works for you-ignore what you l like-but why "as ever" Hostafan 1?

By contrast, I've never had any problem with rot in an airy garage, but I have lost them through drying out. As Geoff says, they never dry out in the ground.
