First time Dahlia grower!

Ive still got my dahlia plants (grown from tubers) on a windowsill. Should I start to harden them off yet? I'm away on holiday next week so wondering how to keep them alive while I'm away. Many thanks!
But well-watered in a shady and sheltered part of the garden should see them through.
Enjoy your hols!
Wisdom is not putting it in a fruit salad.
My dahlia's are in my cold frame and are thriving. I am in neighbouring Surrey so I think you should be fine.
If you are concerned about the cold just makes sure you close the lid on your cold frame each nigh if possible.
If you leave them in the pots the best advice I can give following that given by other posters is please don't leave them on trays of water or where rain could collect in trays /saucers. Tubers rot very easily when in wet compost. If they are a little droopy when you get back from holiday they'll soon perk up after a soaking.
