I received and potted up a load of new tubers on 3rd March and put them in the poly. It’s been fairly cool and wet since then here, so I’m amazed they are so far on, here they are enjoying a bit of weak sun outside:
These were from Peter Nyssen.
My cheapo tubers from Lidl last year enjoyed a warmer spring, but took far longer to sprout. Still put on a good display though and I left them in the ground. They emerged early, got frost-bitten but are now recovering... just in time for the snails to appear.
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
I stored some of mine (forgot some in pots (dwarf varoeti)es)and they are shooting) and potted them up last week. They are starting to shoot, they are all dinner plate types I've got some cactus and waterlkly type tubers on the way and some seed. It'll be interesting to see how the seeds turn out as I know they arent true to the parent plant (so I've been told) I should get some nice dahlias all the same! I'll start planting them out mid may. I'm in Derbyshire. I've managed to stop slugs getting to the new shoots in the past by putting mini clotches over the emerging shoots. Beer traps are also good.
Here in the Vendée - a mite warmer than Yorkshire - the ones left i the ground are only just starting to shoot and I have to get really close to see them. The new plants I bought this spring in those bags they sell in SMs and GCs had teeny shoots already and were potted up in the polytunnel. Those teeny shoots are now only 6 or 7cms high and new shoots are just showing.
I wouldn't worry about yours yet but I would check regularly for the need to protect juicy new shoots against slugs and snails and also surprise frosts.
Vendée - 20kms from Atlantic coast.

i potted them up and had them in the house from when Gardeners world mag said it was time to start them. Roughly 1st week in March.
Being new to Dahlia’s last year I may have let to many shoots develop on the Bishop of Dover as it is huge.
