Grief, that's annoying. Have you lifted one of the 'dormant' ones for a look (I would but I am a meddler and poker). Can you see the crown end? I have had bagged tubers which have been in terrible shape, with badly damaged necks and no sign of eye growth so I usually buy rooted cuttings...although you have to get your orders in well early., so often miss out. Probably just as well.

So yep, I would be digging one out and having a good look. Maybe replant with the neck end actually exposed to light...that can help get reluctant tubers going, especially with a little bit of extra heat (I used to keep mine on top of the fishtank light).

My dahlias have been awoke for a while and are a couple feet tall (really must nip them out quicksmart). Most were grown from seed so I don't really have any special named types, but they do eventually make enormous tubers (can see why they had been grown as a food source). Still early days for you, maybe? I still have a few things I know (hope) are alive despite no sign of any sprouting...including a massive salvia (although in this case,I had secretly been hoping it had carked cos it is gigantic and now I have to dig it out of the ridiculously overstuffed raised bed). Anyway, best of luck with yours...maybe take some cuttings of the ones which have sprouted, if you want to fill more space.

Thanks Rosa, I'm also a poker arounder and carefully lifted all the laggers and washed off the crowns / necks to give a check. Appears one "might" be deciding to awaken. I did replant as you suggested to better expose to sunlight and warmth. I had watched video of a Dutch dahlia harvesting machine at work and those things are calibrated to shake the living daylights and break as many tuber necks as possible it seems! This first photo is all that was left after having removed all the very many broken necks, this particular tuber never developed any roots, the dark spot that appears like a potential eye was though decayed and upon further inspection the entire tuber was spoiled inside. The thriving plant behind it had arrived with the same order.

This one appears pretty hopeless, plenty of rooting, though things are all recessed and weird where last years stalk had been, will keep exposed to air and hope for the best!

This one "seems to be" showing a bit of life on the opposite side, mmmm, maybe!

I'd be curious to try a dahlia dish or two, they smell kinda strange and never been tempted to take a nibble, though not apposed to actually preparing some.

Has been a slow miserable spring, very few days of any real warmth and so often overcast and rainy, moisture is good, but farmers need opportunity to finish up the seeding. Cool weather perennials are happy, heat lovers biding their time.

Oh, next year will place newly purchased tubers in a plastic bag to keep in a warm bright location Had divided a large tuber and left for only about a week or ten days as such and so very quickly it had thrown all sorts of sprouts!

My eldest tried some - he said it was a bit like a gritty potato but weirdly sweet. And tricky to cook (I think he roasted it in the skin). If you consistently leave them in the ground to overwinter (quite doable here, especially with my lean, free-draining soil), they do make a gigantic tuberous mass.

Ages ago, in my veg growing days, I did attempt to grow and eat various 'edibles' including oca, , mashua and a daisy -ish thing ( yacon? name eludes me). All either fiddly to prepare (mashua), tiny and took ages to grow (oca) or kinda horrible (yacon). The tropaeolum did have interesting flowers though. Also spent several seasons attempting to grow apios (hopniss) resulting in about 2 minuscule tubers the size of a peanut.

I have one root which is now sitting for 2 months and refuses to awake :( I never had this situation before. I have lifted the root, it has many little roots at the ends, but not visible at its stem. So weird! I have planted it to my big planter now and decided to leave it alone 😂

I had meant to get back to this thread. Rosa, come autumn, I'll give some 'yummy" roasted dahlia tubers a try, lol. I'm willing to attempt almost anything, though dahlia tubers have a funky odor that I can't imagine to much enjoy the taste of, though who knows! I also grow apios Americana, nice lush wisteria like foliage, I nibbled a bit upon a tuber, it was very dry and flavorless that I imagine only a good deal of cream, butter, salt and pepper could bring any life to it!

The above two dahlia tubers remain without advancing any signs of life, that's a total of five of twelve tubers that are duds this year, I've begun contacting the suppliers. Regruta, sounds like your dahlia is playing the same games as mine!

Well, those two tubers have refused to awaken, so I guess they never will!

Suzy, I had meant to reply back sooner, sounds like such a discouraging spring there as well! I can't really say I've lost all that many plants, but the weather has been terrible with BC and Alberta being locked into a cool, cloudy and WINDY pattern for almost four entire months! We often struggle to get anywhere near normal temperatures and the next few days it's just gonna be chilly! As for the veggie gardens, currently it's not the slugs, but once again the cold, gardens are many weeks behind, anything requiring warm ground to germinate has rotted, beans, cucumbers, corn. I grew a new variety of tomato called 'Roadster', well it sure in the heck must be sensitive or something, while all other varieties have developed normally, 'Roadster' is a sickly yellow. I've had to install a makeshift greenhouse over the tomatoes, otherwise they're be relentlessly weather assaulted! I don't know, with the weather patterns as such, I'm not feeling overly optimistic, last year was a total sopping washout! :(
