Earlier in the year I dug up dahlia tubers, gave them a ruddy good clean, put them upside down in newspaper covered pink crates (seen here). I transferred them into the shed (dark spot) but forgot to put them in sand/soil/vermiculite. Do you think they’ll still be okay?
I would have thought so. I always wrap mine in newspaper once they've dried out and store them in cardboard boxes in the shed! Just make sure they get a good water when you plant them out again once the risk of frost has passed! ☺️
Should be ok. Coincidently, I'm trying the opposite this year. Last year I did this and most survived. But they did shrivel a lot. I'm trying something different this year so we can compare notes in the spring 😀 - I've put each one in an individual bag with damp soil and perlite to hopefully just keep up enough moisture.
