Can potted dahlias go outside now?

Hi all

I brought some dahlia tubers recently and potted them up in some compost to prevent them drying out until I can plant outside once the risk of frost has passed. I brought them out of the garage this week in the nice weather and gave them a bit of water as the soil was really dry, not sure if that is right. I have left them outside all day/night the last few nights as there is no forecast of frost due, does anyone know if I can just leave them outside permanently now providing there’s no chance of frost? I live in the West Midlands if that’s relevant. 

Thanks for your help!

    The forecast is for a cold spell. I would pop them back in the garage at night until it warms up.

    I will be planting mine out in June,  the bigger they get in pots the better for the plant, gives them chance to fight of the slugs a bit.

    Hiya and welcome to the Forum.
    Like @Lyn, I'm in Soft , mild Devon and I'd not put Dahlias out for several weeks yet. 
    Next week we're forecast a MAX of 5C and a MIN of 2C. Way too cold for th.em

    The last few nights have been +8 degrees (probably more in my garden) so probably OK. The next few days have overnight temperatures around zero forecast so you would definitely not want to leave them out. (Even if we do have a warm spell, as Lyn says be mindful of the damage a single slug could do to those young shoots, it's probably not worth it).

    You're asking for trouble if you do.

    I haven’t started my dahlias yet - they’re still wrapped up in the garage. Usually I start them off mid to late March, but this cold spell of weather is difficult.  I only have plastic covered cloches to grow them in.  I have about 75 tubers and they are mostly for containers rather than the garden.  I will put them out at the weekend in cloches, I think, with fleece at the ready to tuck inside the greenhouses.  I’ve the same dilemma with seed growing as well
