    Default Dahlias damaged by frost

    Hi all, I have 6 dahlias (one of each Bishop). 4 are in the ground now and two still potted in a cold frame. Over the weekend I was away and all 6 of them have been caught by the frost and their foliage is dead and shrivelled.

    What should I do now? will they grow back?

    thanks in advance

    Alex

    They might grow back. I leave my dahlias in the ground all year, and about half of them come back after the winter

    they are new tubers so not sure if that makes them any more vigorous or not. As it happens some of them have a little bit of green growth at the bottom so I have bought some of those rediculously expensive plastic bell cloches to put on top.

    Maybe yours have been caught worse by the frost hense no signs of life?

    Hi

    Stick it out for a bit yet. I would always lift and start mine in a shallow tray (cat litter type) so the top of the tuber was showing. I would then take cutting when the shoots were about 3'' high before placing back into the ground to grow on and flower. I've had then grow after a winter of -8 to -10, so although they have had a shock I would hope they would recover.

    Newton- try lifting yours if you know where they are. If they are mush then you know they are lost. However a good firm tuber should sprout eventually!

    Hope so of this helps

    Dave

    Couldn't agree with this one more. I found a great selection of Dahlia Tubers at Lynch Creek Farm and decided to purchase 4 varieties of it. I planted them in my garden, and just like yours, my dahlias were caught up by the frost. After the winter, they grew back as if nothing happened.

    You expect to get them caught by the frost at the back end of the year as this signals it is time to lift them and store them for the winter.
    It's different if they get frosted early in the year, especially if grown from cuttings as they haven't formed tubers at that time!.
    Hope they recover!
