    Was there a stalk on it? If there wasn't, you won't get a plant

    No just the bulb, it enlarged, but did not grow anything

    You need a bit of stalk on the tuber or it won’t grow.

     These Dhalia tubers,only got bigger,with some root growth but no stalk, is it worth keeping them for next year or does it mean they are blind, they were in pots. Lyn did you mean it should have a stalk on it already when planted.

    The tubers (not bulbs) need to have an "eye" to grow a shoot from (usually they're near the previous year's old stalks). Sections of tuber with no eyes won't grow any shoots.

    No stalk = no dahlia. The tubers are just nutrient storage receptacles, they will swell in the ground but there is nowhere (no stalk with embryonic bud lurking) for it to put this energy so I think that’s right, they will be blind and deaf to your ministrations... I don’t think they can spontaneously grow a stalk??

    And I will try and buy decent tubers next year instead of relying on supermarket stock! Grew on a lovely orange one called Colour Spectacle, its been really slow to flower, ways behind all the others. Its finally flowered and its not that one at all - its dusky pink!  :#
