    Morning Woo :)
    it all depends on the size of tuber but I plant small tubers, those usually available in stores, etc., in 1 litre pots. Spread roots out and just cover tops of tubers. They grow fast in early spring so be ready to pot on when roots start emerging from the bottom of the pots.
    Water very lightly at first and repeat and increase when shoots are seen.

        Dahlias grow huge here Woo :).....some over 7’ tall ....most remain in the soil over the winter and already shooting.
        In pots it is the little slugs who cause most damage I think. I regularly look under pots (all plants and seedlings in pots) for the blighters and often they are lurking there so this is one thing you can do. Esp important that metaldehyde pellets will be banned soon. Whilst still available a couple of pellets per pot is enough to protect dahlias......folks make the mistake of over using pellets; too many and they don’t work!
        Incidentally, I once hated dahlias...thought they were gaudy, tasteless and, apart from sheer colour, had nothing to recommend them. However, I have come to appreciate them a whole lot more and prob now grow 30 or more of them. Check out the single flowered ones too like the Honka varieties
        Fingers crossed Woo you will have a summer of dahlias this year :)

          There are different types of dahlia.....cactus, Pom Pom, anemone, decorative and more Woo according to the type of flower heads. Also miniature, giant, tall, short etc.
          I think you will find decorative are the most common group.....a dahlia expert hopefully will comment :)
          Anyway, all grown basically the same way Woo.
