Has your dahlia flowered yet?

Hi, just wondered whether anyone else is still waiting for their dahlias to flower?  This one was new last year and managed to survive the winter in the ground but has been really slow to get going due to the lack of warmth this summer.  I go out every day to give it some moral support and am keeping my fingers crossed for this weekend 🌸

    Giving some tomato feed might give them a kick in the pants. My smaller varieties have been fine. The larger ones have had sluggish flowering. I also haven't been watering enough.

    Mine varied depending on variety... Blue Bayou was the slowest, Waltzing Matilda the earliest. Without giving them an early start under grow lights I would probably still be waiting for Blue Bayou to flower. Matilda has been incredibly good, really strong growing and floriferous.
  • Yes a high potash feed will help flowers.  My singles have been flowering since July,  the larger ones were a bit later but are in full flow now.

  • Spring was late and chilly this year … consequently some dahlias left planted in the garden over winter were slow to get going. This means that those that would normally be later flowering are now very late.

    Even in the south  I would always lift the later flowering dahlias for the winter because they need a longer growing season … lifting them means that they can be started off under cover earlier than they would get going outside.

  • My dinner plates are late, last. week was my eldest daughters birthday, seeing her today, picking a bunch it will be smaller than normal
     I don't mind though because it's some nice late season colour
