Help! We live in Canada and bought a 10x13 ft greenhouse this June. We bought 4 beautiful dahlia pots, 4 tubers in each. They have been amazing but our 1 bright red one went limp. We have tried not watering, fearing too much water, cinnamon for fungus, it’s had a good fertilizer, but all 4 plants are now completely limp. We’ve pulled 2 To try to pot them separately. Now we are worried we have some dahlia disease. And, tonight one of my Shasta daisy blooms did the same thing! Not sure if it something to do with the greenhouse or us. Any help would be appreciated!

also, is 4 dalias too much for a 12” diameter pot? That’s how they came.

    Welcome!  What part of Canada are you in?  It's probably too hot in the greenhouse for plants right now.. unless you are up in Nunavut.. do you have a fan running and do you open the door and vents during the day?  Neither dahlia or daisies need to be inside now.  
    Post the images of the plants and a few close-ups of the leaves, stems, etc.  Could possibly be a pest, as they are more common in greenhouses.
