I have a Dhalia (Langstaff) in a pot. Now all the leaves are covered in a
dusty thing....fungus? Is it normal for Dhalias to have this problem? Anyway
to prevent it?

Powdery mildew. Not much you can do now about it. A fungicide next year
when the leaves emerge. Try Organicide next year.

Thanks Tom. Should i cut it now or wait until the first frost? (It looks
awful...)

Thanks again

Dhalia and Greggia?

Do you mean Dahlia?

Not a good plant to grow in pots because of the tuberous roots. If the
leaves have mildew its because the plants have been kept too wet in a humid
atmosphere. Give them moving air.

Greggia?
The plant is in the balcony, a lot of wind there...but we are having a very
humid summer. I have to keep it well watered or the leaves look wilted. At
the beginning of the summer looks beatiful...but not anymore

You can do either but don't compost the infected leaves.
