I'm sure PH did better with dahlias than me. Now I see why they require such careful care. They grow much, much more slowly than the grass and weeds. Mine also all got brown rot of the flowers, probably from poor ventilation. I would guess they also require periodic fungicide, at least in my climate. This explains why I don't know anyone locally who grows them.

Cut flowers have been too much work for too little money for me. I am going back to tomatoes next year.
