This is my first try at dahlias. I ordered a few recommended for the heat/south and planted them in large pots, directly against my 6 ft privacy fence. They are about 3 ft tall and one variety has buds. The last few nights, something is decimating them, starting from the bottom going up. The leaves don't have holes. They are almost completely gone. Even the stem where it is connected to the main stalk is broken in places. I live in town and the neighbor's dog stays out at night opposite my plants. I put out little bowls of beer and crumpled newspaper. Didn't catch any slugs, but not sure about the earwig thing. I checked at 6:30 this morning and nothing was in the newspaper, but maybe I didn't "trap" correctly. I don't think it is a bug because of the broken stems. There were three different varieties, two of which were obviously the tastiest. The last plant is missing a few leaves at the bottom this morning. Any ideas?
