This summer we have only had to water occasionally as we are being deluged with rain. When we do water it is when the ground is dry down at least one inch and then we turn the soaker hoses on until it is wet at that depth again. Are your dahlias getting watered at the same rate as your annuals? If so I'm not sure what your problem, maybe overwatering. I know nothing about dahlias. Our annuals out front are basically reseeding perennials now. The poppies come out in January along with the violas and poppies followed by the torenia and then the zinnias. We rooted out the 88 zillion cleomes that came up from one planting. They were floating down the driveway and coming up in the lawn.
