A few months back I asked for a bit of help from the growers of the Warm Climate Dahlia Growers Group on Facebook. I asked them to share their growing zone, general geographic location and planting dates. I’ve compiled them into a spreadsheet that gives an overview of planting dates for Zones 6b-10b.

You can view the chart below. As always, consider your unique climate and also your last frost dates. If you’d like to contribute to the data, please send me an email via our Contact page.
