Dahlias are the last great blooms of the summer, as beautiful as peonies and iris. I appreciate having these spectacular flowers as summer wanes.
Here is New Hampshire dahlias are not hardy. I start them in early may in trays of loose potting soil, just early enough to have a little sprout of foliage. I have had trouble starting them directly in our cold, wet spring soil.
To hold them over they have to be dug up in the autumn and stored over the winter. I use vermiculite which needs to be a little damp. I must admit I often lose my dahlias over the winter, they sometimes shrivel, sometimes rot. But they are beautiful so I keep buying new roots each spring.
