Can you explain exactly what happened. Are there leaves and no flowers?What is your location?
Perhaps it is the soil, or they have been too much in blossom, and are tired. I would let the flower blossom for a bit, and then cut them back, just a little, and then they will grow and take on blossoming again. Just try this, and if it works, let us know, for we will rejoice with you, ok? In the late fall, be sure to cover the plant, or bring it in, thru the winter, just to rest, in a cold area. If you are going to cover it, Use leaves, then put dirt over the leaves, and then put a pail, or a large sq. container over this plant, and I put bricks on it, to keep it down, with the high winds. Best wishes, J.
I know this may sound crazy, but did you let the plant over-bloom? I have read that if you let a delphinium over-bloom, the plant will literally die of exhaustion. First year, only 1 spike, second year 3-5, third year five. And don't let the flowers stay on the plant until they go to seed.
Delphinium plants are short lived, meaning they are not perennials that will live in the garden for years, they could live to 3 years but many times they do not. There are many plants that are short lived, talk to your local nursery.
happy gardener

I think some plants are biennial....I had a Joseph's coat that only bloomed two years and then did not come up. I am wondering if delphiniums could be biennials also . I have grown them and they are beautiful, but don't remembrer then lasting more than two years.
My plant expert tells me they're definately biannual.
We had delphiniums at home for years and years and always showy. I struggled with them at a different home and assume it may be the dirt.
Maybe, we have a rich soil here in southern NY.
Same problem they died after 2 years soil grows most everything else well.
