In preparation for winterizing delphiniums, water the plants regularly as winter approaches and continue until the ground freezes so hard it can no longer absorb moisture. Don't water with a sprinkler; get in there with a hose and let it trickle until the roots are thoroughly saturated.

How do you take care of delphiniums in the winter?
If delphiniums sit wet in their dormant winter season, they can die, so make sure you prevent this. They also need plenty of organic matter added to their planting holes when they first go in, then regular feeding throughout their growing season.
Do I cut back delphiniums in the fall?
When winterizing delphiniums, prune the delphiniums during fall flowering using the same stalk removal method as in spring. Cut back the entire plant to the basal leaves once it stops flowering, but leave the foliage in place to die naturally over the winter.
When should you cut back delphiniums?
Early-flowering perennials such as geraniums and delphiniums are cut to near ground level after flowering to encourage fresh foliage and late summer flowering. These are then cut back again in autumn or spring.
Do delphiniums dieback in winter?
Delphiniums are a hardy herbaceous perennial, which means they are tolerant of our winters hardy down to H5, (explanation of frost hardy.) In late autumn and winter they die back completely to bare earth and re grow each spring.
