When to cut back delphinium? Once the initial flowering period ends, usually in early summer, cut the entire plant back to ground level. This may seem drastic, but it stimulates the plant to produce new shoots that can flower in the autumn.

Preparing for Winter

Cutting back delphiniums for winter; as fall approaches and the foliage begins to die back, give your delphiniums a final haircut before winter arrives.

Taking Cuttings

Rooting

Dip the cut ends in raw honey or rooting hormone, then plant them in a mix of potting soil and sand. Cover with a plastic bag and place in a bright area, but not in direct sunlight.

Transplanting

Once roots have developed, transplant the cuttings to your garden, ensuring they have enough space to grow.
