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.

Encouraging a Second Flowering

Keep the cutback plant well-watered and wait for new growth. With the right care, you can expect a second display of flowers later in the season.

Preparing for Winter

The best time to take cuttings is in spring when new shoots are about 3 inches tall or after the first summer flowering when the plant starts to regrow4.

Taking Cuttings

Select young stems and cut them close to the base, including some of the hard brown callus material found there, which aids in root formation4.


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.


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