Tips for Propagating Delphiniums from Seeds

Selecting the right type of seeds

When propagating delphiniums from seeds, it is important to select high-quality seeds from a reputable source. Look for seeds that are labeled as specifically for delphiniums, as this will ensure that you are starting with the best possible genetic material. Additionally, choose seeds that are fresh and have not been stored for too long, as older seeds may have a lower germination rate.

Preparing the soil for sowing

Before sowing delphinium seeds, it is important to prepare the soil properly. Delphiniums prefer well-draining soil that is rich in organic matter. Start by loosening the soil to a depth of at least 6 inches and removing any weeds or debris. Mix in some compost or well-rotted manure to improve soil fertility and structure.

Sowing the seeds and caring for seedlings

When sowing delphinium seeds, it is best to do so in early spring or late summer, as these are the times when delphiniums are most likely to germinate successfully. Sow the seeds thinly and cover them lightly with soil. Keep the soil consistently moist but not waterlogged, and place the seed tray in a warm, sunny location.

As the seedlings begin to emerge, thin them out to ensure that each plant has enough space to grow. Once the seedlings have developed a few sets of true leaves, they can be transplanted into individual pots or directly into the garden. Provide regular water and fertilize as needed to help the seedlings establish and grow into healthy, vibrant plants.

Tips for Propagating Delphiniums from Cuttings

Choosing the right time for taking cuttings

When propagating delphiniums from cuttings, it is important to choose the right time to ensure successful rooting. The best time to take cuttings is in the early summer when the plant is actively growing. Avoid taking cuttings during extreme heat or cold, as this can stress the plant and reduce the chances of successful propagation.

Preparing the cutting and rooting hormone

Before taking cuttings from your delphinium plant, make sure to use clean, sharp scissors or pruners to make a clean cut. Cut a 4-6 inch piece of stem from a healthy, non-flowering part of the plant. Remove any leaves from the lower half of the cutting to prevent rotting. Dip the cut end of the stem in a rooting hormone to promote root development.

Caring for the cutting until it roots

After preparing the cutting, place it in a small pot filled with a well-draining potting mix. Keep the cutting in a warm, bright location away from direct sunlight. Make sure to keep the soil moist but not waterlogged, as this can cause the cutting to rot. With proper care and attention, your delphinium cutting should root and begin to grow within a few weeks.

Tips for Propagating Delphiniums through Division

When it comes to propagating delphiniums through division, there are a few key tips to keep in mind to ensure success.

Choosing the right time for division

It is best to divide delphiniums in the early spring or early fall when the plant is not actively blooming. This will give the divided sections the best chance to establish themselves before the plant enters its flowering stage.

Preparing the plant for division

Before dividing your delphinium plant, make sure to water it thoroughly the day before. This will help loosen the soil and make it easier to separate the roots without causing damage. Use a sharp, clean knife or shovel to carefully divide the plant into sections, making sure each section has both roots and shoots.

Replanting the divided sections

Once you have divided your delphinium plant, it is important to replant the sections in a suitable location. Choose a spot with well-draining soil and ample sunlight. Dig a hole slightly larger than the root ball of the divided section and gently place it in the hole. Water the plant well after planting to help it establish roots in its new location.

By following these tips for propagating delphiniums through division, you can successfully propagate your plants and enjoy beautiful blooms year after year.

Other Creative Ways to Propagate Delphiniums


Layering is a simple and effective method to propagate delphiniums. To propagate through layering, select a healthy and strong stem from the parent plant. Bury a section of the stem in soil, leaving the tip exposed above ground. The buried section will eventually develop roots and can be separated from the parent plant once established.

Air Layering

Air layering is another technique to propagate delphiniums. To air layer a delphinium plant, make a small incision in a healthy stem and wrap it with moist sphagnum moss. Secure the moss with plastic wrap and wait for roots to develop. Once roots have formed, the stem can be cut and potted as a new plant.


Grafting is a more advanced method of propagation that involves joining a piece of a delphinium plant (scion) with a compatible rootstock. This technique can be used to create new varieties or to propagate plants that are difficult to root. Grafting should be done carefully to ensure a successful union between the scion and rootstock.


In conclusion, propagating delphiniums can be a rewarding and enjoyable process when done correctly. By following the tips and tricks outlined in this article, gardeners can successfully propagate delphiniums in a variety of ways, from seeds to division. Whether you are a beginner or experienced gardener, there is a method that will work for you. With patience, care, and a little bit of experimentation, you can enjoy the beauty of delphiniums in your garden for years to come.
