Plant Propagation Methods:

Ceanothus ‘El Dorado’ can be propagated using both sexual and asexual reproduction methods. Sexual Reproduction:

To propagate Ceanothus El Dorado through sexual reproduction, take cuttings from the plant during the summer months when it is actively growing.

Cuttings should be about four to six inches long and have at least two to three sets of leaves on them. Remove the leaves from the bottom of the cutting and dip the stem in rooting hormone before placing it into a well-draining potting mix.

Water the cutting and place a plastic bag over it to retain moisture. The cutting should root in about six to eight weeks.

After the cutting has rooted, transplant it into a larger pot or directly into the ground. It might take a couple of years for the cutting to establish itself and start blooming.

Asexual Reproduction:

Asexual reproduction of Ceanothus ‘El Dorado’ is possible through layering. Layering involves creating a new plantlet from the existing plant without severing it from the parent plant.

To do this, select a low-growing branch of the Ceanothus ‘El Dorado’ and bend it to the ground, making sure it remains in direct contact with the soil. Then make shallow cuts along the length of the branch where it touches the soil.

Cover the branch with soil, water it, and keep it moist. Typically, roots will form at the cuts, and within six to eight weeks, new plants will start to appear.

Once the roots are strong enough, sever the new plantlet from the parent plant and transplant it to a new location. The new plant will quickly establish itself as it has already developed a root system.
