Propagation of Ditaxis Serrata var. Californica
Ditaxis serrata var. californica, commonly known as the white crucifixion thorn, is a deciduous shrub that is native to California and Arizona. It is an ornamental plant and is often grown in gardens and landscapes. Propagation of this plant can be done through several methods.
Seed Propagation
The most common method of propagating Ditaxis serrata var. californica is through seeds. Seeds should be sown in the spring in a well-draining soil mix. Seeds should be lightly covered with soil and kept moist until they germinate. It is important to note that germination can take up to two years, so patience is key. Once seedlings have reached a height of 2-3 inches, they can be transplanted to their permanent location.
Cuttings Propagation
Another way to propagate Ditaxis serrata var. californica is through cuttings. Cuttings should be taken in the summer from semi-hardwood stems that are about 6 inches long. Cuttings should be stripped of their lower leaves and dipped in rooting hormone before being placed in a well-draining soil mix. The cuttings should be kept moist and placed in a shaded area until they root. Once roots have formed, the new plant can be transplanted to its permanent location.
Division Propagation
Ditaxis serrata var. californica can also be divided in the early spring. The root ball should be dug up, and the plant should be divided into sections. Each section should have a healthy root system and several stems. The new plants should be planted in well-draining soil and kept moist until they become established.
