Spring and summer are the greatest times to take cuttings because the plant is actively growing.
To avoid unnecessary harm and disease transmission to the parent plant, use an extremely sharp, clean knife or razor blade. Cut a 3 to 4 inch (7.5 cm) long cutting straight across the tip of a leaf. To keep latex sap from oozing out of the cut end of the parent, spray it with cold water.
The following stage in reproducing crown of thorns by cuttings is critical. Allow the cut end of the cuttings to callus on newspaper in a cool, dry location. This encourages the growth of cells that can become roots, as well as preventing rot when the cutting is placed in soil. It normally takes a few days, and the finished product will be puckered and grayish white.
