Grayia Hook. & Arn. Propagation
Grayia Hook. & Arn. is a drought-tolerant plant native to the western United States and Mexico. Its unique growth habit and attractive foliage make it a popular choice for xeriscaping and rock gardens. The plant can be propagated through both sexual and asexual methods.
Sexual Propagation
Grayia Hook. & Arn. produces small, inconspicuous flowers in the spring that give way to tiny fruits. The fruits contain small, light brown seeds that can be collected from mature fruits and propagated. The seeds require a cold, moist stratification period to break their dormancy. This can be accomplished by sowing the seeds in a container with moist soil and refrigerating them for at least 3 months. Once the stratification period is over, the container can be moved to a warm, bright location to encourage germination.
Asexual Propagation
Grayia Hook. & Arn. can also be propagated asexually through stem cuttings. In late spring or early summer, select a healthy, non-flowering stem and cut a 4- to 6-inch section. Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone powder. Insert the cutting into a container filled with well-draining soil and mist the cutting with water to keep it moist. Place the container in a warm, bright location out of direct sunlight and keep the soil moist until roots form.
Disease and Pest Management for Grayia Hook. & Arn. Plant
Grayia Hook. & Arn. is a hardy plant that is resistant to most diseases and pests.

To manage leaf spot in Grayia Hook. & Arn., remove infected leaves and apply a fungicide according to the label instructions.
Root Rot
Root rot is caused by waterlogging or poor drainage. It affects the roots, causing them to rot and eventually die. This leads to wilting, stunted growth, and yellowing of leaves. To manage root rot in Grayia Hook. & Arn., improve the drainage in the soil by adding organic matter and avoiding overwatering. Apply a fungicide to the soil as per the label instructions.
Spider Mites
Spider mites are tiny insects that feed on the sap of the plant, leading to yellowing, wilting, and eventually, death. They also spin webbing, which can affect plant growth and reduce its aesthetic value. To manage spider mites in Grayia Hook. & Arn., spray the plant with insecticidal soap or neem oil as per the label instructions. You can also sprinkle diatomaceous earth around the base of the plant to deter spider mites.
Caterpillars
Caterpillars are the larvae of butterflies and moths and can defoliate the plant if not controlled. They chew on the leaves, leaving irregular holes and causing reduced plant vigor. To manage caterpillars in Grayia Hook. & Arn., pick them off by hand, if possible. You can also apply a bacillus thuringiensis (BT) spray to the leaves as per the label instructions.
Aphids
Aphids are small insects that feed on the sap of the plant, causing yellowing, wilting, and stunted growth. They also excrete a sticky substance called honeydew, which can attract ants and other insects. To manage aphids in Grayia Hook. & Arn., spray the plant with a strong jet of water to dislodge them.
