Propagation by Seeds
The seeds of Callistemon 'Packer's Selection' can be collected from mature fruits and sown during the spring season.

Propagation by Layering
Callistemon 'Packer's Selection' can also be propagated by layering. This method involves partially burying the stem of the parent plant while keeping the tip above the soil surface. In response, the buried portion of the stem will send out roots, and once sufficient roots are established, the stem can be cut and planted in its permanent location.
Disease and Pest Management for Callistemon 'Packer's Selection'
While Callistemon 'Packer's Selection' is generally known for its resilience, it is still susceptible to several diseases and pests that may damage or kill the plant if left untreated. Knowing how to identify common diseases and pests and implementing prompt control measures is crucial to keeping your plant healthy.
Common Diseases
Leaf spot disease: This is a fungal disease that manifests as small brown or black spots on leaves. It is usually caused by overwatering or poor air circulation and can spread quickly in wet conditions. To manage this disease, improve air circulation around the plant, avoid overhead watering, and apply a fungicide.
Root rot: Root rot is caused by waterlogged soil conditions and can quickly kill the plant. Symptoms include yellowing leaves, stunted growth, and root discoloration. To manage root rot, remove affected roots, improve drainage by amending the soil with sand or perlite, and avoid overwatering.
Anthracnose: This fungal disease affects the stems, leaves, and flowers of Callistemon 'Packer's Selection' and can cause defoliation and stunted growth. To manage anthracnose, prune and dispose of affected stems and branches, improve airflow around the plant, and apply a fungicide.
Common Pests
Spider mites: These tiny pests are difficult to detect but can cause significant damage to the plant by sucking the sap from the leaves, causing them to turn yellow or brown and stunt growth. To manage spider mites, wash your plant regularly, prune affected areas, apply a horticultural oil or insecticidal soap, and increase the humidity around your plant.
Scale insects: Scale insects attach themselves to the leaves and stems of plants and suck the sap, causing the plant to wilt and develop yellow leaves. To manage scale insects, manually remove them with a soft brush or cloth, apply a horticultural oil, or release beneficial insects that feed on scale.
Aphids: Aphids are small, soft-bodied insects that suck the sap from the leaves and cause them to curl and yellow. They also produce a sticky substance called honeydew that attracts ants. To manage aphids, wash your plant with water, prune affected areas, apply insecticidal soap or a horticultural oil, and release beneficial insects that feed on aphids.
Regularly monitoring your Callistemon 'Packer's Selection' for diseases and pests, as well as implementing prompt control measures when necessary, will keep your plant healthy and thriving.
