Pruning

Proper pruning plays a crucial role in maintaining the health, shape, and flowering performance of Caryopteris incana ‘Jason’ Sunshine Blue. Pruning tasks should be performed at specific times to achieve the desired results:

Spring Pruning: In late winter to early spring, before the onset of new growth, prune back the previous year’s growth to a few inches above the ground. This stimulates vigorous regrowth and ensures a compact and bushy form for the upcoming season.
Deadheading: After the initial flowering period, promptly deadhead spent blooms to encourage the production of new flower buds and extend the flowering season. This practice also prevents the plant from self-seeding, maintaining its well-manicured appearance.

Selective Pruning: Throughout the growing season, selectively prune any straggly or overcrowded branches to maintain an attractive and balanced silhouette. Focus on removing dead, damaged, or crossing branches to promote airflow and reduce the risk of disease.

Propagation

Propagating Caryopteris incana ‘Jason’ Sunshine Blue (Bluebeard) can be achieved through several methods, including:

Softwood Cuttings: In late spring to early summer, take 4-6 inch semi-soft cuttings from the current season’s growth. Remove the lower leaves, dip the cut ends in a rooting hormone, and plant them in a well-draining propagation medium. Provide bottom heat and consistent moisture to encourage root development.
Hardwood Cuttings: During the dormant season in late winter to early spring, harvest 6-8 inch hardwood cuttings from the previous year’s growth. Insert the cuttings into a prepared propagation medium and place them in a sheltered location with indirect light. Keep the medium slightly moist and monitor for the emergence of new shoots as a sign of successful rooting.
Division: Divide mature Bluebeard plants in early spring before new growth emerges. Use a sharp, sterile tool to separate the root clumps into sections, ensuring that each division has several vigorous shoots and a healthy root system. Replant the divisions in suitable locations and provide consistent moisture and protection until they become established.
