When planting, dig a generous hole and mix some well-rotted compost or manure into the soil to enrich it before backfilling. Also incorporate mycorrhizal fungi to boost establishment. After planting, apply 5-7cm (2-3in) of organic mulch around the base to retain moisture and suppress weeds.

Prune after flowering, as needed, to maintain shape and control size, removing any old, crossing, or misdirected stems. Dormant pruning before spring helps rejuvenate the plant, but heavy tip pruning is generally not required unless shaping is desired. Thinning the interior improves airflow and overall health.
