Establishment
6-12 monthsNewly planted shrub with developing root system; slow growth during first year
Water regularly to keep soil moist but not soggy. Mulch lightly around base. Avoid fertilizing first year. Prune only to remove dead or damaged growth.
Vegetative Growth
Ongoing, years 1-5Dense, compact foliage develops with characteristic fine, small leaves; gradual widening and height gain
Water consistently during dry periods. Apply balanced fertilizer in spring if desired. Begin light shaping/hedging as shrub reaches desired form.
Mature Form
Years 5-15+Reaches desired size and full density; thick, dark green foliage forms solid mass
Maintain shape with light pruning/shearing in late spring or early summer. Reduce watering needs as root system matures. Continue light fertilizing annually if desired.
Renewal Pruning
As needed, every 10-15+ yearsOlder shrubs may benefit from more intensive rejuvenation if growth becomes sparse or leggy
Can cut back to 12-18 inches above ground in late winter/early spring. New growth will emerge to fill in bare areas. Recovery takes 1-2 seasons.
