4-6 weeksRecently transplanted shrub with initial root development and leaf acclimation to new location
Water frequently to keep soil moist. Avoid fertilizing for first 2-3 weeks. Provide afternoon shade if planted in hot climates. Mulch around base to retain moisture
Vegetative Growth
Spring through early fallActive leaf and stem development with new shoots emerging from nodes. Plant fills out and establishes fuller canopy
Water regularly during dry periods. Apply balanced slow-release fertilizer in spring and early summer. Prune lightly to encourage bushier growth. Watch for pest issues
Established Mature
Year 2 onwardFully developed shrub with dense foliage and well-established root system. May produce small, inconspicuous greenish flowers in spring
Reduce watering frequency as drought tolerance increases. Fertilize once yearly in spring. Prune to maintain desired shape and size. Thin crowded branches for air circulation
Dormancy
November-MarchWinter period with slowed growth; foliage remains on evergreen plant. Some varieties may show color changes
