Establishment
First 12 monthsRecently planted shrubs with visible root development and initial shoot growth
Water deeply and regularly. Mulch around base with 2-3 inches of organic mulch, keeping it away from the stem. Avoid fertilizer in first year.
Young Growth
Years 2-3Shrub develops more defined shape and secondary branching increases density
Continue regular watering. Light pruning to shape is acceptable. Apply balanced, slow-release fertilizer in early spring.
Maturing
Years 4-7Shrub approaches its mature height and form; foliage becomes denser and more vibrant in color
Reduce watering frequency as plant becomes established. Prune lightly in spring to maintain shape. Monitor for pests and diseases.

Minimal pruning needed; trim only to maintain desired shape or remove dead wood. Water during droughts. Fertilize annually in spring if desired.
