Establishment (Year 1)
12 monthsYoung transplant with compact pyramidal form, dark green foliage; active root development occurring below ground
Water consistently to keep soil moist but not soggy. Avoid fertilizer first year to prevent soft growth. Mulch around base. Stake if necessary to maintain upright form.
Vegetative Growth (Years 2-4)
3 yearsSteady upright growth with densening foliage; maintains narrow pyramidal shape naturally without excessive pruning
Water during dry spells. Light pruning only to maintain shape if desired. Apply balanced slow-release fertilizer in early spring. Monitor for pest issues.
Maturing Growth (Years 5-10)
5-6 yearsFilling in nicely with dense, deep green foliage; reaches functional size for screening; slow growth rate becomes more apparent
Reduce watering frequency; plant is drought-tolerant when established. Prune lightly in early spring if shaping hedges. Fertilize annually if desired for vigor.
Mature Form (Years 10+)
Indefinite; 20+ year lifespanReaches full height of 15-20 feet with narrow 3-4 foot width; dense pyramid shape with consistent dark green winter color
Minimal maintenance; occasional pruning to maintain shape. No fertilizer needed unless soil is poor. Water during severe drought. Remove dead or damaged branches.
