Seedling
3-4 weeksTiny seedlings with cotyledons and first true leaves emerge; very delicate with minimal foliar coverage
Maintain consistent moisture without waterlogging; provide bright light; keep in warm environment (70-75°F); protect from damping off with good air circulation
Juvenile
6-12 monthsYoung plant develops characteristic silvery-grey foliage and establishes main stem; growth accelerates with increasing leaf area
Reduce watering frequency as drought tolerance develops; ensure full sun exposure; apply light fertilizer monthly during growing season; stake if necessary for support
Establishment
1-3 yearsTree develops stronger branch structure and increases in height; bark begins to darken and thicken; root system expands significantly
Continue regular watering for first 2 years; prune lower branches to shape; reduce fertilization; mulch lightly to retain moisture but keep away from trunk
Mature
Ongoing (10+ years)Tree reaches ornamental size (15-25m) with dark, thick bark and established canopy; minimal need for supplemental care
Rarely needs watering except in drought; prune only for structural integrity or disease removal; monitor for pests; no fertilization needed
