Growth Stages

1

Seedling

4-8 weeks

Young plant with developing cotyledons and initial true leaves; delicate growth

Keep soil consistently moist but not waterlogged; provide bright indirect light; protect from strong winds and harsh sun

2

Vegetative Growth

1-2 years

Rapid stem and leaf development; plant builds strong root system and canopy structure

Water regularly during growing season; provide support stake if needed; prune to encourage branching; apply balanced fertilizer monthly

3

Maturation

1-3 years

Tree establishes woody trunk and develops full canopy; may begin flowering in late stage

Reduce fertilizer frequency; water during dry periods; shape canopy through selective pruning; trees mature faster in ideal conditions

4

Flowering

4-8 weeks

Brilliant orange-red clustered flowers (racemes) cover branches before or concurrent with leaf emergence in spring

Ensure adequate sun exposure for maximum bloom; maintain moderate moisture; deadhead spent flowers if desired; minimal pruning during bloom

5

Fruiting & Maturity

3-4 months

Small, flat brown pods develop after flowering; tree enters dormancy period in dry/cool seasons

Allow pods to mature naturally if seeds desired; reduce watering and nutrients during dormancy; clean up fallen foliage
