Growth Stages

1

Establishment

4-6 weeks

Young plant with tender growth; developing root system in new container or location

Keep soil consistently moist, provide bright indirect light, maintain humidity above 50%, avoid drafts and temperature fluctuations

2

Vegetative Growth

Ongoing during spring-summer

Plant develops characteristic weeping branches with narrow, linear foliage; graceful cascading form emerges

Maintain steady moisture, provide bright indirect light, fertilize monthly during growing season, prune gently to shape

3

Active Growth Period

Spring through early fall

Vigorous expansion of foliage with new shoot development; tree reaches fuller form

Increase watering frequency, provide high humidity (mist regularly or use pebble tray), fertilize bi-weekly with balanced liquid fertilizer

4

Dormancy/Rest

Fall through early spring

Slower growth during fall and winter; foliage remains but growth rate decreases significantly

Reduce watering frequency, allow soil to dry slightly between waterings, reduce fertilizing, maintain bright light but cooler temperatures (60-70°F ideal)
