2

Vegetative Growth

6-12 months

Plant develops characteristic lobed, serrated leaves and establishes a bushy growth habit with increasing stems

Reduce watering frequency as root system deepens. Light pruning to encourage bushiness. Monitor for pests.

3

Flowering Initiation

2-4 weeks before full bloom

Plant reaches maturity and begins producing flower buds; golden flower heads develop

Maintain established watering schedule. Avoid nitrogen-rich fertilizers which delay flowering. Provide full sun exposure.

4

Flowering & Bloom

Flowers fade; seed development occurs; plant enters a more dormant phase in hot/dry seasons

Light pruning to maintain shape and remove dead wood. Minimal watering except during drought stress. Allow some flowers to mature for seed.
