Growth Stages

1

Establishment

2-4 weeks

Young plant settling in with initial root development; may show leaf stress or slow growth

Water regularly to keep soil moist; provide afternoon shade first 2-3 weeks; avoid fertilizing; mulch around base

2

Vegetative Growth

4-8 weeks

Plant develops dense foliage and branch structure; new leaves emerge regularly; no flowers yet

Begin balanced fertilizing monthly; pinch back tips to encourage bushiness; maintain consistent moisture; prune any dead wood

3

Flowering

4-6 months (spring through fall in tropical climates; may flower year-round in frost-free zones)

Small, star-shaped golden-yellow flowers appear in dense terminal clusters; blooms are very showy and fragrant

Apply flowering fertilizer (higher phosphorus) every 2-3 weeks; deadhead spent flower clusters to encourage continuous blooming; maintain consistent watering

4

Peak Production

Ongoing in established plants

Mature shrub with abundant flowering; dense canopy provides shade and habitat; plant reaches full size (4-6 feet tall)

Fertilize every 3-4 weeks during growing season; prune after heavy flowering to maintain shape; watch for pest infestations in heat

5

Winter Dormancy

2-3 months (minimal in tropical zones)

Growth slows significantly; flowering decreases in cooler climates; foliage may thin slightly

Reduce watering frequency; stop or reduce fertilizing; prune lightly to maintain shape; protect from frost in zone 9b
