Growth Stages

1

Establishment

First 12 months

Young plant with developing root system and compact foliage; minimal flowering in first year

Water regularly; protect from wind; mulch with 2-3 inches of pine bark; avoid fertilizing excessively

2

Vegetative Growth

Year 2-4

Plant develops dense, bushy foliage with dark green waxy leaves; gradually increases in size

Maintain consistent moisture; apply light pruning after flowering if needed; feed with acid-loving plant fertilizer in spring

3

Pre-Flowering

Late summer to early winter

Plant becomes established with mature branch structure; leaf buds begin forming in late summer/fall

Reduce nitrogen fertilizer; ensure adequate phosphorus and potassium; continue consistent watering

4

Flowering

April-May depending on zone

Produces abundant white flowers with pale pink edges and undertones, arranged in tight trusses; blooms last 2-3 weeks

Do not deadhead if seed production desired; support branches if heavy with blooms; continue watering

5

Post-Flowering

Late May-June

Flowers fade; seed pods may develop; plant enters new growth phase with fresh foliage

Deadhead spent flowers if desired to redirect energy; prune only if necessary; resume light feeding
