Growth Stages

1

Establishment

3-6 months

Young plant has limited foliage and small root system; may appear stressed after transplanting

Water regularly (every 2-3 days in dry weather); mulch around base; avoid heavy pruning; protect from harsh winds if possible

2

Vegetative Growth

Several months to years depending on variety

Plant develops dense, compact branching with glossy green leaves; no flowers yet

Maintain consistent moisture; begin light pruning to shape if desired; fertilize monthly during growing season (spring-summer) with balanced fertilizer

3

Maturation

Ongoing maintenance phase

Plant reaches desired shape and size with full canopy of dense foliage; may produce small inconspicuous flowers

Prune to maintain shape; fertilize 2-3 times yearly; monitor for pests and diseases; reduce watering frequency if established

4

Flowering

2-4 weeks in spring

Small, greenish-white inconspicuous flowers appear in spring (not the main ornamental feature)

No special care needed; flowers are insignificant and do not detract from foliage beauty

5

Fruiting

Several months into fall

Small ornamental berries may develop after flowering, turning pink to red (minor feature; often removed by pruning)

Allow to remain for bird food or remove during pruning if desired; no special care required
