Growth Stages

1

Establishment

3-6 months

Young transplant with developing root system and compact foliage

Water regularly but allow soil to dry slightly between waterings. Protect from extreme heat and cold. Avoid fertilizer in first 3-6 months.

2

Vegetative Growth

6-12 months

Plant develops dense, bushy form with needle-like leaves; minimal flowering

Light pruning after flowering to maintain shape. Ensure good air circulation. Water moderately; reduce in summer months.

3

Bud Formation

2-3 months

Small flower buds develop along stems in late autumn; foliage remains evergreen

Maintain consistent watering; buds are sensitive to drought stress. Avoid late-season nitrogen fertilizers.

4

Flowering

6-10 weeks

Abundant tubular flowers in shades of red, pink, or bicolor; peak display in winter to early spring

Continue regular watering. Deadhead spent flowers to encourage extended blooming. Avoid moving plant during flowering.

5

Post-Flowering

4-6 weeks

Flowers fade and seed capsules develop; plant prepares for dormancy in late spring

Prune lightly to shape plant and encourage bushiness. Reduce watering gradually as temperatures warm.
