Growth Stages

1

Establishment

First 12 months

Young plant focuses on root development with modest foliage growth; may produce few or no flowers in first year

Keep soil consistently moist. Mulch heavily around base. Avoid fertilizing heavily in first year. Protect from harsh winds.

2

Vegetative Growth

Year 2-3

Plant develops dense branching structure with elliptic, deciduous leaves; increases in height and width

Pinch back new growth in early summer to encourage bushiness. Deadhead spent flowers to redirect energy. Maintain consistent watering schedule.

3

Flowering

2-3 weeks in May

Profuse apricot-pink, fragrant trumpet-shaped flowers with yellow blotch appear in clusters on branch tips in mid-to-late spring

Minimal fertilizer needed if soil is rich in organic matter. Deadhead faded flowers promptly. Enjoy the 2-3 week bloom period.

4

Post-Bloom Growth

June-August

After flowering, new foliage emerges vigorously; plant continues branching and gaining structure through summer

Light pruning if needed to maintain shape. Continue watering during dry periods. Apply balanced fertilizer sparingly if desired.

5

Dormancy

September-April

Deciduous foliage transitions to attractive autumn colors (burgundy, orange) before dropping; bare branches remain ornamental through winter

Reduce watering as plant enters dormancy. Apply mulch to protect roots in cold zones. No pruning needed unless removing damaged wood.

  • Increase humidity by misting foliage; spray with water to dislodge; use miticide if severe

  • Ensure excellent drainage; avoid overwatering; improve air circulation; apply fungicide drench if detected early

  • Improve air circulation; remove affected leaves; apply sulfur or fungicide if needed

  • Remove infected leaves and shoots before spores spread; improve drainage and air circulation

Fun Facts

  • 🌱 The Exbury Hybrid azaleas were developed in the 1930s by Lionel de Rothschild at Exbury House in England, and are considered among the finest deciduous azaleas for their size, fragrance, and color range.
  • 🌱 Deciduous azaleas are more fragrant than evergreen azaleas, and Exbury Cecile's sweet apricot scent is especially pronounced on warm spring days, sometimes releasing fragrance across an entire garden.
  • 🌱 The name 'Cecile' is one of the Exbury Hybrid cultivars named after family members; the apricot-pink color was a breakthrough achievement in the 1930s breeding program, as this soft peachy tone was previously rare in azaleas.
