Establishment
4-6 monthsYoung plant with developing root system and dense, dark green foliage; compact mounded form emerging
Water regularly and consistently. Apply 2-3 inches of mulch around base, keeping clear of stem. Shelter from wind and hot afternoon sun.
Vegetative Growth
Year 1-2Plant fills out, foliage becomes denser and more lustrous. Stems thicken and branch structure solidifies.
Maintain consistent moisture and partial shade. No pruning needed unless shaping desired. Feed with balanced, acidic-loving plant fertilizer in spring.
Flowering
6-8 weeks (March-May)Fragrant, creamy-white to pale yellow flower panicles appear in dense clusters along stem tips in March-May
Peak fragrance occurs in morning. Deadheading not necessary but can promote neatness. Flowers are a major ornamental feature and attract pollinators.
Post-Flowering
6-7 months (May-November)Flowers fade; plant returns focus to foliage. Dark green leaves provide the main ornamental interest for remainder of year.
Remove spent flower panicles if desired for tidiness. Continue regular watering and feeding with balanced, slow-release fertilizer.
Dormancy/Winter
December-FebruaryPlant enters semi-dormant state; growth slows but evergreen foliage remains attractive year-round. Foliage may develop purple tints in cold weather.
Reduce watering slightly but maintain consistent moisture. Provide windbreak protection in colder zones. No supplemental feeding needed.

Common Pests
-
Inspect foliage regularly, especially leaf undersides. Prune affected branches if heavy infestation. Spray with horticultural oil in early spring (pre-bud break) or use insecticidal soap. Encourage natural predators like ladybugs.
-
Improve air circulation by spacing shrubs appropriately and pruning lower branches lightly. Remove and dispose of affected foliage. Avoid overhead watering; water at soil level. Apply fungicide in severe cases.
-
More common in hot, dry conditions. Increase humidity by misting foliage. Spray with horticultural oil or miticide if population becomes significant. Maintain consistent soil moisture.
-
Use yellow sticky traps for monitoring. Prune heavily infested foliage. Spray with insecticidal soap or neem oil. Encourage beneficial insects.
