Planting & Care

Caring for the Scentara® Double Blue Lilac involves understanding its specific planting and maintenance requirements to ensure it thrives and provides the best display of blooms and fragrance.


  1. Timing: Plant in early spring or fall. Avoid planting in extreme heat or cold.
  2. Location: Choose a location with full sun (at least 6 hours of direct sunlight daily, with 8 or more being ideal).
  3. Soil: Prefers well-drained, alkaline soil. Lilacs are adaptable to various soil types, but poor drainage can be detrimental.
  4. Planting Depth and Spacing: Dig a hole as deep as the root ball and twice as wide. Space plants 6 to 8 feet apart to allow for growth and air circulation.
  5. Watering after Planting: Water thoroughly after planting. Ensure the soil is moist but not waterlogged.


  1. Sunlight: Full sun is crucial for optimal growth and blooming.
  2. Watering: Water the plant deeply but infrequently. The soil should never be soggy. Lilacs require less water once established but may need more during extreme heat.
  3. Mulching: Apply mulch around the base to retain moisture and regulate soil temperature.
  4. Fertilizing: Use a balanced fertilizer in early spring, but avoid over-fertilizing, which can lead to more foliage and fewer blooms.
  5. Pruning: Prune immediately after blooming if necessary. Pruning later can remove the next season's flower buds. Remove any dead or diseased branches and thin out as needed to encourage airflow.
  6. Disease and Pest Control: Scentara® Double Blue is generally disease-resistant. Keep an eye out for common lilac pests and diseases, treating them as needed.
  7. Winter Care: In colder climates, lilacs typically do not require extra winter protection. However, in borderline hardy zones, a layer of mulch can help protect the roots.
  8. Soil pH: If your soil is not naturally alkaline, consider using soil amendments to adjust the pH level.
  9. Rejuvenation: Older lilacs can benefit from rejuvenation pruning to restore vigor and bloom quality.

Additional Tips:

  • Cold Tolerance: Lilacs need a period of cold dormancy. They are more cold tolerant than heat tolerant.
  • Bloom Requirement: Ensure they receive a minimum of 1,700 hours of temperatures below 45°F (7.2°C) for adequate bloom.
  • Avoiding Root Rot: Ensure good drainage to prevent root rot, particularly in winter.

By following these planting and care guidelines, your Scentara® Double Blue Lilac should thrive, providing beautiful blooms and a delightful fragrance for many years.
