Guide to Growing Lilacs

Fragrant Favorites: A Guide to Growing and Enjoying Lilacs

Few plants capture the magic of spring like lilacs. Their sweet, nostalgic scent often brings back memories of home or garden strolls from seasons past. For many, the blooming of lilacs signals that summer is just around the corner. 

Growing Lilacs: Tips for Success 

☀️ Sunlight

  • Full sun (6+ hours a day) is essential for strong flowering. 

 

🌱 Soil

  • Lilacs thrive in well-drained soil. If your soil is heavy or clay-based, improve drainage by adding compost and gypsum. 
  • They also prefer a sweet soil with a PH between 6.5 and 7 and will benefit from a handful of lime worked into the soil at the base of the plant each fall. 

 

🍃 Air Circulation

  • Space plants to allow for airflow—this helps prevent powdery mildew on foliage. 

 

✂️ Pruning & Deadheading

  • Prune right after flowering, ideally by early July, to avoid cutting off next year’s blooms. 
  • Deadhead spent flower clusters to encourage future flowering and maintain shape. 

 

Where to Plant Lilacs

  • Near patios or windows, where their fragrance can drift indoors 
  • As part of a mixed border with peonies and roses 
  • In a hedge for privacy and scent 

How to Cut Lilacs for Arrangements

  • Lilacs make beautiful, fragrant cut flowers. Harvest panicles when ¼ to ½ open. Split the bottom of each woody stem 1–2 inches with pruners for better water uptake—no need to crush the stems.
