Planting & Care

Scentara® Double Blue Lilac shrubs grow best in full sun and well-drained soil. Dig a planting hole about 50 percent wider than the root ball and plant with the top of the root ball slightly above the surrounding soil line to promote good drainage. Water thoroughly after planting and maintain consistent moisture during the establishment period. Once established, lilacs are relatively low maintenance. Pruning should be done immediately after the spring bloom, since lilacs flower on old wood and pruning later may reduce next season’s flowers.
