Frost can damage lilacs, especially if it occurs after the buds have started to open in spring. Early spring frosts may cause the flowers to wilt or drop prematurely, but established lilac plants are generally resilient and can survive light frosts. If the frost is severe or prolonged, it could potentially harm the plant's overall health. Protecting lilacs with covers or mulch during unexpected frosts can help mitigate damage.
