Iron Chlorosis in Lilac: Dark Veins, Pale Leaves—Quick Fix with Ironite

Dark green veins with yellowing between them (interveinal chlorosis) on your lilac indicate iron deficiency, a common issue for lilacs and gardenias.

Treatment

Apply Ironite (available as granules or foliar spray). The spray works faster—apply directly to foliage for quick greening. Results are usually visible within days.

Why It Happens

High soil pH ties up iron, making it unavailable to the plant. Lilacs are especially sensitive. Annual or seasonal iron supplementation prevents recurrence.
