Planting & Care

Water your gardenia before planting and select a location receiving full sun or dappled shade. Excavate a hole twice as wide as the root ball, positioning the plant 1–2 inches above ground level, then backfill with native soil and water thoroughly. Apply 1–2 inches of mulch around the base, keeping it away from the stem. Water weekly when soil feels dry at 2 inches depth. Feed with acid-loving plant fertilizer and iron supplements in mid-March and late June to maximize blooms; skip fall feeding to prevent tender new growth. After flowering ends, prune out dead wood and leggy branches to maintain the plant's tidy, columnar silhouette.
