-
Direct sow carnation seeds outdoors after the last frost date when soil temperatures have warmed to at least 55°F. This is typically in late spring, around late April to early May in Zone 5.
-
Choose a sunny spot with well-draining soil. Carnations prefer slightly alkaline soil but can adapt to various soil types as long as they drain well.
-
Water regularly but avoid waterlogging. Fertilize with a balanced, all-purpose fertilizer every 4-6 weeks during the growing season. Pinch back spent blooms to encourage more flowers and promote bushier growth.
