Carnation

How to care for carnation

• Light: Requires full sun, at least 6 hours of direct sunlight daily, for best flowering. Can tolerate very light shade in hot climates.
• Water: Water deeply and regularly, especially during dry spells, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry between waterings.
• Soil: Prefers well-draining, slightly alkaline to neutral soil. Amend heavy clay soils with organic matter to improve drainage.
• Temperature: Thrives in moderate temperatures between 50-75°F (10-24°C). Some varieties are hardy, while others need protection from frost.
• Humidity: Tolerates average humidity; good air circulation is more important to prevent fungal issues.
• Fertilizer: Feed with a balanced, all-purpose fertilizer every 4-6 weeks during the growing and flowering season. Avoid excessive nitrogen, which can lead to leggy growth.
• Propagation: Can be propagated by seeds, stem cuttings, or by layering. Cuttings are best taken from non-flowering shoots in late spring or summer.

Is carnation toxic to pets?

Not pet-safe. Carnations are mildly toxic to cats and dogs, causing mild gastrointestinal upset or dermatitis if ingested. See our guide to toxic plants for cats and dogs.

Common problems

• Lack of blooms/sparse flowering: Ensure full sun exposure, deadhead spent flowers regularly to encourage new blooms, and avoid over-fertilizing with nitrogen.
• Fungal diseases (e.g., rust, rot): Provide good air circulation, avoid overhead watering, and ensure well-draining soil; remove affected plant parts.

Did you know?

Carnations have been cultivated for over 2,000 years and are native to the Mediterranean region, often found growing in rocky areas.
