Planting & Growing Guide:
- Plant Spacing: Space mature plants 10–12 inches apart to ensure proper air circulation and full, bushy growth.
- Seeds Per Foot: Sow approximately 3–4 seeds per foot in garden beds, thinning to 1 plant every 10–12 inches once seedlings are well-established.

|
Season |
Action |
|
Early Spring |
Start seeds indoors 6–8 weeks before your local last frost date to get a head start on blooms. |
|
Late Spring |
Transplant seedlings outdoors after all frost danger has passed. Direct-sow seeds in warm, frost-free climates. |
|
Summer |
Keep soil evenly moist; deadhead spent blooms regularly to encourage continuous flowering and extend the bloom season. |
|
Fall |
Mulch plants in zones 3–6 to protect roots from freezing temperatures. In warmer zones, plants may remain evergreen through winter. |
- Germination: 14–21 days at 60–70°F (15–21°C). Sow seeds 1/8 inch deep in well-drained, fertile soil with full sun (6+ hours daily).
- Watering: Water moderately, allowing the top 1–2 inches of soil to dry between waterings to prevent root rot. Carnations prefer slightly dry conditions over soggy soil.
- Fertilizing: Feed with a balanced, all-purpose fertilizer every 4–6 weeks during the growing season to promote lush foliage and abundant, vibrant blooms.
