Seedling
2-3 weeksTiny green shoots emerge with cotyledons (seed leaves). Plant develops first true leaves.
Keep soil consistently moist but not soggy. Provide bright light and maintain 65-70°F temperature. Thin seedlings when 1 inch tall.
Vegetative Growth
4-6 weeksPlant develops multiple stems and lance-shaped blue-green foliage. Bushy mounding form begins to take shape.
Pinch growing tips at 4-6 inches tall to encourage branching and fuller shape. Water regularly and maintain good air circulation. Feed with balanced fertilizer every 2-3 weeks.
Flowering
6-10 weeks (continuous if deadheaded)Flower buds form at stem tips, swelling and developing color. Blooms open with characteristic ruffled petals in various colors with sweet fragrance.
Deadhead spent blooms to encourage continued flowering. Provide full sun and maintain consistent watering. Support tall varieties with stakes if needed.
Peak Production
8-12 weeks or morePlant in full, abundant bloom with multiple flowers at various stages of opening.
Continue deadheading. Feed with phosphorus-rich fertilizer to support blooming. Cut flowers for arrangements to stimulate more blooms. Monitor for pests and disease.
Decline/Winter Dormancy
SeasonalFlowering slows as temperatures cool. Plant may go dormant in cold climates; semi-evergreen foliage remains in mild zones.
Reduce watering in dormant season. Cut back stems in spring before new growth. In zones 3-5, provide mulch protection over winter. In zones 6+, plants often overwinter with minimal protection.

Harvest Tips
Cut flowers in early morning when stems are turgid. Choose blooms that are just opening with loose petals. Cut at 45-degree angle above a node. Remove lower foliage below the waterline. Carnations last 2-3 weeks in a vase with fresh, cool water changed every 2-3 days. For garden display, deadhead regularly to extend blooming season through fall.
