Harvest Tips
Cut flowers early in the morning when stems are fully hydrated. Cut at a 45-degree angle just above a leaf node. Strip lower leaves below the waterline to prevent rot. Carnea blooms last 10-14 days or longer in a clean vase with floral preservative and cool conditions. For continuous harvest, deadhead spent flowers or cut stems when 1-2 flowers open for prolonged vase life.
