Ask ChatGPT: How to grow carnations indoors?

As the carnation is recognized as the birth flower for January, I’m interested in learning more about it as a beginner.

Carnations are very popular with their big, ruffled petals and beautiful colours, and they’re especially perfect as gifts for January babies. Also, they’re one of the very few flowers that thrive in winter!

While the meaning of carnations can change depending on the colour, generally they symbolize devotion, loyalty and love.


Growing carnations indoors can be a rewarding experience, allowing you to enjoy their beautiful blooms year-round. Here’s a guide on how to grow carnations indoors:


1. Choose the Right Variety:

There are various types of carnations, including border carnations, perpetual flowering carnations, and dwarf carnations. Choose a variety that suits your preferences and climate. Select a variety of carnation that is well-suited for indoor cultivation. 

2. Container and Soil:

Use well-draining potting soil with a slightly acidic to neutral pH. Choose a container with drainage holes to prevent waterlogging.

3. Planting:

Plant seeds or small seedlings in the prepared container. Place the seeds or seedlings at the recommended depth on the seed packet or plant tag.

4. Sunlight:

Carnations thrive in full sunlight. Place the container in a location where the plant receives at least 4-6 hours of direct sunlight each day. If natural light is insufficient, supplement with a grow light.

5. Temperature:

Maintain a moderate room temperature for your indoor carnations, ideally between 60-70°F (15-21°C). Avoid exposing them to extreme temperature fluctuations.

6. Watering:

Keep the soil consistently moist but not waterlogged. Water the plant at the base to prevent the foliage from getting wet. Allow the top inch of soil to dry out slightly between watering

7. Humidity:

Carnations prefer moderate humidity. If your indoor environment is too dry, consider placing a humidity tray filled with water and pebbles near the plant to increase moisture in the air.

8. Pruning & Support

Pinch back the growing tips regularly to encourage bushier growth and more flower buds. Remove spent flowers to promote continuous blooming.

If your indoor carnations grow tall and become top-heavy, provide support with stakes to prevent bending or breakage.

9. Pest Management:

Keep an eye out for common indoor pests such as aphids or spider mites. Treat any infestations promptly with appropriate measures, such as insecticidal soap.

10. Winter Care:

Indoor carnations may not have a true dormant period, so continue regular care throughout the year. If you notice a decline in growth during the winter, it might be due to lower light levels.

By providing the right conditions, you can successfully grow carnations indoors and enjoy their colorful blooms throughout the year. Adjust care based on the specific needs of the variety you choose, and enjoy the beauty and fragrance of indoor-grown carnations.
