Growing Snapdragons Indoors: A Guide to Captivating Indoor Gardens

Indoor gardening has become increasingly popular among plant enthusiasts, and one fascinating flower that can add a touch of vibrancy and elegance to your indoor space is the snapdragon (Antirrhinum majus). Known for their striking colors and distinctive shape, snapdragons can thrive indoors with proper care and attention. This article serves as a comprehensive guide to growing snapdragons indoors, offering valuable insights into the ideal conditions, essential care practices, propagation methods, and troubleshooting tips.

Choosing the Right Snapdragons for Indoor Cultivation

Snapdragons come in a variety of sizes and colours, making them an ideal choice for indoor cultivation. When selecting snapdragon varieties, consider dwarf or compact cultivars that are better suited for indoor containers. Popular snapdragon varieties suitable for indoor growth include the Liberty Series, Floral Showers, and the Montego Series.

Creating the Ideal Growing Environment

Snapdragons require specific environmental conditions to flourish indoors. Adequate lighting is crucial for their growth, so place your plants in a bright spot near a south or west-facing window. If natural light is limited, consider using supplemental artificial grow lights to ensure they receive at least 12-16 hours of light daily. Snapdragons also thrive in temperatures between 60°F and 75°F (15°C to 24°C), so avoid placing them in drafty or excessively hot areas.

Selecting the Right Containers and Soil

Choose well-draining containers that are at least 6-8 inches (15-20 centimetres) deep, allowing the roots to grow comfortably. Terra cotta or plastic pots with drainage holes are ideal. Opt for a well-balanced potting mix with good drainage properties, such as a mixture of peat moss, perlite, and compost. Avoid using heavy garden soil, as it can impede drainage and lead to root rot.

Watering and Fertilising Practices

Snapdragons prefer evenly moist soil, but overwatering can cause root rot. Water the plants when the top inch of the soil feels dry, and ensure the excess water drains out of the container. Avoid watering the foliage to prevent fungal diseases. Fertilise snapdragons every two weeks during the growing season using a balanced liquid fertiliser. Dilute the fertiliser according to the package instructions to avoid overfeeding, which can result in leggy growth.

Propagation Techniques

Snapdragons can be propagated through both seeds and stem cuttings. To grow snapdragons from seeds, sow them in a seed-starting mix indoors 8-10 weeks before the last frost date. Keep the soil consistently moist and provide ample light. For stem cuttings, take 3-4 inch (7-10 centimetres) cuttings from healthy snapdragon plants, remove the lower leaves, and place them in a rooting hormone. Insert the cuttings in a moist soilless mix and provide bottom heat to encourage root development.

Common Challenges and Troubleshooting

Indoor snapdragons are susceptible to pests such as aphids, spider mites, and whiteflies. Regularly inspect your plants and take prompt action if pests are detected, using organic pest control methods whenever possible. Additionally, watch out for signs of fungal diseases like powdery mildew or root rot. Maintain proper air circulation and avoid overhead watering to prevent such issues. Lastly, monitor your plants for any signs of nutrient deficiencies and adjust your fertilisation routine accordingly.


Growing snapdragons indoors can be a rewarding experience, offering a burst of colour and charm to your living space. By providing the right growing conditions, choosing suitable varieties, and implementing proper care practices, you can successfully cultivate these enchanting flowers indoors. Experiment with different snapdragon varieties, arrange them in containers of varying heights and colours, and witness the beauty they bring to your indoor garden. With patience and dedication, you can enjoy the delightful presence of snapdragons all year round. Happy gardening!
