Growing snapdragons indoors can be a rewarding endeavor, and with the right conditions, you can enjoy their vibrant blooms. Here are some tips to help you succeed:
Soil: Snapdragons prefer well-draining soil, rich in organic matter. A high-quality potting mix with added perlite or sand can improve drainage, which is crucial to avoid root rot. They thrive in slightly acidic to neutral soil, with a pH of around 6.2 to 7.0.
Watering: Consistent moisture is key for snapdragons, but be careful not to overwater, as soggy soil can lead to root issues. Water when the top inch of the soil feels dry, ensuring good drainage from the pot. It’s a balance—too little water can cause wilting, while too much can lead to disease.
Light: Snapdragons need plenty of sunlight to grow well indoors. A bright, south-facing window is ideal. They require at least six hours of direct sunlight each day. If natural light is limited, consider supplementing with a full-spectrum grow light to ensure they receive adequate light intensity.
Temperature: Snapdragons prefer cooler temperatures, ranging from 60°F to 75°F (15°C to 24°C). Keep them away from heat sources and cooling drafts to maintain a stable environment.
If you're planning to use snapdragons as cut flowers, you'll be pleased to know they generally last quite well in arrangements. They can stay fresh for about a week to 10 days if kept in clean water and a cool location. Remove any leaves below the water line to prevent bacterial growth.
