- Temperature: Average room temperature 60-80°F (15-27°C). Protect from cold drafts and temperatures below 50°F.
- Fertilizer: Feed with a balanced liquid fertilizer once or twice during the growing season (spring/summer).
- Repotting: Repot every 2-3 years or when rootbound. Use a pot with drainage holes.
How Snake Plant Purifies Air: Scientific Backing
The NASA Clean Air Study found that snake plants can remove up to 47% of common airborne toxins in 24 hours. They absorb toxins through their leaves and convert them into harmless substances. Additionally, they release moisture vapor, which can help reduce airborne allergens and dust. This makes them an excellent choice for homes, offices, and any indoor space where air quality is a concern.
For even better indoor air quality, consider pairing your snake plant with other indoor plants for air purifying and low-maintenance care.
