Stevia is a natural, calorie-free sweetener derived from the leaves of the Stevia rebaudiana plant. Growing stevia indoors allows you to enjoy a fresh, organic sugar substitute while adding a beautiful green touch to your home.
1. Best Stevia Varieties for Indoor Growing
Stevia rebaudiana ‘Sweet Leaf’ – The most common variety, used for its natural sweetness.
Stevia ‘Candy’ – A sweeter variety with higher levels of steviol glycosides.
Stevia ‘Eirete’ – Compact and ideal for small indoor spaces.
2. Best Growing Conditions for Indoor Stevia
Light Requirements
Stevia requires 6–8 hours of bright, indirect sunlight. A south-facing window is best, but grow lights can be used for additional support.
Temperature and Humidity
Stevia thrives in temperatures between 65–80°F (18–27°C) and prefers moderate humidity. Avoid placing it in overly dry environments.
Choosing the Right Pot and Soil
Use a medium-sized container with drainage holes. A light, well-draining potting mix with compost or sand ensures healthy root development.
3. Watering and Fertilizing Indoor Stevia
How Often to Water
Water stevia when the top inch of soil feels dry. Keep the soil evenly moist but not soggy to prevent root rot.
Fertilizing for Healthy Growth
Feed stevia with a diluted organic fertilizer every 6–8 weeks. Too much fertilizer can reduce the plant’s natural sweetness.
4. Pruning and Harvesting Stevia
How to Prune Stevia
Trim back stems regularly to promote bushy growth. Remove flower buds to extend the plant’s lifespan and keep leaves sweet.
Harvesting Stevia Leaves
Pick fresh leaves as needed, but for the best flavor, harvest just before flowering. Dry leaves and grind them into a natural sweetener.
