About Stevia
Stevia is a small herb from Paraguay whose leaves contain steviol glycosides — compounds 200–300 times sweeter than sugar but with almost no calories. It has been grown commercially in India since the 2000s, and a single pot on a sunny balcony can supply enough fresh leaves to sweeten your daily tea. Dried homegrown leaves have a faint liquorice aftertaste that refined stevia powders remove.
Botanically known as Stevia rebaudiana, it belongs to the Asteraceae family. It is native to South America and grows best in a tropical/sub-tropical climate. The parts most often used are the leaves.

How Stevia Is Used

How to Grow Stevia
| ☀️ Sunlight | Full sun; light afternoon shade in very hot areas. |
| 💧 Watering | Keep soil evenly moist but never soggy — roots rot easily. |
| 🪴 Soil | Light, sandy loam with good drainage and moderate compost. |
| 🌱 Propagation | Stem cuttings root readily; seeds have low germination rates. |
| 📅 When to plant (India) | Plant February–April or after the monsoon (September–October). |
| 🏡 In pots / at home | A 10-inch pot is enough. Pinch tips often and remove flowers to keep the leaves sweet. |
Precautions & Safety
