Stevia rebaudiana

How to Grow Stevia rebaudiana

Overview

Stevia rebaudiana, also known as candyleaf, sweetleaf, or sugarleaf, is a remarkable plant that offers a natural alternative to sugar. Its leaves contain compounds that can be used to create a sweet-tasting extract, stevioside, which has virtually no calories and is up to 300 times sweeter than sugar.

Growing Conditions

Stevia rebaudiana thrives in full sun and well-drained soil with a pH between 6.0 and 8.5. It is drought-tolerant but prefers moderate watering, especially during the flowering stage. The plant grows best in temperatures between 68°F and 86°F (20°C to 30°C) and can be grown in containers or directly sown outdoors.

Planting & Care

Sow Stevia seeds indoors 6-8 weeks before the last expected frost date. Transplant seedlings outside after the danger of frost has passed, spacing them about 18 inches apart. Water regularly during dry spells, but avoid overwatering. Pruning can help maintain plant size and encourage bushier growth.

Common Problems

Pests are rarely a problem for Stevia plants, but watch for aphids, whiteflies, or spider mites if you notice any discoloration or stunted growth. If your plants are too wet, they may develop root rot or powdery mildew. Ensure good air circulation and avoid overwatering to prevent these issues.

Harvest or Enjoy

Harvest Stevia leaves when they are young and tender for the best flavor. Pinch off a few outer leaves about 6-8 weeks after planting. As your plant matures, you can begin harvesting larger quantities of leaves. Dry or freeze surplus leaves for future use.
