Sowing and Growing

Sow stevia indoors in late winter and keep seeds very warm and moist. Expect low germination, which can take up to 3 weeks. Once the threat of frost has passed, harden the seedlings off, plant in full sun and keep soil evenly moist. Use mulch if stevia is growing in the ground, in order to conserve moisture. Pinch back bushy stevia plants. This herb does well in containers and can be brought inside to overwinter. Cut back flowering stems to encourage new growth.


You can start harvesting stevia leaves once plants are well established. Use fresh as a sweetener in food and drinks. However, stevia can be very sweet, so use with caution. When the growing season is over, quickly dry stevia leaves in a very low oven (below 150℉). Store whole leaves in a cool, dry area and use before the next growing season. Grind the dried leaves up as needed. Stevia supports the digestive tract with zero calories and inhibits tooth decay!
