Stevia, a South American herb known for its sweetness, is challenging to germinate but grows in warm climates, making it ideal for summer containers and gardens. A simple guide on growing Stevia from seed is provided.
Stevia belongs to the family Asteraceae and is scientifically known as Stevia rebaudiana. It’s more commonly referred to as Sweetleaf due to its intensely sweet leaves.
Begin your Stevia cultivation indoors, ideally 8-10 weeks before the last frost date, to give the plants a good start. The seeds require a specific set of conditions to germinate—bright light and consistent warmth are crucial.
It's advisable to place the seeds on the surface of a damp, sterile seed mix and use a heat mat to maintain an optimal temperature. Be patient, as germination can be slow and may take between 10 and 16 days.
Stevia is like basil, thrives in well-drained soil and requires ample sunlight. In hot climates, providing some afternoon shade can help protect the plants. It's important to water regularly, especially in dry conditions, to maintain healthy growth.
For a bushier and more productive plant, pinch back the growing tips once or twice throughout the growing season. Ensure to space the plants approximately 60 cm (24 inches) apart to allow sufficient room for them to flourish.
Stevia can be harvested throughout the summer. The leaves, which are the source of its sweetness, can be clipped as needed. These leaves dry well and can be used as a low-calorie sweetener throughout the fall and winter.
Additional Tips: Growing Stevia is more about managing the early stages of germination. Once the plants are established, they are relatively low maintenance. Consider Stevia not only as a sweetener but as a sustainable addition to your garden that offers both aesthetic and practical benefits.
By following these steps, you can successfully grow Stevia in your own garden, enjoying the sweet rewards of your efforts in a natural and healthy way. Start planting today and sweeten your dishes with your home-grown Stevia!
