How to Grow Stevia (genus)

Overview

Stevia, a genus of about 240 species, is a fascinating plant native to subtropical and tropical regions across the Americas. While many Stevia species exist, it's Stevia rebaudiana that captures our attention due to its remarkable sweet leaves. These are not just any sweet leaves; they contain compounds much sweeter than sugar but with no calories, making them a popular natural sugar substitute known as stevia or by various trade names.

Growing Conditions

Stevia thrives in conditions mirroring its native lands - sunny and warm. It's drought-tolerant, making it an excellent choice for those looking to minimize water usage. The plant prefers well-drained soil with a pH between 6.0 and 8.5. While Stevia rebaudiana can be grown in pots or the ground, remember that larger quantities of leaves are easier to harvest when planted directly into the garden.

Planting & Care

Planting Stevia is straightforward. Start seeds indoors about six weeks before the last expected frost date. Transplant seedlings outdoors after the danger of frost has passed and they've outgrown their initial containers. Space plants 2-4 feet apart, depending on the variety's size. Water deeply but infrequently - aim for the soil to dry out between waterings. Stevia doesn't require much care beyond these basics; its hardiness shines in neglect.

Common Problems

Stevia is generally disease and pest-resistant, making it a low-maintenance addition to any garden. Overwatering or overly rich soil can lead to leaf yellowing and reduced sweetness, so maintain the balance for optimal health and flavor. Watch for signs of insect pests; if spotted, a quick rinse under the hose often solves minor infestations.

Harvest or Enjoy

Harvest leaves as needed throughout the growing season, typically starting about 12 weeks after planting for indoor-grown seedlings. For maximum sweetness, harvest in the morning on dry days. If you prefer to let your plant mature, cut stems just above soil level when
