The Best Growing Conditions for Stevia

Stevia is an herb native to South America, but it is adaptable and is now found in many climate zones across the United States and southern Canada. It is a genus of the sunflower family, and the generic term "stevia" is typically used when referring to "stevia rebaudiana", also known as sweetleaf, sweet leaf, or sugarleaf, due to its sweet-tasting leaves. Stevia is used as a sweetener and sugar substitute.
  1. Temperature

    • The correct temperature is vital to successful stevia growth.

      Young stevia plants are tender and susceptible to damage from frost and low temperatures; it is therefore crucial to transplant them into the garden well after the danger of frost has passed. The best soil temperature is around 60 degrees Fahrenheit.

    Soil conditions

    • Adding compost to soil will add nutrients.

      Rich, loamy soil is the best growing environment for stevia plants. The plant's feeder roots are typically close to the surface of the soil, so it is wise to add compost if your soil is sandy, to give the plants as many nutrients as possible. Ensure that the soil drains well, and minimize risks of flooding; soggy soil will stop the stevia plants from thriving.

    Care

    • Light, regular watering will help stevia plants grow.

      During the summer, stevia plants should be watered frequently; a light watering will suffice. To stop the feeder roots from drying out, add compost or mulch around each individual plant. Organic fertilizer releases nitrogen slowly, which is ideal for stevia plants. Alternatively, a fertilizer with a nitrogen content lower than its phosphoric acid or potash content is suitable. If cared for properly, stevia plants can be grown indoors, with equally effective results. A spot with plenty of sunlight, or a hydroponic unit, is ideal. Alternatively an indoor container measuring 10 to 12 inches in diameter filled with a growing mix can be used for each plant.
