Stevia: Edible Plant
Stevia rebaudiana
Stevia needs a sunny location with at least 6 hours of direct light daily, consistently moist (never waterlogged), well-draining soil with a pH of 6.5–7.2, and temperatures between 7–29 °C. It does not tolerate frost or prolonged drought. Regular pinching of shoots keeps the plant compact and enhances the sweetness of the leaves.

What is Stevia?
Stevia (Stevia rebaudiana) is a medium-care plant from the Asteraceae family. Stevia (Stevia rebaudiana) is a perennial subtropical herb from the Asteraceae family, native to Paraguay and Brazil. It grows to a height of approximately 60 cm, has small ovate to elliptical leaves with a finely serrated edge, and in summer produces small white tubular flowers in racemose inflores...
Stevia grows up to 60cm, spread of 60cm, watering every 3 days, 7°C – 29°C. It is suitable for indoor environments and safe for pets.
Unlike many popular species, Stevia is safe to keep around pets. Without adequate drainage, root rot can develop within 7 days.
How to Care for Stevia?
TLDR: Stevia needs Bright indirect, watering every 3 days, and temperatures between 7-29°C with 40-70% humidity.
How Often Should You Water Stevia?
Water regularly to keep the soil consistently moist, but never waterlogged – excess water in the root ball easily leads to root rot. Water at the base of the plant to keep the leaves dry.
How Much Light Does Stevia Need?
Choose a sunny location with a minimum of 6 hours of direct sun daily. The plant will survive in partial shade, but the leaves will be less sweet, and the plant will be sparser.
What Is the Best Soil for Stevia?
Use light, well-draining soil rich in organic matter with a pH of 6.5–7.2. For heavier soils, mix in sand or perlite for better drainage.
What Pot Should You Use for Stevia?
A ceramic or terracotta pot with drainage holes and a depth of at least 30 cm to provide ample space for the root system and allow excess water to drain freely.

What Is Stevia and Where Does It Come From?
Stevia (Stevia rebaudiana) is a perennial subtropical herb from the Asteraceae family, native to Paraguay and Brazil. It grows to a height of approximately 60 cm, has small ovate to elliptical leaves with a finely serrated edge, and in summer produces small white tubular flowers in racemose inflorescences. The leaves contain steviol glycosides – a natural sweetener up to 300 times sweeter than sugar, which is why the plant is cultivated worldwide as a sugar alternative.

What Diseases Commonly Affect Stevia?
TLDR: Stevia is susceptible to 13 known diseases. Monitor regularly for early detection.
Septoria Leaf Spot
Septoria leaf spot is a destructive fungal disease caused by Septoria lycopersici, particularly devastating during seasons of moderate temperature and abundant rainfall. The disease starts on lower leaves and progresses upward, causing small circular spots with tan to gray centers and dark brown margins. If left untreated, it can dramatically reduce plant yields and cause complete leaf blight.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Alternaria Leaf Spot
Alternaria leaf spot is a common fungal disease caused by Alternaria solani and Alternaria alternata that affects a wide range of plants including tomatoes, potatoes, brassicas, and ornamentals. The disease thrives in warm, humid conditions and can cause significant crop damage if left untreated. Spores overwinter on plant debris and can attach to seeds, making complete elimination difficult.
Cercospora Leaf Spot
Cercospora leaf spot is a common fungal disease caused by Cercospora species that affects many plant types, particularly beets, roses, and leafy vegetables. The disease thrives in warm, humid conditions and can cause significant defoliation, reducing plant vigor and yield. It spreads rapidly through water splash, wind, and contaminated tools.
Meaning & Symbolism
A symbol of natural sweetness and a healthy lifestyle free from artificial substances – a gift from nature offering sweet taste without calories.
