Why grow Stevia at home?
El home cultivation of Stevia It is much more than a trend: allows you to have fresh leaves to sweeten beverages, dry them for infusions, or use them in sweet and savory recipes.

Regular consumption of Stevia is especially indicated for people with diabetes, hypertension or obesity and is used as support in skin treatments and states of fatigue.
How to grow Stevia at home step by step
Stevia It can be grown both by seed and by cuttingsAlthough sowing from seed is possible, propagation by cuttings is much simpler and more effective for beginners, ensuring plants with the best properties.
Cultivation by seeds
- Prepare the pot: Fill a pot with moist peat moss. Stevia seeds are very small and require light to germinate, so don't cover them with soil; just press them gently into the soil.
- Conditions for germination: Place the pot in a bright location but not in direct sunlight. Keep the soil moist, taking care not to wash the seeds away when watering. Germination can take between one and four weeks, and the ideal temperature is around 20-22°C.
- Transplant: After three months, when the roots emerge from the base of the pot, transplant each seedling into a larger pot with a substrate enriched with humus.
Cultivation by cuttings
- Obtaining the cutting: Cut the last 10 cm of a healthy shoot, removing the lower leaves.
- Plantation: Place the cutting in moist peat, pressing the substrate around the stem.
- Conditions: Place in a shady location and water about three times a day until the plant develops roots and begins to grow vigorously; after that, daily watering will be sufficient.
- Transplant: When the plant is robust, transplant it to a larger pot or to the garden with a separation of 60 cm between plants.
Soil and climate requirements
Stevia prefers acidic soils (pH between 6 and 6,5), rich in organic matter and with good drainage. It is essential to use peat substrate enriched with humus and add worm humus each spring, usually 20% of the container's volume.
In subtropical and warm climates, Stevia is a perennial. In regions with cold winters, it is grown as an annual or protected indoors during the winter, keeping it protected from frost.
- Light: It needs good light, but it is advisable to avoid direct sunlight in summer (especially in warm areas), using shade nets if necessary.
- Temperature: Its optimal range is around 24ºC and requires protection against sudden drops.
Frequent watering, humidity and care
Stevia needs environmental humidity, especially in dry climates. In spring and autumn, watering every 2-3 days is sufficient, but in summer it will be necessary daily watering and even increase the frequency on windy or very hot days. Spraying water into the air helps maintain humidity in arid areas.
Avoiding overwatering is essential because the roots are very shallow and can rot if the substrate remains soggy. A layer of compost around the stem can help retain moisture and provide additional nutrients.
Pruning and harvesting Stevia
La pruning and harvesting Harvesting should be done just before flowering, when the stevioside concentration is highest. Cut the branches to about 5 cm above the soil or substrate. The best time to harvest is in the morning, when the plants are at their sweetest.
- Drying the leaves: Avoid direct sunlight to preserve its properties. Choose dark, well-ventilated areas or use a dehydrator or oven at low temperatures.
- Conservation: Store the dried leaves in airtight containers, preferably glass, to maintain their sweetness for years.
- Use: You can grind the dried leaves by hand or using a grinder until you obtain a fine powder that can be used for infusions or to sweeten your favorite recipes. One whole leaf is enough to sweeten a cup of tea.
Reproduction and maintenance of the plant
You can multiply your Stevia plants each year through cuttings and divisions, avoiding flowering cuttings, as they tend not to root. Older plants (from the third year onward) lose productivity, so it's recommended to replace them periodically.
Pests, diseases and common problems
Stevia is resistant to most diseases, but can be affected by:
- Chlorosis: If the substrate is not acidic enough, the leaves turn yellow.
- Common pests: Ants, snails, and slugs. To control them, use ecological solutions such as diatomaceous earth, traps or iron phosphate.
Don't use chemicals on plants intended for consumption. Organic management is always the best option.
How to use Stevia in the kitchen
Stevia can be used fresh or dried in infusions, and in powder form in baked goods or cooked dishes. Homemade sweetener extraction is done by infusing lightly crushed leaves in hot water, filtering the mixture, and storing the liquid in the refrigerator for one or two weeks. Remember that intensity of sweetness varies Leaf by leaf. As a guide, 3-4 teaspoons of green Stevia powder can replace one cup of sugar in recipes, but the characteristic licorice flavor should be taken into account.
The dried leaves, when finely ground, remain sweet for years if stored properly, offering a healthy and practical alternative in everyday cooking.
Growing Stevia at home is a rewarding experience: the plant not only provides a high-quality natural sweetener, but it also enriches the home with its beauty and multiple health benefits. With proper care, you can enjoy its fresh or dried leaves year-round, incorporating them into your diet and improving your quality of life in a healthy and sustainable way.
