Did You Know?
1. Stevia, also known as “sweet leaf” or “sugar leaf,” is a native plant to South America, primarily found in Paraguay and Brazil.
2. Despite being incredibly sweet, stevia has zero calories and is up to 200 times sweeter than regular sugar, making it an ideal sugar substitute for those looking to reduce their calorie intake.
3. Stevia leaves have been used for centuries as a natural sweetener by the Guarani people of South America, who chewed the leaves or made teas from them to enhance the taste of food and beverages.
4. The active compounds responsible for stevia’s sweetness, known as steviol glycosides, are found in the leaves of the plant. These compounds are extracted through a process of harvesting the leaves, drying them, and then steeping them in water to release the sweetness.
5. When harvesting stevia, it is best to pick the plant’s mature leaves, as they have higher concentrations of the sweetening compounds. These leaves can then be used fresh or dried for further processing and storage.
Stevia Harvesting Methods
Stevia, with its sweet and green leaves, is a popular herb used as a sugar substitute. Harvesting stevia involves several methods. The most common approach is to harvest the leaves for immediate use or drying. Stevia leaves can be used fresh, dried, powdered, or even in liquid form to sweeten food and beverages.
To harvest stevia leaves, begin by carefully trimming off the fully developed leaves at the stem using a pair of sharp scissors or pruning shears. It is recommended to start harvesting when the plant reaches a height of at least 8 inches. By trimming the plant back, you encourage outward growth and stimulate the production of more leaves.
If you intend to use stevia leaves fresh, simply wash them thoroughly and remove any excess moisture before applying them to your desired recipe. On the other hand, if you plan to dry the leaves for later use, you can hang the trimmed stems upside down in a cool, dark, and well-ventilated area. Once fully dried, separate the leaves from the stems and store them in an airtight container. If you prefer a powdered form of stevia, you can use a food processor or blender to grind the dried leaves.
In addition to leaf harvesting, another method is to collect stevia seeds for propagation. Allow the stevia plant to flower and then carefully remove the seed heads from the plant. Place the seed heads in a paper bag and allow them to dry completely. Once dried, you can gently crush the seed heads in the bag to remove the seeds. Store the seeds in a cool, dark, and dry place for future planting.
Planting Stevia Seeds Indoors
To ensure a successful stevia harvest, it is recommended to begin the planting process indoors, approximately 8 to 10 weeks before the last frost. By starting indoors, you provide the seeds with a controlled environment that promotes germination and growth.
To start, fill a seed tray or small pots with a high-quality seed-starting mix. Moisten the mix thoroughly and then sow the stevia seeds on the surface. Gently press the seeds into the soil but avoid covering them completely, as stevia seeds require light for germination.
Once the seeds are in place, cover the tray or pots with a clear plastic wrap to create a greenhouse-like environment. This helps retain moisture and warmth, promoting faster germination. Place the tray or pots in a warm location, such as near a windowsill or under grow lights.
Within 14 to 21 days, you should start to see seedlings emerging. At this point, remove the plastic wrap and continue to provide adequate light and moisture. Avoid overwatering to prevent fungal diseases.
Replanting Stevia For Optimal Yield
For a successful stevia harvest, it is crucial to replant the herb annually. Although stevia is a perennial plant, its growth and yield tend to decrease after the first year. By replanting the herb each year, you can guarantee optimal yield and quality.
There are two options for replanting stevia: using seeds or cuttings. If you prefer seeds, follow the indoor planting process mentioned earlier. However, if you choose cuttings, simply take stem cuttings from an existing stevia plant. Ensure that the cuttings have at least three pairs of leaves and measure approximately 4 to 6 inches in length. Remove the lower leaves and apply a rooting hormone powder to the cut ends. Plant the cuttings in a well-draining potting mix and keep the soil consistently moist until roots develop. Once the cuttings have established roots, they can be transplanted outdoors.
By replanting stevia annually, you can maintain a healthy and productive plant, maximizing your harvest of sweet leaves.
Transplanting Stevia Seedlings
Transplanting stevia seedlings is a critical step towards successful growth and eventual harvest. Once the seedlings have reached a manageable size and the risk of frost has passed, it is time to transfer them to larger containers or outside in the garden.
If you choose to transplant the seedlings into containers, select pots with adequate drainage holes and fill them with a well-draining potting mix. The containers should be large enough to accommodate the growing stevia plant. Remove the seedlings from their original trays or pots, taking care not to damage the delicate roots. Gently loosen the roots before placing the seedlings in the new containers.
If you opt to transplant the seedlings directly into the garden, prepare a sunny location with well-draining soil. Ensure that the soil pH ranges between 5.0 to 8.0, although stevia prefers slightly acidic soil with a pH of 6.5 to 7.5. Space the seedlings approximately 18 inches apart in rows set 24 inches apart.
After transplanting, water the seedlings thoroughly and continue to keep the soil consistently moist. Be cautious not to overwater, as this can lead to root rot, especially if the stevia plant is grown in containers. Additionally, place the plants in an area that receives some afternoon shade to protect them from excessive heat and sunburn.
Ideal Growing Conditions For Stevia
To ensure a bountiful stevia harvest, providing the herb with optimal growing conditions is essential. Whether you are cultivating the herb indoors or outdoors, attention to certain factors can significantly impact the growth and yield of the plant.
- Stevia thrives in full sun but benefits from some afternoon shade, ensuring protection from scorching heat and reducing stress on the plant.
- Choosing a well-draining soil with a pH range of 6.5 to 7.5 is ideal for stevia growth.
- The soil should be rich in organic matter and adequately moist throughout the growing season.
- However, be cautious not to overwater, as excessive moisture can lead to root diseases and stunted growth.
For those with limited garden space, stevia can also be successfully grown indoors in containers. Ensure that the plant receives at least six to eight hours of direct sunlight each day. Placing the container near a south-facing window or using grow lights can help provide the necessary light requirements.

Pruning Stevia For Increased Leaf Production
To maximize leaf production and overall plant health, prune stevia when it reaches a height of approximately 8 inches. Pruning involves carefully trimming the top portion of the plant, encouraging the growth of lateral branches and more leaves for harvesting.
When pruning, use sharp scissors or pruning shears and make clean cuts just above a leaf node. This allows new branches to develop and stimulates the plant to produce fresh leaves. Regular pruning throughout the growing season helps prevent stevia from becoming leggy and encourages a bushy and compact growth habit.
By following these pruning practices, you can enjoy a continuous supply of sweet stevia leaves for all your natural sweetening needs.
