Please make sure the seedlings are well-watered but not waterlogged before transplanting them into the soil. Choose a sunny place with well-draining soil for your Stevia seedlings.

Dig a hole compared to the root ball of the plant and place the seedling in, ensuring that it sits at the same level. Cover the plant roots with soil and pat down gently to secure the plant in place. Water thoroughly after Stevia planting to help settle the soil around the roots and provide much-needed hydration for your new Stevia plant.

Regularly check on your seedlings to ensure they are thriving in their new environment. To start, select healthy stem cuttings with at least 3-4 nodes. Using sterilized pruners, make clean cuts at a 45-degree angle. Remove the lower cutting leaves, leaving only a few on top to prevent moisture loss. Dip the cutting in rooting hormone powder for better root development.

Plant the cutting in well-draining soil or a mix of perlite and peat moss. Keep the soil moist but not waterlogged, and place the pot in indirect sunlight to encourage root growth. Within a few weeks, you must start seeing new growth, indicating successful rooting. Once roots have developed, transplant your Stevia plant into a big container or directly into a garden bed, where it can thrive and produce its natural sweetness for years to come!

Watering and Irrigation Best Practices

Proper moisture levels are essential for the growth and development of healthy plants. Consistency is key when it comes to watering your Stevia crop.
