Although stevia can be started from seeds, but it is best to grow from rooted cuttings. Buy a small stevia plant from your local garden centre, look in the herbs section.


Stevia grows well in a rich loamy and well draining soil or even in general purpose garden soil. Stevia will not grow in salty soils.


Stevia plant has root system near the surface, so it may dry out in summer and
needs frequent shallow watering. But note that excessive moisture or over-watering can adversely affect the growth. The plant will be benefited by putting a layer of compost or mulch on the plant, specifically for pots.

Generally, if the stem tips of your stevia begin drooping, it is time to water.


  1. In the first year of my stevia plant, I did not prune the leaves, so it grew into a tall plant with 7- 8 branches. It produced tiny white flowers in late summer.
  2. When the plant is about 8-10 inch tall, trim the tips of the branches to induce branching to maximize leaf production.


The stevia plant has low nutrient requirements. I usually feed with a balanced liquid fertilizer every 3rd week.


The stevia plant is relatively free from any pests attack and diseases. The stevia plant has insect-repelling properties. Their natural sweetness is a natural deterrence to aphids and grasshoppers that find it not to their taste.

  3. The cool autumn temperatures and shorter days increases the sweetness of the plant.
  4. Generally you can start harvesting when plants are 40-60 cm in height.
  5. Once you harvest all the leaves, put them under full sun for 12 hours to dry.
  6. You can store dried stevia leaves in an airtight container in a cool dark place.
  7. To release the stevia’s sweetening power, crush the leaves either by hand or in a coffee grinder.
