The Stevia plant is a leafy, tender herb perennial with leaves naturally so sweet, that it is marketed as a sugar substitute (more than 100 times sweeter than sugar). This close relative to the chrysanthemum prefers a subtropical climate above 20 degrees Celsius, which makes it a wonderful species to grow in South Africa. It can last several years in favourable conditions.
Common problems with Stevia
The main pests that seem to affect Stevia are aphids, whiteflies, cutworms, moles, thrips, slugs and snails. Spray the leaves with a pungent organic spray that contains garlic, chili and rosemary to deter and control pests. Place a thick layer of crushed egg shells around your plant to deter slugs and snails.
