The clear method is grazing within the Stevia patch, in regards to picking. Simply top off a leaf when you’re feeling like it and eat it. It is even better when joined with a mint leaf. With slightly more effort, you may use as you’d mint leaves, those fresh leaves to create a tea using a tea ball or strainer.
Harvest time actually rolls around when plants are fully developed. You will get the highest combination of glycoside content and leaf yield before plants begin flowering. Proceed and pick, when you see the first flower buds forming.
If you’re growing Stevia as a perennial, you may need to depart about six inches of the plant for re-development. Otherwise, cut tie using a rubber band into little bundles and entire stems right away. Make use of a bent paper clip to hold these bundles inverted in a well-ventilated location from direct sun. Elongate some strings around the ceiling to hang them from in case you want more hanging space.
The leaves will probably be fine and crispy in a day or two, but still brilliant green. Strip the leaves off by hand and lose the stems, as they don’t as bad. Shop dry leaves in a clean glass container with an excellent tight lid on top. Place in a cupboard from the sun. They will keep for years that way. You will get some outside to process farther as needed.
Another drying method would be to strip leaves from stems while still fresh and spread out on the display from the sun or in a dehydrator on low heat (under 110 degrees F.) up until crunchy. Leaves are prepared to processor store away for later.
