How to tell it is ready

Leaves are ready to pick once the plant is established and has grown bushy, typically about 40 to 60 days after transplanting for light picking. The sweetness peaks as the plant matures in late summer and reaches its highest concentration right before flower buds open, which is the ideal window for a main harvest. If you taste a leaf and it is pleasantly sweet with only a faint aftertaste, it is ready.

How to harvest

For a light harvest, pinch or snip individual leaves and the top few inches of stems, which also encourages bushier growth. For a full harvest, cut whole stems near the base or shear the plant back by about half with clean scissors or pruners, then strip the leaves from the stems. Handle the leaves gently to avoid bruising, which can affect flavor.

Timing

Harvest in the cool of the morning after the dew has dried, when the leaves are most flavorful and the plant is not heat-stressed. You can take multiple light pickings through the growing season and one or two larger cuttings, allowing four to six weeks of regrowth between hard shearings. The main harvest generally falls in late summer to early fall, with plants reaching full harvest maturity roughly 90 to 110 days from transplant.

After the harvest

After cutting, rinse the leaves gently only if needed and shake or pat them dry, since excess moisture slows drying and can cause mold. Move harvested stems out of direct sun promptly and begin drying right away by hanging bundles in a warm, airy spot or spreading leaves in a dehydrator. Stevia does not need curing; the goal is simply to dry the leaves quickly and thoroughly.

Tips

Time your biggest harvest just before the plant flowers to capture the sweetest leaves, and pinch off flower buds during the season if you want to prolong leaf quality. Always leave several inches of growth and some lower leaves when shearing so the plant can regrow. In frost-prone areas, take a final generous harvest before the first fall frost, since cold will kill the plant.
