Mulching stevia plants is a good idea in order to retain moisture and also because the feeding roots of the stevia plant grow very shallow.
Cool autumn temperatures and shorter days intensify the sweetness of the plants so harvest as late as possible while avoiding exposure to frost. Covering the plants should give you the benefit of another few weeks’ growth and more sweetness.1
These estimates for how long Stevia takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
