Yes… and no… Although we do harvest plants that grow naturally, without seeding or planting or fertilizing, we do manage the plants. In the agroforestry system we manage, we first coppice old stands of rockrose to a height that promotes a leaf growth, then we wait 2-3 years to go back to the same plant to coppice again, while promoting the natural regeneration too. We know which alleys of the agroforestry system have been harvested, so we can make our harvest plant every year.
