Coffee Scout: Gustavo was our guide at Daterra. Here he is digging into the ground cover a bit to show the layer of leafy mulch and weeds allowed to remain between rows of coffee shrubs. They mow the weeds when they get too high, but it offers a good layer of protection and more organic material for the deficient soil. They keep the weeds away from the trees so they don't compete with the coffee. For that they use RoundUp, unfortunately.
