Ever wonder how Pecans are harvested? This Video will show you how! Here in Green Valley, we use the latest and greatest in farming equipment technology to ensure the freshness and taste of our pecans. Unlike most fresh produce, which is harvested during the summer months, pecans and other nuts wait until fall. For pecans, harvesting waits until the first hard freeze of winter. This first freeze kills off the green protective shuck around the nut itself causing it to open and expose the pecans inside. It is at this time when harvesting will begin.
