A netting installation, for use in tree fruit production, which comprises a framework comprising a plurality of uprights which are mutually spaced to form an array of the uprights. Each upright is installed into the ground using a helical ground anchor, and has a combination of upper and lower slidable parts to removably fit an upper part onto a lower part which is installed in the ground. Cables are attached to the upper ends of the uprights to form a cable network at least 3 meters above the ground. A plurality of nets are mounted on the cable network to form an array of nets. A releasable net tethering system connects the nets to the cables using connectors fitted between the peripheral edge of a respective net and a cable, wherein each connector has a preset maximum threshold of tensile strength.
