This disclosure involves advancements in grafting, trellis design, and an implement to raise and lower cold-sensitive vines between a raised growing position and a lowered position where the vine is buried in a trench and covered to protect it from the cold. The implement relieves the operator from the otherwise laborious task of protecting the cold sensitive vines. The apparatus allows the cold-sensitive vine to be buried into a trench without removing the vine from the fruiting wire. The implement directs the fruiting wire with a vine cordon attached thereto into a trench to protect the cordon from cold temperatures. The apparatus causes the vine trunk to bend to accommodate the position of the vine cordon.

An adjustable fence-top trellis support bracket assembly forms the basis of a system for creating adjustable trellises on two sides of a fence or wall, and includes a) an elongated support bracket member, b) curved-loop ends on the elongated bar member and the adjoining bracket portion wherein one is attached proximal one end and the other proximal an opposite end of an elongated bar member; c) a movable L-shaped leg generally perpendicular to an elongated bar member of the elongated support bracket portion, wherein the movable leg is engagable with the elongated support bracket member; and d) a means for adjusting and then securing the movable L-shaped leg against the elongated bar portion of the support bracket member.

A trellis is described herein, including a series of upright posts, cross beams supported by the posts in an elevated state, at least one line holder fitted to each beam, each holder having one or more downwardly facing retaining slot or slots, and vine lines connected to the holders such that they are located in and pass through the retaining slots so that the lines run laterally in rows and can be non-destructively removed from the slots by exerting downward pressure on the lines.

An agricultural trellis system is provided and generally includes a notch configured to receive a trellis wire therein and selectively release the trellis wire upward during mechanical pruning. The notch can be positioned on an above-ground portion of a vertical line post or a cross arm. The notch can include a tab extending upward from the bottom of the notch, and a first edge and a second edge each formed on the body. The first edge can be a flat edge and can be positioned laterally outwardly from at least a portion of the second edge, which can be a curved edge. The notch can include a retention protrusion extending laterally into the notch toward the second edge to a position where a lateral distance between the retention protrusion and the first edge in a direction normal to the central plane is less than a diameter of the trellis wire.

A support device, or hook, for removably securing movable wires on a row of plants, such as for example a vineyard or an orchard, on a support pole. In particular, the support device is made up of an elastically deformable filiform body, shaped in such a manner as to have at least engagement elements adapted to elastically cooperate with an opening provided on said support pole to removably secure the support device on the support pole, and support elements, adapted to elastically cooperate with the external surface of the support pole to removably receive said wire, wherein said engagement elements and the support elements are formed by portions of the filiform body lying on planes essentially orthogonal to each other.
