Trellis
A framework fixed in glass houses near the roof, on which to train plants and trees, such as Vines, Peaches and Nectarines, Cucumbers, and Melons, none of which could receive proper attention unless so treated. A Trellis may also be formed to fix into a large pot for the accommodation of an individual plant, as, for example, a Stephanotis or Bougainvillea grown for exhibition. Galvanised wire of different sizes is generally used, according to the different purposes for which it is intended. In Vineries and Peach-houses, the Trellis should be fixed, not less than 1ft. from the glass, as it is always required; in Cucumber and Melon-houses, it may be in pieces, so as to be removed when the house is used for growing other plants which do not require a Trellis. The wires for training Vines upon should be fixed horizontally, 9in. apart; and for Peaches and Nectarines 6in. is preferable. When a Trellis is made in movable sections, the wires are usually crossed, to form a diamond-shaped pattern, and this allows of plants being tied and trained in any direction. Pyramid and balloon-shaped Trellises are those usually selected for specimen pot-plants.
