Twiners, Vines or Lianas love ropes and rods, around which their main shoot can twine like a spiral. For annual climbers and the more fragile twiners such supports are acceptable. However, the main stems of perennial and vigorous twiners must be unwound and tied to the external side of the trellis, as is described under Wisteria. Otherwise, massive trellises with extreme distance from the wall (15cm+) are required, which will cost several times more than the ordinary growth supports.
First, there are annual lianas that die completely after the fall such as Morning Glories, Spanish Flag, and scarlet runners. A well-known climbing plant, which dies in autumn, but sprouts anew next year is the hop. Perennial, i.e., woody species are Dutchman's Pipe, Akebia, wintergreen and "normal" honeysuckles as well as kiwis. The so called "Vigorous climbers" such as Wisteria, Silver Fleece Vine and Bittersweet need special attention during the early development phase! Twining plants are often bare at the lower areas, but this is often counterbalanced by a towering overhanging growth.
Twining climbing plants love ropes and rods around which their main shoots can spiral helically. For many twining plants, for example, annual bloomers, this is acceptable. In the case of vigorous twiners, however, it is essential that the main shoots be unwound and attached on the outside of the trellis as described for wisteria. This will prevent damage. Otherwise, martial trellises with wall spacings of over 15 cm are required, which are much more expensive. Each vine page has an overview below, in which the more or less suitable rope systems are marked in colour.
Above all, vertical ropes are very well accepted - even if several are next to each other, onto which several shoots of ONE plant or possibly even several plants are led. Short, minor cross sections can positively promote the interweaving of the individual green strands. For annual plants, easy and light cable systems are often sufficient. All perennial twining plants need at least medium, better heavy or massive wire rope systems, not least because of the heights that are achieved. In the initial phase, "climbing rungs", for example in the form of attached clamping rings, prevent slipping. However, the binding with binding material fulfils the same purpose.
Only "conditionally suitable" for twining lianas are cable systems which contain considerable horizontal ropes. The creepers despise these ropes, individual shoots must first be placed horizontally and tied there. This results in an increased maintenance effort! In the private garden, however, this is usually not a problem, because once a horizontal branching has been set up, these areas will be greened reliably.
Even arrangements in which the ropes are "close meshed", sometimes are only "conditionally suitable", the explanation follows below. And finally - for less vigorous plants - rope systems can be too high.
"Not suitable" are, for example, arrangements with only short cable lengths. They do not do justice to the growth behaviour, except perhaps in potted plants. Even tightly packed, "dense" cable systems such as 5050 are often not necessary because they are too expensive. Some lianas, especially in the above-mentioned vigorous twiners, several tightly guided, parallel ropes are already a hindrance, because the plants then strongly interlock and the pruning takes longer. These plants are better to lead on separate, individual ropes, which should be at least 1 - 1.5 m apart.
