When are tension cables (mounted steel wire ropes) as plant supports useful?Which wire rope arrangement is suitable when? Which construction style (light, medium, heavy...) is recommended when? Which is better: a pre-assembled kit or my own assembly (from components)? How important is the distance from the wall? Is any wall surface suitable?
Here you can find answers to these questions, as well as other tips on choosing a suitable climbing aid for your plants in rope tensioning technology. Stainless steel is highly recommended; otherwise, expect damage and rust with a lesser quality metal.
Wire ropes function in a variety of ways, depending on a climbing plant's growth type. Initially, they serve as a ladder for young shoots to grab hold of and climb. 'Twining plants twine and twist their shoots directly around the cable, but a permanent entwining is only suitable with light or moderately-twining climbing plants. Vigorous twining plants need to be guided parallel to the wire rope strands, as described for wisteria.
Old or shrubby plants are fixed to the cables by tying. Sometimes cables are used as a template/mould to guide the plants into particular shapes (the plant is strictly trained along those lines). Cables are also used as 'fall-protection' for self climbing plants, such as ivy. (See the photo gallery below).
Where possible, the plant should always be guided in front of the support (trellis) system. This allows proper ventilation, without which, the plant is quite susceptible to mould. To this purpose, the trunk frame and branch work of climbing plants are built up on the outside of the ropes or trellis slats. The 'old wood' (older vines and branches) are tied and bound (see link for binding material) to the supporting wire ropes. The respective vine should not be allowed to grow around or behind a supporting wire rope.
Only when the purpose of the cable system is as a 'fall protection' (so the plant does not fall off the wall) will the shoots then need to interweave with the cables and may grow behind them. Young green shoots that do not become part of the main branch framework can be tucked behind ropes. These shoots are then removed during the pruning periods.
A climbing aid (wire rope support system) should help the plants grow upward and allow them to ventilate by leaving sufficient space between the leaf mass and the facade. People have a tendency to go with overly excessive cable tension techniques or overestimate the number of cables needed.
What is important in the initial development phase of the plants later plays only a minor role. As plants grow and age, they catch, entwine, and anchor themselves with their own shoots; the young shoots will no longer depend on the cables to climb. They will naturally move towards the light and therefore towards the outside, which will automatically create an 'empty' space between the vegetation and the facade. The purpose of the trellising system is above all to support the trunk of the plant. Our medium trellis system ('medium kit')- with a 5 cm distance between the wall and the plant- is sufficient in most cases. For more information, see the sections on wire rope systems provided under ohur individual climbing plants.
If you want to trellis branches of the same plant on two side of the same building (so, guiding plants around building corners), two separate climbing aids have to be placed on each wall. The gap is bridged with the vines' own shoots. Stouter/thicker shoots can also be led around the corner. The same goes for horizontal projections, like ledges.
Some plants, like wisteria, are often cultivated as a single strand (guided on one cable) because the pruning and care is easier. For most plants, however, planar arrangements make more sense. A design question arises: shall the tension ropes be arranged individually as parallel lines, or is a grid-like lattice structure better? For architectural reasons, it is sometimes necessary to arrange individual cable strands parallel to one another, without cross-connections (transverse/intersecting lines). This applies equally to horizontal and vertical lines. Such climbing aids appear sleeker/more stream-lined, more pleasing, and often harmonise better with the design language of the building. For the plants themselves, however, grid arrangements offer more 'grip' and are therefore often preferable. Under wire rope systems, you can review both options.
Ideally, you already know what you would like to see growing on your facade... if so, find your respective chosen plant in our climbing plants section. There, in the chart at the bottom of each plant profile, you can find the most suitable shapes for a cable trellis. Choose an arrangement ('wire rope system') fitting to your situation. The next step is to choose a construction style (easy, medium, heavy, massive...).
If, for whatever reason, you have not decided on a specific plant yet but wish to quickly assemble a trellis system, we have developed universal systems for you that are compatible with almost every plant (with the exception of vigorous twiners like wisteria): 1030, 4030, 5030, 5040, 7020, 7050, or 8010.
A word in advance: for climbing plant support systems, there is no real alternative to stainless steel. Other materials usually cause damage of some sort. Wire rope technology from FassadenGrün is exclusively made of high grade stainless steel. We offer five different construction styles: easy, light, medium, heavy, and massive. Basically, all of our pre-assembled wire rope systems ('kits') are available in these five styles, classified according to difference in design, wall distance, load-bearing capacity, and price. Again, refer to the charts at the bottom of each climbing plant profile, to see which construction style (easy, light, medium, heavy, massive...) fits to which climbing plant.
Many applications can be satisfied by FassadenGrün with the purchase of our ready-made kits, as opposed to buying a collection of individual parts. Such pre-assembled trellis sets are suitable for all wall types with the exception of: insulated walls (ETICS), cladding, and thin-walled concrete elements. Alternatives can be found for these cases. Very big greening fields can and should be grouped into several smaller fields, next to each other. This makes the use of standard wire rope systems easier.
When necessary, you can also modify and enlarge basic shapes by ordering individual parts in addition to kits. We can advise you on how to enlarge a facade greening, or let us know when you place an order what your needs are. You can also refer to our section on Climbing Plants-- the charts at the bottom of each plant profile. Here you may find arrangements you prefer for your special case, depending on your preference for more dense or spartan, horizontal, or vertical forms. With this knowledge, you can put your own original kit together from components in our "Individual Parts" section. The mounts you choose should have approximately the same wall distances as a comparable wire rope system would have.
