Wire frameworks are a classic, million-times tried-and-true system for fruit growing, and can also be installed at home in the garden. Trellising with stainless steel cables is particularly practical for grapevines, raspberries, blackberries, or other espalier fruit trees. Here you can see the different possibilities, from the simplest wire trellising to the most complex pergolas. Under wire rope system 0050, you will find two of our ready-made kits.
Wire frames in the vineyard are often more than 50 metres long. The trellises, subjected to the force of the wind, loosen and sag. This constitutes an aesthetic defect but not a functional one. In commercial orchards, the wires then usually remain slack or are retensioned every few years. In the house garden, short wire frames usually only have 2 -3 posts/supports; for this FassadenGrün offers stainless steel cable system 0050.
Wire frames in vineyards often have 2 wires- so called "double wires" on each level. In addition, there are sophisticated spacers which keep the wires apart. All this makes fastening the vines to the wire frame easier: the vine shoots can be inserted more quickly between the wires, and tying is no longer necessary. In the house garden, however, double wires are superfluous for vines.
The vine can be trellised just like fruit trees. In the home garden, wire frames are ideal for espalier fruit (for grapes, raspberries and blackberries)... Instead of stainless steel cables, simple wire of four or more horizontal lines (usually with double wire on each of the tiers). The sloped 'guy' ropes (tensioning ropes) are suitable for additional greening, e.g. with annual climbing plants.
Here rot-resistant pointed (Robinia) stakes/posts are driven or, more simply-- hammered with a hand hammer (stake driver)-- into the ground (life span approx. 10-25 yrs), the wires or ropes hanging slack because high loads are created in tensioned wires which want to pull the lateral stakes inwards. The stakes should therefore be set at an angle to the outside right from the start, or better, braced using one of the three options below.
Here is an example of the simplest wire frame design-- a double espalier/trellis for raspberries-- without any reinforcement or stiffening of the posts, and therefore with relatively slack wires. The three variants described below are available for additional bracing:
- Tensioning (standard solution)
- Stakes/support posts
- Cross (transverse) beam
In the case of Robinia wood, the slanted support stakes/posts are cut to mitre as accurately as possible and screwed to the end posts. Here-- in a vineyard -- galvanised lock bolts are used instead of stainless steel. The aggressive Robinia wood, however, already dissolves the zinc coating, as can be seen from the discoloration.
Usually the final/end stakes are anchored in the ground at an angle towards the back. In vineyards, heavy stones are also buried in the ground with a wire attached, thus creating and strengthening the tension.
The anchors are not quite set on top but at approx. 2/3 the height of the stake/post to prevent the post from bending in the direction of the the tension wires or stainless steel cables.
FassadenGrün recommends this ground/earth anchor for an easy and optimal "guying" --tensioning/anchoring. It is driven into the ground like a screw and can support loads of several hundred kilograms.
The system 0050 is also useful when, for example, a neighbor's garage wall may not be "bored (drilled) into." Here, dark glazed wooden posts were placed in metal ground spikes (impact sleeves) and fitted with galvanised (zinc plated) cover caps (available in hardware stores). The tensioning of one side (in the photo above right) was done with a horizontal stainless steel cable and a level into a boundary wall. Another example can be seen below in a photo.
As an alternative to the tensioning described above, support poles/stakes can also be used as a 2nd variation-- e.g from Robinia wood - and then dug in and set on a stable pressure plate. This can be a stone or a brick. the ground below the pressure plate must be compacted somewhat pressure-tight. When installing the poles, they should lean outwards slightly, to counteract the subsequent settling and tendency to shift inwards.
Here the ropes of several fans intersect each other, creating a dense vine braid. In the middle at the bottom, a ground anchor is screwed in. Eyebolts WH 06060 or inexpensive staples nails KN 04055 are screwed into the frame of the wood. A cable can also be carried by multiple eyelets (3 or 4), so that ultimately fewer cable clamps are required.
Climbing aid made of soft wire-cable over-crossing or threading. Thin stainless steel wires are fundamentally "softer," more flexible and thus more easily guided into angled shapes (so forms with edges), especially for short distances. In such cases, the comparatively harder wire makes tensioning more difficult --kinking and threading eye bolts, as well as threading wires...
FassadenGrün recommends and sells this wire tension adjuster which can be retrofitted onto taut or slack wires (to some extent also onto 3 mm (0.11 inch) wire without cutting the wire, and can be finely tensioned at any time with a spanner/wrench.
