Tips for Attaching Trellises

Which holders are suitable for which trellis and how many fixings are necessary? Which wall distance makes sense? These questions are discussed here. It should be possible to fix a trellis on all wall types! This page is still under construction.

How to fasten

In the past, trellis spars were placed in cemented wall hooks and probably fixed with bast or the like. So trellises - as here - could be quickly removed for repairs. Even with modern anchors, a trellis field can be quickly detached, e.g., when the façade needs renovating. Almost all of FassadenGrün's holders also provide a seal.

The transverse bars are usually anchored to the wall, the vertical slats are then screwed onto these bars or "cross bars". Very large trellises, many meters wide, are divided into individual panels or trellis grids, which can then be removed separately. We recommend to do an extra drawing for the drilling points. More info under "Step by Step".

How many Holders?

The number of wall fasteners depends on the trellis width. For details on the density and distance of the attachment points, refer to the product sheets of the trellis anchors. With weak brackets such as AS 0855, the stability of the trellis can be increased if the number of attachment points is increased.

Wall Gap and Wall Clearance

A trellis should also provide enough distance from the wall. At first, the gap between the wall and the back of the trellis cross bar is measured. For the individual trellis holders it is 1 - 5 cm. The actual wall distance of the plants is calculated from this wall gap and the sum of the wood cross sections. This is, with a lath thickness of 27/27, another 5 - 6 cm. For this, usually 1 - 5 cm wall gap and accordingly 6 - 12 cm wall distance are sufficient, more can be found on the individual climbing plant pages.

Small Wall Distance

A small wall distance of about 5 - 6 cm (as with the trellis holder "Mini") is a low-cost alternative and works for plants whose shoots have no tendency to loll and do not grow behind the trellis. Otherwise, the annual removal of such shoots becomes very annoying. The actual wall gap is then only about 1 - 2 cm.

Medium Wall Distance

An average wall distance of about 10 cm is useful for many creepers and climbing plants, whose annual shoots like to be put behind the trellis. Thus, the maintenance work is reduced because the attachment is omitted. Medium wall distance as with the trellis holder Classic: So shoots of annual or light plants (here hops) can even loop around the slats. The actual wall gap is then about 5 cm.

More wall distance

A very high wall distance of about 15 cm reduces the mildew risk for susceptible plants such as climbing roses and wine. In general, however, the topic should not be overestimated here, especially for large, older plants. The shoots become entangled with each other and create their own optimal wall spacing by freely growing in the space in front of the wall. The trellis then only anchors and ventilates the branch structure. Particularly high wall clearances can be achieved with AS 12XX0. The actual wall gap is then still only 7 - 9 cm.

Problem Case Insulation

For low-loaded trellises on walls with insulation up to 6 (12) cm, the anchor bolt for ETICS is often sufficient. The AS 12XX8 or AS 12XX6 are suitable for massive, more heavily loaded trellises, for larger insulation thickness of up to 12 cm and also for higher wall clearances.

Attaching the plant

Young and old plants are attached to trellis with binding material.

Prevent Damage

Regardless of the distance to the wall, perennial shoots that from the plant structure must never grow behind the trellis or wrap around it. Otherwise the plants increase in thickness can, but most likely will damage the trellis or growth structure as with this Wisteria to the right.
