Tips for Attaching Trellises

This section addresses which trellis fittings are compatible with what trellises, how many fittings are suggested per trellis and the recommended distances between trellis and wall. It should be possible to fix a trellis on to all wall types! This page is still under construction.

How to fasten

Originally, trellises we hung on pre-cemented wall hooks and secured with bast or similar, fibrous material. This was so they could be easily removed should the wall need any repairs or maintenance but even with modern anchors, a trellis can be quickly detached if, for example, the façade needs renovating. Almost all of FassadenGrün's holders also provide a seal.

Usually, it is the lateral slats which are anchored to the wall and, once secure, the vertical slats are then positioned and screwed over them. Very large trellises, multiple meters wide, are divided into individual panels or trellis grids, which can then be removed separately. We recommend that you measure and demarcate the points at which you want to drill rather than taking a spontaneous approach. 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 between attachment points, refer to the product sheets of your specific trellis anchors. With weak brackets such as AS 0855, the stability of the trellis can be better insured if the number of attachment points is increased.

Wall Gap and Wall Clearance

When fitting a trellis you should also be aware of providing sufficient distance between it and the wall so that your plants do not feel suffocated. First, the gap between the wall and the back of the trellis cross bar is measured. For the individual trellis holders it is 1-5cm. 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 5-6cm. For this, usually 1-5cm wall gap and accordingly 6-12cm wall distance are sufficient, more can be found on the individual climbing plant pages.

Small Wall Gap

A small wall gap of about 5-6cm (as with the Trellis Holder "Mini") is a low-cost option and works for plants whose shoots do not have the tendency to meander and curl behind the trellis, otherwise the annual removal of such shoots becomes very annoying. The actual wall gap is then only about 1-2cm.

Medium Wall Distance

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

Greater Wall Gaps

A very high wall distance of about 15 cm reduces the risk of mildew for susceptible plants such as climbing roses and grape vines. In general, however, the topic should not be overestimated here, especially for large, older plants. The shoots can easily become entangled with each other and create their own optimal wall spacing by freely growing in the space provided, between the wall and trellis, in which case the trellis only anchors and ventilates the branch structure. Particularly large wall gaps can be provided with the AS 12XX0 but even then, the space created will not exceed 7-9cm.

Problematic Insulation

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

Attaching the plant

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

Preventing Damage

Regardless of the distance from the wall, perennial shoots that form the plant structure, must never grow behind or wrap around the trellis, otherwise the plants growth, and more specifically girth, can and very often will damage the trellis or growth structure, as with this Wisteria to the right.
