Here we will address those slender, vertical columns-- components of a building that have a 'ballast' at the top. These are: columns, pillars, balcony supports, props, building supports, and posts of a pergola, and we'll show you how they are greened into 'plant climbing pillars' or 'plant climbing supports.' Wire ropes are ideal as a climbing aid for such vertically-oriented building components because they can be removed. Thus, the climbing plant can shine and one gets the impression that the arrangement was created naturally... that is, by chance. (We've dedicated an extra section on our website for the greening of free-standing masts and posts.)
This means that only the pillar or support is greened and not the area around it. The climbing plants should be correspondingly slow growers or easily-tamed continuous bloomers. Mandevilla, clematis, rose and grapevine are possible... the latter as vertical cordon or small espalier/trellis.
Such columns usually 'dislike' being drilled into; where possible, subtle individual attachment points in accordance with cable system 1010 or vertical ropes like 1020 and 1030, are sufficient. Depending on the desired effect (one-sided or circumferential greening), set 1 -5 parallel ropes per column. In the case of angular supports (rectangular/with corners) and with a larger width, more than one rope can be tensioned per area-- cable system 4020 is appropriate. For questions about fastening/attachment, see below.
This means that the wall area above a support, a pergola, or a balcony is greened, or that the greening will take place primarily in the upper area and the support only then serves to guide the shoot structure of the climbing plant upwards. A vertical wire rope 1020 or 1030 as a climbing aid usually suffices for fastening. Sometimes an easy construction style suffices. Combination systems like 9010 and 9020 can be used here. If there is a wall offset/misalignment, vertical and horizontal ropes are laid separately.
Similar examples can be found under "balcony greening."
Greening can also be taken to great heights and "distributed" to supports via wire-cables... so, several balconies or whole arbours/arcades can be greened. The attachment along the vertical supports can be relieved and is less stressed if the climbing plants are also fastened laterally to balcony parapets, etc..
What should the distance be between ropes and a climbing support? In the past this pesky question was often solved pragmatically: there was almost no distance! The wires were laid very close to the columns. The Easy Kits from FassadenGrün, which are often sufficient for columns, etc.. correspond to this older method. However, Medium or Heavy Kits are needed from time to time. Even a massive construction style is possible for representative or design reasons.
