Full greening means serious, full-faced "cultivated green up" of a facade or other wall areas and surfaces. It is regarded as supremely ecological. This green up concept often thrives without growing structures. However, whole trellis walls can be designed of wire-cable or wood depending on the plant (see below). Also mixed greens planting is possible. If you think about a bigger surface greening, this page can serve as a base for decision making.
With a full surface green up in densely populated cities one can actually improve the summer microclimate. Even birds and insects get an additional habitat - real animal protection! Your costs only begin when the plants reach the roof and need trimming at regular intervals. Depending on the plant there is also significant autumn foliage quantities to be disposed of! There are also possible structural damages and tenant dissatisfaction because of spiders, critters, and darkened, overgrown windows ... Another creative tip: At least in some places, the facade should remain non-greened to create an enchanting sight.
Self clinging climbers (plants that climb up themselves without any wire, cable or wooden trellis) need almost no trellises - so they can be used very inexpensively to create surface greening. This is especially true for Ivy, this "year-round" retains its leaves. Boston Ivy and Virginia Creeper walls are usually fast-growing and have bright red autumn leaves. However, their appearence in winter is not always sightly.
Most climbing plants need Trellises to completely cover a wall. The classic full-planting was done earlier with trellis vine, because then planting was seen in terms of yield. But vines need care and for basic start up knowledge expertise is required, which can be found on this website. Also with climbing roses, larger surface greening can be created, and if necessary, Clematis and annuals can also be introduced
