Vineyard-style training is also effective in training grapevines along walls and facades. Especially small espaliers can be established using this technique, as well as continuous espaliers or green "ribbons" of any height. By planting several vines, a designated greening area can be covered very quickly. The simplicity and efficiency of this training technique makes it preferable to the horizontal cordon.
Horizontal espalier ribbons require an espalier height of 0.7 - 1.2 metres; that is, the distance between the lowest and highest wire should be at least 70 cm. For aesthetic reasons, it is recommended to keep a minimal distance of 25 - 40 cm from house corners, windows, doors, and other wall openings (refer to Planning Tips). A vine with bilateral canes requires a width of about 1.5 m, and a unilateral cane a width of about 0.8 m. For a cane bent and tied into a circle ("circular cane," see below), the espalier width can be as narrow as 50 cm.
Small or narrow, ribbon-like trellises; for suitable wire rope systems, refer to Grapevines.
As illustrated in vineyard training: for the usual bilateral arched canes, 3 espalier wires are sufficient. For tall espaliers, the vertical main trunk is trained to the desired height; if growth is rather weak, this training period is extended by another year. For very small or narrow spaces, only one lateral cane is developed and tied as a circular cane (see below).
