2-bar espaliers in the classical shape consist of 2 strong crossbars and vertical laths protruding on top and at the bottom, ocasionally a bit more on top. They look like a garden fence tacked to the wall, and are suitable for laths made of conifer wood, which do not warp. In the cases of larch, oak and robinia wood, meaning hardwoods, warp and a respective rustic look must be taken into account. Now and then, this is wanted, mostly though, 3-bar espaliers are favored then. 2-bar espaliers can be utilised alone, in groups, or as espalier bands. For further details, such as cross sections, spacing between laths, fastenings, and so on, please click on the respective sites.
It is important for the planning to include spacing on all sides, building the espalier to some extent a little smaller and “indentured”, because this looks more delicate and the respective plant usually spreads beyond the edging of the espalier. The quantity of the wall fastenings depends on the espalier’s width, mostly though, 4 anchors, 2 per espalier bar. Please consider the maximum spacings recommended for the individual anchors. The anchors are not set all the way outwards, but circa 20-40 cm indentured. At least two vertical espalier laths are attached to them.
Long espalier walls for fruits and wine often have been found on large buildings and their backsides, on long walls and especially in kitchen gardens of lordly manors. They have a tradition in garden art as well, and were for instance planted with roses. On a separate site, narrow espalier bands or belts called “belt espaliers” will be discussed.
What can be done if there are (smaller) window openings in a planned espalier system? While in the past, such openings simply were “overlaid” with laths and greened, they are omitted today. That consequently demands deviation in the array of the bars. How can be proceeded? On the photos you find suggestions thereto. The easiest way of course, is to intermit the espalier completely in the area of recess and continue after that, meaning two espaliers both on the left and on the right side of the wall opening are to be arranged – see below.
Several espaliers often are arranged between windows, doors, etc.., if their size does not allow a continuous espalier system. Sometimes, even creative aspects determine the mounting of several, single espaliers instead of one large espalier system. Often times, the lines of the window row are “taken up“ – mostly in the shape of arranging the upper lath knobs on one line with the upper window borders. It is possible though, to set the crossbars in the flight of the upper or lower window border as well.
