robinia-pro PATH EDGING made of wood, flexible

Robinia wood is ideally suited for wooden path borders in the garden. No other wood lasts as long in the ground, nor do any of the offered tropical woods, see the topic page “Robinia wood”. Likewise, the durability of pressure-treated woods does not compare to that of Robinia wood (additionally: The preservative eventually becomes non-biodegradable poison in the soil). A path border made of Robinia wood is a lasting investment that also impresses with its environmental friendliness and aesthetics.

Robinia wood for path borders is the most durable, provided you like wood. No other wood lasts as long – by far. A lifespan of 20 years or more is realistic, even in heavy, moisture-retaining soil. Even wood treated with fungicide in a pressure process cannot compete.

The wooden path border consists of slender octagonal posts with a thickness of 3 cm, “strung” on wire of 2.5 mm (one wire on top, one wire on the bottom). Many heights can be produced. For example, 5 cm high, 10 cm high, 15 cm high, 20 cm high, 25 cm high, 30 cm high, 35 cm high, 40 cm high.

The posts have a stylish “dome” – see close-up in the gallery. The posts are deeply impregnated with pure linseed oil, which further increases durability.

In the two end posts of a path border module, there are holes in both longitudinal and transverse directions for Robinia wood dowels (included), which allow the path border modules to be connected, either lengthwise or at a right angle – see photo in the gallery.

The lengths of the modules are staggered in 15 cm increments. By appropriately selecting the module lengths, various total lengths of the path border can be created. If it doesn't fit and you need it exactly, you can reduce the length of a module by shortening the two wires and removing posts (best done simply with a hacksaw between the posts).

The modules can be bent with light force, up to a radius of 33 cm. In very moist conditions, it is advisable not to fall below a bending radius of 40 cm, as the wood swells significantly due to moisture.

Therefore, you can create any length and shape of the wooden path border.

At the two end posts of a module, the wire is firmly wedged. In between, the posts are freely movable. There is some “space” between the posts – room for the posts to swell due to soil moisture. The posts will eventually stand closely together.

How high to choose the path border? That depends on how high the path border should stand. For stability, the path border must be anchored in the ground at least as deep as it stands high. The height of the path border to be chosen is therefore at least twice the desired height after installation.

Installation: To install the wooden path border in the ground, a small trench needs to be dug; the depth is determined according to the above. Once you have finished the trench, set up the wooden path border in the trench as it should run; the modules are connected using the Robinia wood dowels. With some soil, secure it in height and laterally. Then carefully fill the trench starting from the lower side, pressing the soil down repeatedly, and finally compact the soil once more. Finally, fill in the other side, avoiding excessive pressure (as the anchoring in the ground only reaches its full strength over time).

The advantage of the wooden path border is that the modules can be shortened by removing posts, which carries a certain (small) risk that posts may slip out on their own. If a greater force acts during transport, it may not withstand the wedging of the wires in the outer posts. We are not immune to such occurrences on the way to you. It can also happen at your place. However, this is not really a problem. You simply re-thread any slipped-out posts. The posts are fixed in place by the soil. If necessary, you can also restore the wedging by driving a small pin (nail) of 2 to 3 mm thickness into the holes with the wire; that’s how we do it too – see the outer posts that are firmly seated.
