Roses can get very old. So that one day they don't stand there without a foothold, need the bows, on which they climb, be made of durable material and be securely anchored to the ground.
Suitable or not - what you should pay attention to
Material, size and anchorage: That's what matters when it comes to rose arches. Of course, the price also plays a role. Rose growers recommend it, not to save in the wrong place: Expensive bows are usually better and more durable than cheap ones. The arches should always be anchored in concrete foundations, because the plants get heavy and a densely covered arch has to withstand a lot of wind pressure.
Post anchors must be used with wooden arches, so that the wood has no direct contact with the ground (see drawings). The width should be at least 160 cm, so that the passage remains free, even if shoots grow inward. Metal bows are the most durable. Steel tubes or round rods are used, which are mostly galvanized and powder-coated. But there are also arches made of round rods, where rust is desired. A "Arcoflor" by Bekaert, Double arch made of tubes and wire mesh, 230 cm high, 130 cm wide, 157 Euro.

The classics for arches are without a doubt roses. But all other climbing plants are also suitable for planting and are a magnificent ornament individually or in combination with others.
Ivy and pipe bindweed thrive in the shade, for sunny to semi-shady places are honeysuckle varieties, Climbing hydrangeas and clematis beautiful, in full sun feel trumpet flower, Radiant pen and Akebie well.
So that the arch is also densely overgrown from below, you can see annual climbers like nasturtium, Plant bell vine or morning glory.
How stable the rose arch needs to be, depends on the growth and weight, that a plant develops. Wisteria and climbing hydrangeas need very stable arches, weak-growing clematis- and honeysuckle varieties as well as annuals also come with slight, filigree climbing aids well.
