Rose trellises in various shapes, colors and sizes are available in every hardware store. However, the required size is not always in stock and some do-it-yourselfers value building such a trellis themselves. This is also possible for people with the proverbial two left hands, because rose trellises are very easy to assemble.

Build a frame out of wood
Before you start building, you should first consider how big the trellis should actually be. Small rose trellises are first screwed together and then fastened, with larger ones the frame must first be set up and then the trellis attached. For larger trellises, use two support beams and one crossbeam, whereby the two support beams must be firmly anchored in the ground - otherwise the whole construction can quickly fall over, for example because the load from a climbing rose that has become very large has become too great. These trellises are usually stable enough to be set up freely. For smaller trellises, a frame made of sturdy wooden slats is often sufficient, which are screwed together in the desired shape (it doesn't always have to be rectangular!) and attached directly to the wall. Make sure that the distance between the trellis and the wall is at least 10, preferably 20 centimeters.
Make a suitable trellis: from wood, wire ropes or reinforced steel mats
Once the frame is complete, you can get to work on the trellis. There are various possibilities: A trellis that is very easy to produce consists of a wooden frame and a reinforcing steel mat that has been flexed to the right shape and size - you can have these cut to size at the hardware store and only have to attach them to the frame at home. Another variant is to simply buy different wire ropes and stretch them into the frame as a trellis. However, both components - both the welded wire mesh and the wire ropes - rust quickly and should therefore be treated preventively. Wooden trellis, on the other hand, can be made of slats that are attached to the frame either in a lattice pattern or simply as cross slats. The wood should also be treated with wood preservatives to prevent rot.
tips
Not only the trellis has to be built as stable as possible - roses in full foliage and bloom can reach a very high weight - the posts must also be firmly anchored in the ground, for example by so-called beam shoes and by embedding them in concrete.
