Concrete wire meshes, or remesh, have become widely used by gardeners Concrete or reinforcing wire (remesh) is a construction material that is very affordable and can be bought at hardware stores, or similar, for a very low cost. Although wire meshes usually bend, they are very strong, long-lasting and resistant. This features (in addition of its price) have made it an option that most gardeners resort to when they want to make the most of reduced spaces and try vertical gardening. It is known that vertical training offers lots of improvements compared to simply letting plants grow freely over the ground. Installing vertical gardening structures may take some hard work, but results are totally worth it, since they make maintenance a lot easier and provides you of a better quality final product, which have less probabilities of contracting diseases at some point in the growth process. Even harvesting becomes faster; however, some materials for vertical gardening work better than others. Concrete wire meshes can come in three different presentations: 100 feet flat panels or 50\/ 100 feet rolls. All of them are 5 feet wide, and the cheapest tends to be rolled one. Although this material may bend, to flatten already rolled portions of wire meshes is almost impossible and takes lot of effort and time. That is why flat panels are used for trellising and fencing, and rolls, to build cages or towers. Which one to use? This will depend on your requirements and on the plants you are willing to grow. Like aforementioned, rolls are great for building cages to train several types of vegetables and other plants, such as tomato, or even to contain berries. Because of the standard width of wire meshes, these cages should be 18 inches (45 cm) in diameter, and as tall as you prefer (according to the type of plant you want to cage). Cages are mostly used to train tomatoes, but you could also try to grow eggplants, zucchini and cucumber using this system as well. However, this is not very recommended, since losses because of rotten crops you cannot find (because they are hidden inside the bush) may increase. To extend the production season, as well as protecting plants from bugs and pests, can be achieved by covering cages with plastic sheeting, creating a sort of mini-greenhouse. In the other hand, wire meshes flat panels are ideal for trellis training. It ends up being a little more laborious method (because it needs a sturdy support structure), but tends to offer better results. You can either place the panel like a wall and use very deeply nailed in the ground poles as backing, or well, to go for an A-framed arrangement, which works amazingly for cucurbits. With this technique you will have less product losses and an easier and faster harvest, since you will not have to be probing inside a bush to find fruits. In spite of its resistance and apparent efficiency, using wire mesh is not recommend in hot zones, since when this material heats up, it may burn your plants vines and crops. Another point is necessary to remark is that it might not offer so good results in massive productions, in which it is better to use plastic trellises for training.
