When a vertical garden is perfect is obvious (enlazado con el otro artículo): the plants have an intense green color and a leafy and lush appearance, without hollows or gaps between them, or dear leaves. In short: it is teeming with life.

However, sometimes vertical gardens don’t reach this status. This affects not only its appearance, but also the benefits it can bring both to the environment and the human beings. Therefore, it is something that must be solved as soon as possible.

First of all, it has to be found what is causing the vertical garden dies, dries or doesn’t bloom. Usually is because one of the five following reasons.

vertical garden die

Five reasons why vertical gardens die
1. Lack or overload of nutrients
If the leaves are not green, it is probably is due to a mismatch in the amount of nutrients that plants need. Like any living being, plants need food and get nutrients from different sources. In this case, the color of the leaves is what gives us the clue that something is not working, and probably we will have to adjust again the proportions of nutrients to fertilize the vertical garden.

2. Shortage or excess water
Another of the most obvious clues that the garden is not going well is the dry appearance. In this case, logically, what happens is that the plants aren’t getting enough water. Rather less obvious but equally harmful for some species is the excess of water, that can drown the plants and inhibit it development. Either by excess or shortage of water, is important to have information about which is the optimal amount for the plants of the garden.

3. Lack or excess light
Plants can’t live only with water and fertilizer, they also get big part of the nutrients they need from the light. This, depending of the place where the garden is placed, can be natural (solar light) or artificial (electric light). In any case, there are plants accustomed to direct sun, which will need a huge amount of light to live, but there also are plants that naturally develop in the shadow, and which can get burned if we expose them directly to the light.

4. Water chemistry
The amount of moisture is not the only aspect of water to be controlled. It also influences its quality. Parameters such as the amount of mineral salts, the acidity, the pH or the conductivity of the water are decisive for the plants wellbeing. For example, the pH level a plant can tolerate depends of its specie.

5. Pests or diseases
Pests are one of the more common problems, both in vertical and traditional gardening. They are one of the most annoying threats and, in many cases, can cause diseases which produce the progressive death of the garden.

Nevertheless, pests are closely related to the four points mentioned above. This means that if a vertical garden is healthy, and its amounts of water, light and nutrients the plants get are well adjusted, is way less probably it is affected by pests. This is why, the best way to face pests is, first of all to apply the remedy and kill them, and then look for its source and solve the problem from its origin.
