Thuja is a beautiful ornamental plant. It gained its popularity due to the fact that it can be cut, creating beautiful figures from foliage. However, any thuja disease can instantly destroy everything that the gardener has made of her. Despite the fact that this small tree is quite unpretentious to the owner's care, as well as to planting, there are many pests that are always in a hurry to feast on a beautiful plant. Here we will consider the most popular thuja diseases, as well as methods of dealing with them and prevention.
So, the most common disease not only in the tree in question, but also in many others, is brown shoots. In early spring, when the young sprouts of the tree are just beginning to appear, they acquire a brownish tint. This means that your thuja has earned itself a fungal disease. Such shoots should be removed immediately so that the disease does not spread. For prevention, ordinary limestone is used, it is dug up to the root system. In addition, the drug "Fundazol", diluted at a concentration of 0.2 percent, helps a lot. They should spray the tree every two weeks until October. Howeverif it was possible to remove the shoots and get rid of the disease, then this operation is not necessary at all.
The next common thuja disease is called false shield. It lies in the fact that small yellow ulcers form on the trunk of the plant, which will grow if certain treatment is not started. Karbofos, Aktellik or Rogor help here. It should be noted that these same drugs are used when aphids attack your thuja. These are small insects of gray or brown color. When their colony grows, they are covered with a silvery wax-like dust. As a result of the aphid attack, the foliage of the plant turns yellow and subsequently falls off.
Another thuja disease manifests itself in the fact that the top of the tree begins to turn yellow, the foliage falls off, and the plant gradually dies. At the same time, you do not observe any ulcers on the trunk or blanching of the shoots. In addition, aphids did not attack your thuja. Sometimes this happens, and this is the result of poor care. The fact is that the root system performs several functions. One of them is to deliver various nutrients from underground to the trunk and crown of the plant. If the thuja dies, this function is impaired. This can happen for two reasons. In the first case, thuja disease manifests itself due to the fact that its root system began to rot. This happens when groundwater rises high and supplies a certain amount of moisture. The owner, of course, does not even know about it.and additionally water the plant. The root system rots due to excess moisture. In the second case, the disease is due to a fungal disease, which was described at the beginning of the article. And the methods of dealing with it are appropriate.
Thuya danica is more often exposed to various diseases, since it is the most popular among the other species of this plant. Although it is a hardy tree, fungi and pests can kill it. Therefore, do not delay treatment if the disease has already overtaken. And ideally, it is better to carry out prevention.
