Tree Fertilization for Better Health of City Green Spaces
Tree fertilization promotes faster growth in trees that suffer from various nutrient deficiencies. Even windbreaks that grow in much better conditions than your average urban tree often have insufficient access to the required micronutrients. This can manifest itself in various symptoms, chief among them being off-color leaves. If there is a deficiency, a plant has a much decreased capability to resist pests and infections, and timely tree fertilizing is therefore highly beneficial.
The plants that grow in city surroundings face a number of serious issues that can aggravate the problem. Their growth can be impaired by many factors including:
- Large areas of concrete (pavement, buildings, etc.)
- Excessive pruning
- Denser soils
- Noise and vibration from nearby construction sites
- Toxic transport and industrial emissions, etc.
Moreover, tree owners sometimes use decorations that limit moisture and nutrient availability for the plants, such as sod covers. That's why green spaces can deteriorate without tree fertilization. If you notice the common symptom of off-color foliage in your trees, chances are that a tree fertilizer could easily solve this problem.
However, it is important to select compounds very carefully. There are organic and inorganic types and a multitude of different variations within each type. It's important to choose tree fertilizers according to the condition of a particular tree and the soil in which it grows.
A soil sample is usually taken to determine its micronutrient composition. According to the results of this test, a tree fertilization plan is compiled to balance out any deficiencies; therefore, there is no such thing as a perfect tree fertilizer for every species and soil condition.
The majority of tree fertilizers contain the three most important elements that trees often miss out on, which are nitrogen, phosphorous and potassium. What differ are the quantities of these elements in each product, as well as their additional components. As soon as tree fertilization requirements are found, the compounds should be used immediately to prevent further decay.
Different species may have highly dissimilar root systems. Moreover, feeding roots of the same species may be located differently depending on the soil type. It's important to know the situation you're dealing with. That's why having a professional arborist by your side is beneficial in finding the right approach, and can greatly increase the effectiveness of fertilizers, resulting in healthy, beautiful trees.
