Fertilization supplements soil nutrient levels, reduces stress by balancing the pH, and facilitates root growth. Tree and shrub growth also requires soil health management, which entails mulching, proper and regular soil aeration, testing, and watering. In Northwest Houston, the soil is characterized by poor drainage, high alkalinity, probable soil compaction, and the potential lack of essential nutrients. Fertilization and management of soil health are paramount for tree and shrub growth.
Understanding Soil Composition and Its Impact on Plant Health
The ideal soil composition determines the ability of trees and shrubs to access nutrients, grow, and thrive. Different elements, such as soil structure, pH levels, and texture, play different roles.
Soil structure is one of the key elements that determines soil health. It refers to the arrangement of soil particles and affects root growth, soil aeration, and water movement.
Soil pH levels are also important components in plant growth. The pH affects nutrient availability, aluminum toxicity, and microbial activities in the soil. Slightly acidic and neutral soil supports micronutrients like N, P, K, mg, S, and Ca, while Fe, Mn, Cu, B, and Zn thrive in slightly acidic soil.
Soil Texture is another component worth noting. It refers to the proportion of clay, silt, and sand in the soil for the balance of nutrients. Texture determines the soil's capacity to hold and cycle nutrients, retain water, and enable root penetration for healthy trees. Sandy soils have fast soil drainage properties, causing water stress. They also do not hold nutrients and enable easy root penetration but with weak plant support.
Clay is compacted soil with poor drainage. It can hold nutrients because of its high cation exchange capacity and has difficult root penetration because of compaction. Loamy soil is well-drained and provides ideal retention of water and nutrients and root penetration, thus ensuring healthy trees and shrubs.
Essential Nutrients for Trees and Shrubs
Nitrogen (N) is the main component of oxygen, amino acids, and enzymes, which help in the production of chlorophyll. It facilitates robust plant growth. When Nitrogen is adequate, trees experience vigorous growth of lush green and healthy foliage. The organic and inorganic sources are urea, compost, ammonium nitrate, blood meals, and manure.
Phosphorus (P) is the key component of plant RNA and DNA, which enable the transfer of energy through processes like respiration and photosynthesis. P also helps in root development. When phosphorus is adequate, plants have stronger roots and facilitate the development of flowers and fruits. The sources include super and triple phosphate, rock phosphate, and bone meal.
Commonly known as K, potassium helps plants resist stress and improve their overall health. These effects are possible because of the ability of K to regulate the movement of nutrients and water, soil enzyme activity, and improve plant's resistance capability to disease and cold. Adequacy of K ensures the growth of healthy trees and shrubs that can survive drought and winter. Sources include kelp meal, wood chips, potassium sulfate, and chloride.
Identifying Signs of Nutrient Deficiency
Signs of nutrient deficiency vary according to the plant species and severity of the deficiency. Below are a few pointers of soil health indicators that may prompt fertilization.
Nitrogen deficiency is one of the identifying signs of nutrient deficiency. It is characterized by the yellowness of the older leaves, commonly known as chlorosis. Sometimes, the leaves fall off prematurely, resulting in stunted plants.
Phosphorus deficiency can be identified with leaves turning dark green or purplish. Flower and fruit development is also delayed, and the tree experiences stunted growth.
Magnesium deficiency causes curling of leaves, premature falling, and yellowness of in-between leaf veins.
Potassium deficiency is characterized by the yellow or brown discoloration of leaf margins and tips. The plant develops weak stems and branches and is more susceptible to cold and disease.
Iron insufficiency causes dark green veins, and new leaves will look whitish. Less manganese causes brown spots on leaves and checked patterns in veins.
Choosing the Right Fertilizer
When selecting fertilizer for different species of trees and shrubs, you should consider all the different factors.
The objective of fertilizing is the first factor you should consider. The objectives of fertilizer application are to supplement nutrients and promote the growth and development of flowers and fruits. Using a soil testing kit or plant tissue analysis, you can determine the nutrient levels. Remember that fertilizing does not automatically correct issues like stunted growth or leaf discoloration. Implementing objective fertilizing means avoiding routine fertilizing.
You should also select the right type of fertilizer based on testing results: The soil testing process and plant tissue analysis should inform the fertilizer grade. Often, fertilizer recommendations are based on the quantity of nitrogen more than other nutrients because they are needed in higher quantities for colorful plants. You can consult a knowledgeable team for guidance on appropriate fertilizer for healthy plant development.
Other factors include the timing of fertilizer application, the amount of fertilizer, appropriate application methods, and applying it to the right areas of the plant.
Between synthetic and natural fertilizers, it is advisable to use organic soil products to avoid issues like blockage of nutrient uptake, damage to the root system, and harm to beneficial microorganisms. Biochar, compost, wood chips, and leaves can be used as natural fertilizers.
Best Practices for Fertilizing Trees and Shrubs
Timing is crucial for fertilizing trees and shrubs. Apply fertilizer on moist, warm, and well-aerated soils to increase nutrient uptake. Carry out soil tests to determine the soil temperature before application. Ensure that you divide the fertilizer into small portions and apply it at different times to maximize the use of nutrients, especially nitrogen, and reduce dangerous materials in the environment.
The application methods used play a pivotal role in the success or failure of the fertilization process. The methods of application depend on the type of fertilizer. If you are using granulated fertilizer, for instance, use the broadcasting method and ensure you apply equal amounts on all sides. Water the ground before and after application to increase absorption into the roots. Apply fertilizer only on loose, well-aerated soil.

For liquid fertilizers, you can pour directly on the soil surface or on top of organic mulches. Irrigate well to avoid overconcentration.
Precautions are also important in this process: Be keen on the fertilization timing and ensure you apply fertilizer in bits to avoid wastage, root rot, and soil pollution. Also, embrace regular soil testing and care.
