Not sure what soil fertilization does for your landscape? Essentially, it enhances the quality of the soil on your San Diego Area property, in turn improving the nourishment, growth and health of your trees. The ISA-certified arborists at Coastal Tree Care elaborate on soil fertilization, and why it matters.

Everything You Should Know about Soil Fertilization

  • What is soil fertilization? Soil fertilization is the process of creating optimum soil conditions for promoting the health and vigor of your foliage. A well-balanced soil creates the ideal chemical, biological and physical factors for a thriving landscape. Also, with a proper fertilization program and timely applications, your trees will demonstrate increased resistance to pest infestations and tree diseases.
  • What factors determine the need for soil fertilization? Tree nourishment starts with soil nourishment. However, in order to add the right type and amount of nutrients to your soil, you need to know:
  • The short term and long-term needs of your existing trees and shrubs: An arborist report will offer detailed insights into the type of trees on your property. It will also include tree health assessments, suggested treatments, and potential liabilities or hazards related to their growth or health.
  • The current composition of your soil: A soil analysis will tell you whether your soil is compatible with the needs of the existing trees, as well as any new ones that you want to plant. From water drainage and nutrient retention qualities, to pH levels (acidity / alkalinity) and nitrogen (N), phosphorus (P) and potassium (K) levels, you will get insights into a number of soil-related parameters.
  • What signs tell you that your soil needs fertilization? Routine fertilization programs and timely applications are imperative for maintaining the general wellness of your trees. However, adding soil nutrients becomes necessary if your soil tests reveal any deficiencies, especially in the N-P-K levels. Imbalanced soil nutrition could manifest itself in the form of undersized or discolored leaves, thinning canopies or branch growth rates, and greater occurrence of tree pest attacks or diseases.
  • When should you fertilize? For newly planted trees or trees with root damage (due to construction, relocation or trenching work), it’s important to avoid fertilization until their root system properly re-establishes. Similarly, for mature trees that have a well-developed root system, restrict applications to once every two to three years. Wherever annual fertilization is necessary, schedule your applications in late April to early May, or in October, when fall sets in and plant growth subsides.
