Who else wants healthy trees? A guide to deep root fertilization
Deep root fertilization is a popular technique arborists use to promote tree growth in areas where trees may not have access to adequate nutrients. It is a great way to give your struggling trees a boost. Keep reading to learn about deep tree root fertilization, its benefits, and signs of deficiencies.
Deep Root Fertilization: An Overview
- Deep root fertilization is a tree care technique that involves the application of fertilizer to the roots of trees and shrubs. This procedure can be done by injecting fertilizer into the soil or applying it directly to the root system. The main purpose of deep-root fertilization is to enhance the nutrient uptake of trees and shrubs, leading to improved growth, health, and productivity.
How Deep Root Fertilization Works?
- Deep root fertilization involves the delivery of fertilizer directly to the root system of trees using specialized equipment such as soil probes. The nutrients applied by this method are precisely absorbed where they are needed and are immediately available to the tree. Once the fertilizer is injected into the soil, it gradually spreads and becomes available to the entire root system.
Trees typically have extensive root systems that can spread out two to three times the width of their canopy, making it challenging for surface fertilization methods to provide adequate nutrition. However, deep root fertilization promotes the development of a robust and healthy root system by distributing nutrients to the entire root system.
The Benefits of Deep Root Fertilization
- Deep root fertilization offers several benefits for trees by delivering essential nutrients like phosphorus and iron to the roots. In addition, this method provides trees with an immediate boost of nutrition, promoting their growth and overall health. Unlike surface fertilization methods, deep root fertilization goes straight into the soil without runoffs, making it an environmentally safe option.
Moreover, injecting fertilizer under pressure also helps to aerate the soil, allowing for better water and air circulation around the roots. Furthermore, deep root fertilization helps trees to better defend against pests and diseases by strengthening the root system. A healthy root system enables trees to absorb more water and nutrients and withstand better stressors such as drought, extreme temperatures, and insect infestations.
The Right Time For Deep Root Fertilization
- The right time for deep root fertilization is usually in the spring and fall. In the spring, it supports the growth of new leaves and branches, while in the fall, deep root fertilization can help promote root development, allowing trees to withstand winter conditions better. However, deep root fertilization can be done at any time of the year if the soil is not saturated or frozen.
Signs Your Tree Needs Deep Root Fertilization
Deep root fertilization can be a beneficial treatment for trees that show signs of nutrient deficiencies or stress. Opt for root fertilization if your tree shows the following signs:
- The tree is not growing well
- It has smaller or fewer leaves than usual
- It shows signs of branch dieback
- It has discolored or chlorotic leaves
However, various factors, such as soil compaction, lack of nutrients, root damage, or pests, can cause these symptoms. It is essential to consult with a tree care professional to determine the underlying cause of these symptoms and whether deep root fertilization is an appropriate solution. A certified arborist can evaluate your tree’s health, conduct soil tests, and recommend the best action to improve its overall health.
