How to Put Mycorrhiza in Already Planted Trees

Mycorrhiza are beneficial fungi that can form a symbiotic relationship with tree roots. This partnership can improve soil structure, increase nutrient absorption, and enhance a tree’s resistance to disease and environmental stress.

Assessing the Need for Mycorrhiza

Before adding mycorrhiza to already planted trees, it is important to assess the condition of the soil and the health of the trees. If the soil is already rich in organic matter and the trees are thriving, then adding mycorrhiza may not be necessary.

However, if the soil lacks nutrients or is compacted, mycorrhiza can be beneficial. Additionally, if the trees are showing signs of stress, such as yellowing leaves or stunted growth, mycorrhiza can help improve the tree’s health.

Choosing the Right Mycorrhiza

There are many different types of mycorrhiza, each with its own set of benefits. Some mycorrhiza are specialized to help trees absorb specific nutrients, such as phosphorus or nitrogen, while others can improve water uptake or disease resistance.

When selecting mycorrhiza, it is important to choose a strain that is compatible with the trees and soil in question. It is also important to purchase mycorrhiza from a reputable source to ensure that it is a high-quality product.

Applying Mycorrhiza

There are several methods for applying mycorrhiza to already planted trees:

1. Mix Mycorrhiza with Soil

This method involves mixing mycorrhiza with soil and then adding the mixture to the planting hole or around the tree’s roots. It is important to follow the manufacturer’s instructions for application rates and to avoid over-application, as too much mycorrhiza can harm the tree.

2. Apply Mycorrhiza as a Root Dip

This method involves dipping the tree’s roots into a solution of mycorrhiza and water before planting. This ensures that the mycorrhiza is in close proximity to the tree roots and can begin forming a symbiotic relationship immediately.

3. Inject Mycorrhiza into the Soil

This method involves injecting mycorrhiza directly into the soil using a specialized tool. It is important to follow the manufacturer’s instructions for application rates and to avoid injecting mycorrhiza too close to the tree’s roots, as this can damage the roots.

Monitoring and Maintenance

After adding mycorrhiza to already planted trees, it is important to monitor the trees’ health and growth. If the trees show signs of improved health and growth, then the mycorrhiza is likely benefiting the trees.

It is also important to maintain proper soil conditions, such as avoiding over-fertilization or over-watering, to ensure that the mycorrhiza can form a healthy relationship with the trees.

Conclusion

Mycorrhiza can be a valuable tool for improving tree health and growth. By assessing the need for mycorrhiza, choosing the right strain, and applying mycorrhiza using an appropriate method, already planted trees can benefit from improved soil structure, nutrient absorption, and disease resistance.
