Add mycorrhizae and beneficial bacteria to your backfill soil when transplanting trees and shrubs

Adding mycorrhizae and beneficial bacteria to your backfill soil when transplanting trees and shrubs is indeed important and can significantly benefit the establishment and long-term health of these plants. Here's why it's recommended:

Improved Nutrient Uptake: Mycorrhizal fungi form symbiotic relationships with the roots of many trees and shrubs. These fungi extend the plant's root system by forming a mycorrhizal network that can explore a larger volume of soil. This increased root area allows for better nutrient and water absorption, especially for nutrients like phosphorus, which mycorrhizae are particularly efficient at obtaining.

Enhanced Stress Tolerance: Mycorrhizal associations can help trees and shrubs cope with environmental stresses such as drought, salinity, and soil compaction. Mycorrhizal networks can improve the plant's ability to access water and nutrients even in challenging soil conditions.

Disease Resistance: Some mycorrhizal species can help protect trees and shrubs against soil-borne pathogens. They do this by competing for resources and releasing antimicrobial compounds, which can suppress the growth of harmful microorganisms in the root zone.

Promotion of Beneficial Bacteria: Mycorrhizal fungi can facilitate the establishment of beneficial bacteria in the rhizosphere (the soil zone around the plant's roots). This enhances the overall soil microbiome, which can contribute to nutrient cycling and improved soil health.

Faster Establishment: The combination of mycorrhizae and beneficial bacteria can promote faster establishment of newly transplanted trees and shrubs. This can reduce transplant shock and improve the overall survival rate of these plants.

Long-Term Benefits: Mycorrhizal associations can persist for the life of the tree or shrub, continually providing benefits for nutrient uptake and stress tolerance as the plant matures.

When adding mycorrhizae and beneficial bacteria to the backfill soil during transplanting, it's important to follow these guidelines:

Use Quality Products: Choose mycorrhizal and bacterial inoculants from reputable sources, ensuring that they contain viable and effective strains.

Proper Application: Mix the inoculants with the backfill soil or the planting hole as per the recommended application rates. Ensure good root-to-inoculant contact for successful colonization.

Avoid High-Phosphorus Fertilizers: High levels of phosphorus can inhibit mycorrhizal colonization, so avoid using excessive phosphorus-containing fertilizers during transplanting.

Provide Adequate Moisture: Mycorrhizae and beneficial bacteria require adequate moisture to establish and thrive. Water the transplanted trees and shrubs as needed to maintain soil moisture.

Protect Roots During Planting: Take care not to damage the roots when transplanting, as healthy roots are essential for successful mycorrhizal associations.

By incorporating mycorrhizae and beneficial bacteria into your transplanting process, you can create a more favorable and supportive environment for the trees and shrubs, leading to healthier, more resilient, and better-established plants.
