How to Put Mycorrhiza in Already Planted Trees

Mycorrhiza is a symbiotic association between fungi and plant roots that is mutually beneficial. The fungi provide the plant with nutrients such as phosphorus and nitrogen, while the plant provides the fungus with sugars. Adding mycorrhiza to already planted trees can increase their growth, nutrient uptake, and disease resistance. Below are some steps on how to put mycorrhiza in already planted trees.

Step 1: Choose the right mycorrhiza species

There are two types of mycorrhiza: ectomycorrhiza and endomycorrhiza. Ectomycorrhiza forms a sheath around the roots of trees and shrubs, while endomycorrhiza forms structures called arbuscules inside the roots of most plants. It is important to choose the right mycorrhiza species that matches the tree species you plan to apply it to. For example, if you want to apply mycorrhiza to a conifer tree, you should choose an ectomycorrhiza species. If you plan to apply it to a deciduous tree or shrub, an endomycorrhiza species is recommended.

Step 2: Prepare the soil

Before applying mycorrhiza, it is important to prepare the soil. First, remove any weeds or debris from the area around the tree. Then, loosen the soil around the tree to a depth of about 3-4 inches. This will help the mycorrhiza spread more easily throughout the soil. If the soil is compacted, it may be a good idea to add compost or other organic matter to improve aeration and water retention.

Step 3: Apply the mycorrhiza

Once the soil is prepared, it's time to apply the mycorrhiza. There are several ways to do this, including mixing the mycorrhiza powder with water and pouring it around the tree or using a root dip or gel. Regardless of the method you choose, be sure to follow the instructions provided by the manufacturer. In general, you should apply about 1-2 teaspoons of mycorrhiza powder per tree, but this can vary depending on the size of the tree and the concentration of the mycorrhiza.

Step 4: Water the tree

After the mycorrhiza is applied, it is important to water the tree generously. This will help the mycorrhiza spread throughout the soil and establish a symbiotic relationship with the roots of the tree. Be sure to water the tree regularly after application, especially during dry periods. This will help the mycorrhiza to continue to thrive and provide benefits to the tree.

Conclusion

Adding mycorrhiza to already planted trees can be a great way to improve their growth, nutrient uptake, and disease resistance. By following the steps outlined above, you can ensure that your trees are receiving the right type of mycorrhiza and that it is being applied correctly. With the right care and attention, your trees will benefit from this symbiotic relationship for years to come.
