5 - Problems and Solutions Related to Mycorrhizae
Although mycorrhizae offer numerous benefits to bonsais, certain problems can arise, affecting this symbiotic relationship. Fortunately, there are solutions to address these issues.
Identification of Common Problems
- Symbiosis Failure: Lack of growth, yellowing leaves, or weak root development may indicate insufficient mycorrhizal symbiosis.
- Suboptimal Conditions: Poorly drained substrate, inappropriate pH, or excessive fertilization can inhibit mycorrhizal formation.
- Fungal Diseases: Some fungal diseases can affect mycorrhizae, hindering their ability to support the tree.
Appropriate Solutions and Treatments
- Improvement of Substrate: Ensure that the substrate is well-drained and aerated. An adjustment in the substrate composition may be necessary to promote mycorrhizal growth.
- Watering Management: Modify the frequency and method of watering to maintain a moisture balance suitable for the development of mycorrhizae.
- Fertilization Control: Reduce the amount of fertilizer, particularly those high in phosphorus, to encourage mycorrhizal formation.
- pH Adjustment: If the pH of the substrate is too far from neutrality, adjust it to create an environment more conducive to mycorrhizae.
- Treatment of Fungal Diseases: Use appropriate fungicides to treat diseases affecting mycorrhizae, following instructions carefully to avoid damaging the symbiosis.
Prevention of Mycorrhizal Problems
- Regular Monitoring: Regularly examine the roots and substrate for early signs of problems.
- Healthy Cultural Practices: Maintain healthy cultural practices, including careful repotting, to prevent imbalances that could harm mycorrhizae.
In conclusion, although mycorrhizae are generally beneficial for bonsais, careful monitoring and management are necessary to maintain a healthy symbiotic relationship. By identifying and addressing problems quickly, cultivators can ensure that their bonsais continue to benefit from this vital interaction.
