The timeline for mycorrhizae to start working can vary depending on several factors such as the plant species, growing conditions, and the specific mycorrhizal species involved. However, in general, mycorrhizae begin their work immediately after application to a growing plant root.
Once the mycorrhizae are introduced to the root system, they start establishing a symbiotic relationship with the plant. This process typically takes about four weeks. During this time, the mycorrhizae colonize the root system and form specialized structures called mycelium, which extend into the surrounding soil.
The mycelium of mycorrhizae acts as an extension of the plant’s root system, greatly increasing its ability to absorb water and nutrients from the soil. This enhanced nutrient uptake is one of the main benefits of mycorrhizal associations.
After the initial establishment phase, it generally takes around eight weeks for the benefits of mycorrhizae to become visible to the grower in comparison trials. This timeframe allows for the mycorrhizae to fully establish their presence in the root system and for the plant to start experiencing the positive effects of this symbiotic relationship.
It is worth noting that the specific benefits and visible effects of mycorrhizae can vary depending on the plant species and growing conditions. Some plants may show more noticeable improvements in growth, nutrient uptake, and overall health, while others may exhibit more subtle changes.
In my personal experience as a horticulturist, I have seen the positive impact of mycorrhizae on various plants. For example, when using mycorrhizal inoculants in vegetable gardens, I have observed improved root development, increased yield, and enhanced resistance to stress factors such as drought or nutrient deficiencies.
To summarize, mycorrhizae start working immediately after application to a plant root and take about four weeks to establish the symbiotic relationship. It generally takes around eight weeks for the benefits of mycorrhizae to become visible in comparison trials. However, it’s important to keep in mind that the timeline and specific effects may vary depending on the plant species and growing conditions.
