In Lapeer, Michigan, where summer dry spells can stress trees, mycorrhizae fertilizer offers a natural solution for improving drought tolerance. Mycorrhizae are a beneficial group of fungi that establishes a mutually beneficial relationship with plant roots. The fungi attach to tree roots and as the fungus grows the size of the plant’s root system is effectively increased.
The extensive network of fungal hyphae significantly increases a tree's ability to absorb water from the soil, acting as a secondary root system. This enhanced water uptake can help trees in Lapeer withstand periods of drought, reducing the need for frequent watering and improving overall tree health.
Research has shown that plants colonized by mycorrhizal fungi have better growth and reproductive response under water-deficit conditions compared to those without. The symbiotic relationship allows trees to regulate their stomatal aperture more effectively during drought, avoiding excessive water loss while maintaining essential functions.
Mycorrhizae fungi can be spread in a planting hole as a dry powder. For trees that are already planted the mycorrhizae can be mixed with water and injected into the soil. The mycorrhizae can be injected alone or mixed with fertilizer to give the tree an added boost.
For Lapeer's urban trees, which often face challenging growing conditions, mycorrhizae can be particularly beneficial. The fungi help trees tolerate environmental extremes, including soil compaction and pH imbalances often found in urban settings. This makes mycorrhizae an invaluable tool for ensuring tree success in Lapeer's diverse urban and suburban landscapes.
By incorporating mycorrhizae fertilizer into tree care practices, Lapeer residents and urban foresters can create a more drought-resistant urban forest. This not only enhances the beauty of the town but also contributes to a more sustainable and resilient urban ecosystem.
