Pro-Mix HP Mycorrhizae is – The Best Planting Soil Mix For Okanagan Gardeners because of its a high porosity (HP) peat-based growing medium containing, beneficial ingredients. “Myco” – “rhiza” literally means “fungus” – “root” and describes the mutually beneficial relationship between the plant and root fungus (mycorrhizae is the plural form of mycorrhiza). These specialized fungi colonize plant roots and extend far into the soil. Mycorrhizal fungal filaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than the roots themselves.


PRO-MIX HP MYCORRHIZAE HP – High Porosity
With its lightweight granular content (perlite) this soil mix provides a great growing environment with a significant drainage capacity, increased air porosity and lower water retention. The added benefit of fibrous peat moss and coarse perlite makes this formulation ideal for gardeners who require a superior-quality product adapted to their needs for watering flexibility.

Undisturbed soils are full of beneficial soil organisms including mycorrhizal fungi. Many common practices can degrade this potential of soil. Tillage, removal of topsoil, erosion, site preparation, compaction, fumigation and invasion of weeds are some of the activities that can reduce or eliminate these beneficial soil fungi. Scientific studies indicate mycorrhizal populations are slow to recolonize naturally, therefore, reintroducing mycorrhizal fungi in areas where they have been lost or in artificial growing media can dramatically improve plant performance with less water, fertilizer and at a reduced cost.

The spore of mycorrhizal fungi germinate in the soil and make their way to the nearest roots. The roots are then colonized by the fungi, and mycorrhizae are established. The fungi penetrate the root, and create an internal network of fungal structure inside the root cells, where the plant and mycorrhizae exchange sugars and nutrients. Finally, the structure of fungi continue to develop outside the roots forming an extended network of fine filaments which cover up to 700 times more soil area than the plants own roots. This secondary root system draws in extra beneficial nutrients and water, supporting a plant for its entire lifetime.
