What Is Mycorrhizae?

Mycorrhizal fungus are beneficial to plants as part of a symbiotic relationship with roots that greatly benefit both fungus and plant alike.Nearly all plant life is dependent on the mycorrhizal association which it is believed began some 460 million years ago and is credited with enabling life to move from water to land. Mycorrhizal fungi grow through the soil by means of hyphae, which are the “roots” of the fungus. These “roots” are extremely filamentous and explore every tiny crack and cranny in the soil to absorb water, and nutrients in solution, and give this solution to the roots of the plant. For this service about 15% of the foods converted by the plant from the energy of the sun is given to the mycorrhizal fungi as it’s only food source. This mutualistic relationship between plant roots and mycorrhizal fungi is an essential link between nearly all plants and their soil environment. Should this food flow from the roots to the fungi be interrupted in anyway the fungi responds accordingly. This is why plants in all stressed conditions benefit from mycorrhizae. Regardless of the cause, i.e., drought, high salt, parasites, negative organisms, etc., mycorrhizae has evolved to protect their food source – the plant. Mycorrhizal fungi are a natural phenomenon – it is a natural and essential part of a complete plant system.

The full story of what effect mycorrhizal roots have on plants are still evolving. To date we know that some plants cannot live without mycorrhizal roots. We also know there are a few well known plants that do not need mycorrhizae, like broccoli, brussels, and cabbage.

Do We Need to Inoculate?

The reason we should inoculate is standard agricultural, nursery and landscape practices have largely ignored what’s going on below the ground and focused on the plant above the ground. Formal ag and horticulture classes have given limited attention to the topic of mycorrhizae – but this is changing rapidly – today it is estimated there are thousands of research studies ongoing on the subject. The real energy that is pushing the topic of mycorrhizae to center stage is the success it is now showing in commercial applications.

Commercially speaking our focus in the nursery industry has been on top growth and quantity. Because of the pressure the typical nurseryman has to turn inventory, little, if any attention, has been given to the natural health of the plant. Today the nursery industry produces plants that look good, but are not naturally complete. To turn inventories and remain competitive the nurserymen uses a host of chemical and management techniques to manipulate plants to grow fast and look good. Plants are quite literally grown in abubble (the greenhouse) and do not develop many of the natural systems they have evolved with and in many cases must have in the real world (the landscape) to thrive and prosper. As a consequent much of nursery stock sold is relatively fragile and can quickly die if not maintained intensively. Thus, much of the reason for so called transplant shock. 

Most will agree that we could use some help for better results with newly planted landscapes which always experience some degree of transplant shock. Generally the reason is poor after care, but heat, time of the year, soil conditions, along with untold other factors also play important roles here. One of the biggest problems is most transplanted plants have little, if any, natural systems working for and with them and the soils they are planted in likely offers little help from a microbial standpoint because it has often been moved around, compacted, and disturbed (grading, fill, etc.) and generally has little, if any, beneficial microbial life.

Inoculating plant roots with beneficial mycorrhiza significantly aids all transplants including trees, shrubs and flower bed results, and even vegetables and forets seedlings, especially under adverse conditions. Today we know that mycorrhizal roots take hold faster – there is little doubt on this fact. Furthermore, we know mycorrhizae and beneficial microbial activity in the soil make sound horticultural sense resulting in better plant health. Research has shown for several decades that mycorrhizal roots improve establishment, nutrient uptake, hardiness and drought resistance, offering reduced fertilizer and fungicide inputs, and increased plant disease tolerance. Recent research is showing that mycorrhizal roots can thrive in high salt environments which have in recent time become more and more prevalent because of severe problems associated with salt water intrusion. Now we are beginning to take serious the natural systems which have been ignored for many decades.We have these perfect systems available to us, but have instead employed billions of dollars in chemicals to control growth and predators. Now is the time to look at the natural systems that lie below our feet – the soil flora, and especially, mycorrhizae.

It’s a Natural Approach

So, how can we treat plants with mycorrhizae? The proven methods include root dips, soil amendments, drenches, root injection and vertimulching. Instead of a single minded approach consider a Natural approach which includes a host of beneficals naturally reserved for healthy ground and roots – complex compounds of fungi, bacteria, minor nutrients, water holding elements, organic matter, and minerals. What do we treat the plants with? If this approach makes sense lets consider a cocktail for plants coming out of nurseries or starting up in disturbed ground. Instead of a simplistic approach (chemical) lets use a systemsapproach (natural systems, that is). In fact, forget the cocktail, lets give the transplant a banquet:

Ectomycorrhizae– Diverse species

Trichoderma-Numerous diverse species – soil disease fighting fungi

Beneficial Bacteria – Nitrogen fixing, Phosphate solubilizing, and Growth Promoting Bacteria

Biostimulants – Over a hundred from Sea Kelp Extract, Humus, Yucca Plant Extract

Amino Acids – Buffers heavy metals and high salts and improves microbial activity in the soil.

Vitamins & Enzymes – Essential for chlorophyll production, cell division, transpiration and respiration.

Water Management Gels – Agricultural grade to slow release water and nutrients.

All are university proven, commercialized, and inexpensive – each loaded with benefit for the plant and soil environment. Especially when transplanting a world of difference is available which provides dramatic results in establishment.

If You Transplant – Put Mother Nature to Work

DIEHARD™ mycorrhizal inoculants are formulated as transplant soil amendments, injectables, and bare root preparations to inoculate landscape trees and shrubs, flower beds, established trees and shrubs and bare root seedlings with live beneficial mycorrhizal fungi. The inoculant contains highly selected strains of low host specificity endo- and ectomycorrhizal fungi that will quickly colonize the roots of new transplants to provide the best possible conditions for the roots to become mycorrhizal during the establishment period and beyond. The mycorrhizal inoculants are combined with humic acids, stimulants, beneficial bacteria, soluble sea kelp, yucca plant extracts and organic soil conditioners to promote rapid root development. To reduce transplant stress and watering maintenance, and to slow release all soluble components of the formulation Horta-Sorb® water management gels are added to complete the package.

Conclusion

DIEHARD™ inoculants, including all the other families of growth-promoting ingredients are an investment that can return its cost several times over in a number of ways. Just think how you would feel about your projects when you have all the goodies Mother Nature has to offer working for you. Stressed plant materials are the norm when transplanting. Give them all we’ve got when we transplant – it’s the right thing to do. It’s the responsible thing to do to achieve sustainable production for plants and the environment.
