MYCO PAKS Under ideal soil conditions mycorrhizae can extend a plants' root system 25 to 50 times for increased nutrient uptake, increased resistance to drought, less transplant shock and increased overall growth. Spectacular growth responses have been observed in nutrient deficient soils that lack the native fungi when amended with organic mulches and mycorrhizae. Good results also come adding MYCO PAKS to native organically rich soils and potting soils because you are adding 11 different fungi species to really get your roots growing. Add our Kigi Planting Mixes  and Organic Fertilizers for maximum benefits.

How do mycorrhizal fungi work?

Mycorrhizal root system increase the absorptive area of roots 10 to 1000 times thereby greatly improving the ability of the plants to utilize the soil resource. Mycorrhizal fungi are able to absorb and transfer all of the 15 major and micro nutrients necessary for plant growth mycorrhizal fungi release powerful chemicals into the soil that dissolve hard to capture nutrients such as phosphorous, iron, and other "tightly bound" soil nutrients. This extraction process is particularly important in plant nutrition and explains why plants without mycorrhizae require much higher levels of fertility to maintain their health.

Does my soil contain mycorrhizal fungi?

Soils in natural settings are full of beneficial soil organisms including mycorrhizal fungi. Research indicates, however, many common practices can degrade the mycorrhizal potential of soil. Tillage, fertilization, removal of topsoil, erosion, site preparation, road and home construction, fumigation, invasion of non native plants, and leaving soils bare are some of the activities that reduce or eliminate these beneficial soil fungi. In many man-made landscapes we have reduced or eliminated the soil organisms necessary for plants to function without high levels of maintenance.

How to use mycorrhizal fungi Tea Bags?

Once your planting hole is dug place your new plant in the hole then simply place the biodegradable tea bags evenly around the outside roots or root ball, make sure the tea bags remain touching the roots as you fill with soil.

    Posted by Martha on 28th Nov 2020

    As a new gardener, I appreciate the nursery's recommendation of products that help new Korean firs to survive the transplanting, and to thrive. So far, so good; one is settled happily in a permanent home; the other is heeled into a pot until hardscape is completed and its spot readied nearby. Meanwhile, doing great in the pot.
