your soil Mycorrhizal fungi -- the Secret Ingredient!
Remember that your soil is alive! You may add great fertilizers but
sometimes they may not be able to be taken up by the roots of
the plants. Mycorrhizal fungi help promote a plant's "feeder
roots" which take up water and nutrients in the soil. Territorial
Seed Company says, " Plants demonstrate better vigor and growth,
during their life cycle, leading to better and higher fruit yields."
This has been my experience, too. I sprinkle in small amounts
of the powdered fungi in with all plantings. The will grow and
populate in the soil. Love and Mychorrhizal fungi are the top
2 on my list of gardening tips.

More detailed information from Wikipedia:
A mycorrhiza (Greek for fungus roots; typically seen in
the plural forms mycorrhizae or mycorrhizas) is a symbiotic (occasionally
weakly pathogenic)
association between a fungus and
the roots of a plant.[1] In
a mycorrhizal association the fungus may colonize the roots of a host
plant either intracellularly or extracellularly.
This mutualistic association
provides the fungus with relatively constant and direct access
to mono- or dimeric carbohydrates,
such as glucose and sucrose produced
by the plant in photosynthesis.[2] The
carbohydrates are translocated from their source location (usually
leaves) to the root tissues and then to the fungal partners. In return,
the plant gains the use of the mycelium's
very large surface area to absorb water and mineral nutrients from the
soil, thus improving the mineral absorption capabilities of the plant
roots.[3] Plant
roots alone may be incapable of taking up phosphate ions that
are immobilized, for example, in soils with an basic
pH. The mycelium of
the mycorrhizal fungus can however access these phosphorus sources, and
make them available to the plants they colonize.[4] The
mechanisms of increased absorption are both physical and chemical. Mycorrhizal
mycelia are much smaller in diameter than the smallest root hair.[citation
needed] For this reason they are able to explore
a greater volume of soil and have a much larger surface area for absorption.
Also, the cell membrane chemistry of fungi is different from that of plants.
Mycorrhizae are especially beneficial for the plant partner in nutrient-poor
soils.
Mycorrhizal plants are often more resistant to diseases, such as those
caused by microbial soil-borne pathogens,
and are also more resistant to the effects of drought. These effects are
perhaps due to the improved water and mineral uptake in mycorrhizal plants.
Mycorrhizas form a mutualistic relationship
with the roots of most plant species (although only a small proportion
of all species have been examined, 95% of all plant families
are predominantly mycorrhizal).[5]
Plants grown in sterile soils and
growth media often perform poorly without the addition of spores or
hyphae of mycorrhizal fungi to colonize the plant roots and aid
in the uptake of soil mineral nutrients. The absence of mycorrhizal fungi
can also slow plant growth in early succession or on degraded landscapes.[6]
