fungal associations that conifers enjoy with soil dwelling micro-organisms are
unavailable, and seedling development is inhibited compared with seedlings that are ...

inoculation The introduction of a pathogen to a host plant's tissues.
inoculum The parts of a pathogen that infect plants.
insectary plant A plant that attracts beneficial insects.
Straw works best because it is usually free of weed seeds and disease pathogens. Make sure the material amply covers the area where the top is attached to the trunk (the graft), as it is the most sensitive to cold.
Damping off pathogens can live in these containers. The easiest way to disinfect them is to dip them in a bleach solution for 10 seconds. Use 1 part bleach to 4 parts water. Or use 70 percent rubbing alcohol.
