Yes, and it is important to most plants in general because it keeps the surface of the soil from drying out too quickly.

Yes. Less than that and you are approaching the granularity of compost with does not provide enough aeration, percolation -- and provides a home for the seeds of weeds to grow in. Larger than 1 inch (say, 2 inch or larger) provides too much aeration and allows too much moisture to escape via evaporation.

Applied this way, mycorrhizae need only be added once. The population will then remain with the plants unless the soil is deeply treated with an extreme fungicide. Note also that many soils already contain mycorrhizae: the gardener simply needs to put mulch on the surface so that the population can flourish.

Yes. It is not an exclusive partnership.

Never use mulch or compost unless it has been thoroughly composted.
