Re: Milorganite

Connie,
Most of my sources are hard copy and are at work. I just finished
co-authoring a piece on planting for my job. I only go in to the office
2 days a week and can get them together when I am next there. We are
trying to get our planting crews to use the new methods to cut down on
our replacement costs.
I remember a case (ca. 1990-91), from when I lived in Kentucky, of a
mass planting of evergreen azaleas - maybe 30 plants - planted in clay
and amended with all manner of goodies. Five years later, the planting
began to fail. It was spotty problems the first year, expanding the
second. The homeowner had some dug to find the cause. All were circling
in their planting holes!! The probable cause was, at that time, thought
to be that the roots had not been properly spread when the original
planting was done. I don't believe that this was the case as I knew the
person who did the planting, and he was very precise about everything.
After doing the research for the planting piece, I believe the
"flowerpot effect" was the reason. They WERE planted too deeply, though,
which compounded the problem.
