Hi again Kay,

About the caffeine being a germination inhibitor....I assume there is still
caffeine in coffee grounds.  The last 2 years I've spread coffee grounds
around my new "northwoods" garden trying to lower the pH to create the kind of
environment found further north in Minnesota so that I can grow the
wildflowers found up there.  (I also use pine needles and have suceeded in
lowering the pH quite a bit without using elemental sulfur or iron sulphate
but I have watered with Miracid a few times).

Have I unwittingly reduced the chance of my wildflowers getting established
because their seeds won't be able to germinate?  Are some species more
sensitive to this than others?

What a sad thought!

Thanks again,
