Toni - Thanks for the information.
I truly cannot remember where I read about cedar, but it is very probable that the writer thought the problem s/he was seeing was due to the kind of mulch that was used at that time in the garden, but it was really another variable that caused the problem s/he was seeing. That happens a lot when we are trying to figure out what may be causing a problem in our gardens.
There are no big box stores up here, so I get what I can glean ...
It's good to know that I don't have to worry about cedar, now.
That's what I like about this site. When people share their actual experiences, I can filter out a lot of what I have read elsewhere.
Thanks, again.
Smiles,
Lyn
