Re: Canola as a horticultural oil

Well Don,
Interestingly another list I belong to about Orchids has had a thread going
on oils ( from Canola to almost motor oil :>} ).  The general opinion is
that damage to plants occurred when an oil is sprayed on when the plant is
to hot, such as mid-day. Everyone suggested spraying in the later evening or
the early morning,  Also it was mentioned that even Nem oil will cause
damage if applied when hot.
I plan to try Pam on a couple of plants late in the day then rinse them off
during the morning watering.
Seems like a good idea to me and Costco sells Pam for a song.
