The message
from Judy Rigby contains these words:

Actually, you
don't even need to say it out loud which enables you to maintain a
facade of sanity amongst any humans in earshot ... just *think* it at
the plant with sufficient force & direction & the message gets across
...

It works so well, that I never plant anything, or tend it, without
thinking a silent positive encouragement to it. Don't know how it works
but it does make a difference.

Janet.
