Subject: Re: Oh NO! Spider Mites!
Thanks to all that helped with my spider mite problem!
I tried to raise the humidity, as I do every year. In fact the "skunk
cabbages" are all sitting on trays of water since winter ended, and getting
misted regularly.
I guess you just can't fight the Arizona desert without a greenhouse.
I'm going to give in this year on my "eco-groovy" philosophy and go for the
big guns.
I'm off to get some Pentac.
Many thanks to all!
