=======================================
Many problems require only thinning
and pruning of damaged wood.
Other problems are not serious enough
to warrant treatment.
Know what you are treating for and
when to treat.
Below are listed key problems to look
for, or action needed, now.
Check the links on our Home Page for
further information on least-toxic
alternatives using
Integrated Pest Management (IPM).
