Spider Mites on Arborvitae
Posted: June 4th, 2021, 11:01 pm
We have a row of 32 Arborvitae that I planted three years ago as 5-6 foot plants. They are now between seven and nine feet.
This week I noticed two were a bit bronzey green looking and I started to do some reading. That was when I learned about Spider Mites.
I have read thru some old threads and wanted to see if there is any updated guidance since these threads Morhpeus posted back in 2012..thanks in advance....

Soap also kills spider mites--a spray of 1 tsp of any (not anti-bacterial) soap in a gallon of water sprayed on the trees will kill any mites that live there. It's not going to kill the eggs, however, so they'll come back, but if you keep it up you can keep the population very low.
A few drops of orange oil or pine oil simply make the kill more certain, but soap should take them out all by itself.
This also works with aphids and thrips
