|What is a good all purpose strong spray for Alberta Spruce spider mites, Junipers, Hollys and Aborvite also in garden. Pls advise Thanks CARYL|
|Insecticidal soaps will control spider mites, and you can use it on all of your ornamentals except the spruce (oil based insecticides can remove the sheen on the foliage and cause it to change color). For your spruce, you might want to use malathion or other registered miticide.
Best wishes with your landscape!
