Becky .... I am sorry. Your hint was about aphids and I changed it to mites ...
I may be dealing with a different species of aphids and spider mites than you find in your garden and that's why just water does the trick for me. However, if just spraying with water didn't solve the problem, I would certainly add soap to my spray routine because of all of the positive feedback I've read in this thread.
Thanks for the tip.
Smiles,
Lyn
