I have a perennial sun flower that had red spider mites last year. I had to cut the plants back mid summer, I am noticing they are starting to come back this year again. How can I get rid of them, the soapy water didn’t seem to help last year. Thanks in advance

Just plain soapy water is not going to kill spider mites.  Even insecticidal soap doesn’t work well against them.  Neem oil is what I would suggest.  We sell it as a product called “Bon Neem” which is a combination of pyrethrin and neem oil.  You’ll need to thoroughly drench the plants when spraying and spray once a week for 3 weeks to insure control.  Pay particular attention to the undersides of the leaves when spraying.
