does this sound like spider mites?
Last year my Meyer Lemon was losing leaves. They would turn partially yellow and fall off and it also would lose green leaves. I thought it was potted improperly and getting too much water. I think the water was an issue but only partially by causing the plant stress that allowed it to succumb to pests. After repotting it has one new branch with leaves and the rest had died back but I noticed an orange tree that was unaffected last year is suffering from the same leaf drop problem. I do notice little webs but we also have a lot of spiders here and I also have seen spiders on the plants so I wasn't sure it was mites. I have not seen any mites and am not sure exactly what to look for. I just discovered tonight that whatever it is has spread to my pomegranate. It is losing leaves, twig ends are dying back and also has tiny webs.
I sprayed them all down with some homemade insecticidal soap. Earlier in the spring, when I first suspected the mites, I sprayed with pyrethrins. That didn't seem to work so I released a bunch of ladybugs in the garden. Some ladybugs are still around but so is the problem.
My questions are 1) does this sound like spider mites? 2) If so and I treat with insecticidal soap, how often do I need to spray down the plants to prevent the mites from getting re-established?
Thanks in advance,
