I wish there was something I could do to get rid of the #%$! spider mite on my key lime tree. I give a thorough blasting shower once a week. I've sprayed it numerous times with soap and twice with BioNeem in the past three years. This morning when it was getting its regular Saturday shower...WEBS! There's no other plants in the house with spider mite that I can tell...I've even checked them over with my magnifying glass just to make sure I'm not missing something...most of them also get a shower at least once a month just to stay clean and healthy looking.
I grew this tree from seed and its now about 4 feet tall, very healthy and full, except for the persistent spider mites...#%$!!!!
