From what i can see, I love your backyard. It looks so peaceful, and that purple plant is gorgeous.

I used a product called "Bang" to clear up a spidermite problem a while back and the application said to use 3 parts water to 1 part Bang. WAY 2 STRONG!! Within about 12 hours every leaf was turing discolored and the stems were starting to go limp. This is a 3 month old mother mind you. I rushed her into the bathtub and sprayed her down as best i could, but the damage was done. Since then i tried the product again and found that a 20 part water to 1 part Bang works alot better as opposed to there recommended dosage. IMHO, i would use any of those sprays at 1/10 the dosage and work up from there just to be sure.
