Spraying of a lemon tree
I just planned a dwarf Meyer Lemon. I can see clearly that a systemic would be bad to use, but my question if you don't eat the peel or the zest, the lemon would still be safe to eat when sprayed, and I am sure they spray commercial lemons. I am worried about scale and spider mite, I see both of them from time to time in my garden. You have to keep on the scale because once it forms adults brown spots you can not get rid of it in a large tree. You have to cut off everything with the adult scales and sometimes it's the entire tree. I had a abutilon that was there when we bought the house and I never got rid of the scales. I was reading here, about scale and spider mite. So, I had better start to worry now.
