Lime Tree Gets Scale

Question

Hi, I live in Western New York so I have to bring in my 4 foot tall lime tree every fall. And every time it gets scale, that I notice sometime in the winter. I spray with Aza Max weekly but it still comes back. I did recently scrape off about an inch or 2 of soil and then sprayed the soil. I have also wiped the leaves with alcohol. But the scale keeps coming back…..or maybe I’m not getting rid of it. HELP!!!! Please!!!! Where does this scale come from and is there anything else that I can do? What temperature can I put this tree outside and then spray it more intensely out side or use something else?

This article will give you some tips as to how to get the scale under control. It takes a while because of their hard shells, so you need to spray weekly for a month.
