I have a lime tree (dwarf) that previously had a bug problem (see thread "white bugs on my lime tree"). It recovered from this very well, but now that my tree is back outside (Ohio) the leaves have turned from a healthy green to a sickly looking yellow color. Any suggestions on why this is occuring or how to fix it? Limes are still growing, etc. Is it a lack of acidity in the soil (it's in a pot)? If so how do I go about fixing this? Thank you for your help, Andy
