Growing a lemon tree indoors in a pot then putting it outside
I have an older lemon tree which produced over sixty blooms and now has many little green knobs but my leaves have brown tips and some are falling off. Please tell me what I'm doing wrong ? I don't want it to die on me . I want to put it outside in the spring . I have near my birds cockatials. Could they be cashing the problem? I also have a small Virigia pine next to it now that Xmas is over .Please I need help ..

If their urine or feces is getting into the container, then they are absolutely causing this. This will cause the burning tips from urea based nitrogen toxicity. I would recommend applying dolomitic lime to the soil to help drown out some of that nitrogen. It is good to apply this twice per year anyway, along with iron sulfate, and a citrus fertilizer.
