Hi. I purchased a 3 year old Genoa #5 Dwarf Lemon Tree yesterday. I love it, it's a real cutie, and had three juicy ripe big lemons already on it (which I had to pluck off for transport on my scooter). The previous owner said something about it being due for repotting soon. In any case, I'd like to do so, so it'll grow bigger and make more lemons, so I stopped by home depot to pick up soil, perlite, peat moss. I have a few questions. Is there a better time to repot it or is now okay (I live in Los Angeles)? And, judging from the photo, would a 10 gallon container be a an appropriate size upgrade (right now it's in a 4.5 gallon bucket)? Also, should I have any concern about the tree being rootbound, and thus not a wise idea to transfer it? Lastly, the woman was giving it "partial sun". Practically the only place I have for it to exist is in full sun. Is full sun okay? Perhaps I should haul it indoors into "shade" every day for a few hours, to get it accustomed to more light? Thanks for any help!!
