I’m 6 months in with a small Dwarf Improved Meyer Lemon living outside is San Francisco. My yard gets lots of fog but also lots of warm sun; the tree is planted in the sunniest spot. The trouble is that I have a lot of yellow, dropping leaves. I’m fertilizing, watering about 2x a week. I believe I may have a drainage issue or root issue - or is this something else? I don’t see any bugs, mold, eggs etc and it is prolific with fruit… but the fruit stays small and green. Maybe I need to thin the fruit and pull it out of the pot to check drainage? I’d love other opinions before I go through that, thanks!
