I am growing a lemon tree in a pot in my living room. It was previously in a greenhouse ahd produced fruit. It is producing healthy leaves now but no flowers or fruit. Somtimes I see little black coloured “twigs” that break off it. Can you advise?
A lemon tree needs the warmth of a greenhouse to flower and fruit but must have as much sunshine and heat as possible and the light indoors is much less. A bright porch or conservatory would be good.
