I have a small lemon tree I am growing in a pot in our bright office (I have no idea what kind, it was given to me with a tiny label just saying "lemon"!)
It's still a very young plant, but has three fruits on it. One is now about 4-5cm in size and as just turned a very bright yellow all over, should I pick this now and will it be safe to eat? I'm a little unsure whether it's ripe; it's quite small, it's also a brighter yellow than a typical lemon and is very round, not the usual rugby-ball type shape!
All help is very much appreciated, I've never tried growing anything like this before, but it's a much loved plant!
