snipping old leaves to expose new growth

[RosieC]

I've had a very very limp leaf which has gone a sickly green/brown colour and it has hung on for six months.

I'm still leaving it because I figure the plant knows when it doesn't need it any more and will let go when it's ready. There is still some green in the leaf, it's not gone as brown as I've seen them in the past.

I would advise letting the plant decide when it's done with a leaf. If it comes away with a gentle tug then it's probably done with it, if not leave it.
