miltoniopsis
 

Hi all

first time poster long time lurker.

Can anyone help me?

My miltoniopsis herralexandrae finished flowering 3 months ago. it now has 3
new peusdobulbs growing in it. all about the size of a thumb. the problem is
that on 1 of the peusdobulbs a single leaf has started to go black. what
should I do? cut it off? leave it and see what happens?

any other suggestions would be helpful
