Anthurium leaves suddenly turning brown
I have an anthurium that was flourishing until about a month ago, with red flowers and good leaves. Now, all of a sudden, all the leaves are turning brown and the blooms have gone away. I have some pictures on Picasa:
I water them twice a week and they are on regular potting soil and they get reasonable sunlight which is not direct, since there is a curtain liner in front. None of that has changed for the last one year.
So, what gives? Any ideas what is going on?
Appreciate any feedback.
