In the months I've had mine they haven't been difficult. But they're
still in the pots they shipped in, and I have them at work in an
air-conditioned office. They get watered a couple of times per week,
and I fed one plant an ant, but that's all I do for them. They seem
to take care of themselves, albeit slowly. They're planted in life
spaghnum, which unfortunately has a tendency to break down eventually,
which means I'll have to carefully repot them.
