I have found this plant to be a very difficult grower. I have noticed that
it likes cool temperatures. My plant after having been dormant for the past
six monthes finally started growing again and is putting out new leaves and
stolons. I grow mine in a thin layer of live sphagnum with peat underneath.
The problem that I have not yet solved is that peat and sphagnum get too wet
and break down. It (at least mine) does not like it wet and it would be
advisable to keep it wet to the touch. If your plant goes dormant, which is
almost inevitable during the summer, keep it dryer than normal. Otherwise it
will rot. If you keep it cool, with temps allowing to drop to around 10-13
deg C. at night you should be fine.
I wrote an article for CPN some time ago which I put onto my web page which
can be accessed with any browser. Here is the address
