Eduardo,

Fausto lives in the Northern Hemisphere and Brazil is in the Southern
Hemisphere.
Your Arisaema may be confused about what season it is. I've had that
problem
growing tubers from New Zealand and Australia here in North Carolina.

Normally they should grow for a couple of months at least, but if the
tuber seems ok
and not significantly smaller than when planted, all is probably ok.

Your temperature is not bad. 4C is 39.2F and Arisaema will consider that
a proper winter
if it stays in the vicinity of 40F for 2 months or so. We don't actually
know how cool it
must be for proper growth to resume in the next season. Mu guess is
around 50F, but it
is only a guess. We do know that 40F for at least a month, preferably 2
months works
well.

You can get extra seasons of growth per year by placing the tubers in a
frig. at 40F
for 2 months and then replanting them. The moisture conditions are
critical so
look up "forcing" in the Arisaema-L archives to see how to handle it.

Forcing is one way to get their timeclock adjusted to Brazil.
