Re: Christmas Cactus


My Christmas cactus did something similar 2 summers ago.  Just fell apart.
I took the sections and tucked them into the soil in a new pot.  More than
half are growing just fine (blooming or preparing to bloom now), the others
are still green but lie on the dirt - flat, just as you describe.  I have no
idea what is wrong with the poor thing, and no idea why half of the starts
look great and the rest I should probably give up on.  They share pots and
soil, go figure...

I'm pretty sure they live a good long time - I have a friend who has a one
that's at least 3 feet by 3 feet, and she's had it maybe 25 years.  It is
gorgeous when it's blooming.
