[I bought some plumeria cuttings last September....., Do the cutting need to be kept cold and dry ? [/b][/quote]


hi there
my suggestion is to cut off any of the rot and keep trying. make sure you cut it well beyond where the rot stops.
with plumeria, they are full of latex (the white sappy stuff), and because of this are very prone to rot in the right conditions.
when you take a cutting (or cut off the rot bits) put it on a concrete patch somewhere about the garden to "dry out" for two weeks at least.
this allows the cut end to form a callous and therefore not allow rot in when you plant it.
good luck
and happy growing
