Karrie, are you sure the "sponginess" is related to the worm attack? They
sound two different things to me, those probably being larvae of some butterfly
or other flying object, and this looking like a stroke of something (cold wind?
bad drainage? damage to the roots? excess of fertilizer?). Are the leaves
falling as well? Are they becoming chlorotic/ brown/ yellowing at the tip/
stay green but folding down?
However if I were you I would cut well below the spongy or necrotic
areas, disinfect lightly (a very mild copper mix perhaps) and review growing
conditions, specially drainage. Consider also the possibility of build up of
salts from over-fertilizing. It could be a fungus attack of course, but before
taking any measure try to change some of the growing conditions and see
what happens.
Good
luck,
Alessandra

To all you fellow Brugmansia
lovers:
My three Brugmansias (in
pots) are the only high-maintenance plants that I have, and they are my
babies. I fertilize them heavily and they reward me with tons of blooms
almost year-round. My problem is this: my double white is being eaten by
small green larvae, which I have been hand-picking. However, associated
with this attack seems to be a sponginess and die-back of terminal
branchlets. Has the worm infestation brought some disease that sounds
familiar to someone? Does anyone have a possible treatment for this
condition? This plant has always been very healthy and bloomed profusely
from November through January and March through May in its
south-facing covered-deck aspect. I was hoping it was a transient
problem, but I am beginning to worry that I may lose the plant before I get to
make my Christmas pine- and- white trumpet flower arrangements!
Help!
