I used to have 2 Dracaena Janet Craig too, at that time not familiar with its culture, not even knowing what type of Dracaena it was. Just took it for granted that it is alive indoors or in a shaded setting. When we moved, I made the mistake of planting it in a full sun area, and come rainy winter time left it outdoors too. They are tough plants indeed, and I am left with one little bare cutting, I am not giving up yet since, I still see some green on the stem and I have seen it try to produce a little offset on the little branch it has. I have lobbed off all the totally wilted and dried up parts, and keeping fingers crossed that it will somehow come back, am planning to move it to a regular soil set-up, it has been sitting on hydroton rocks and some little water for awhile.
My 2 Dracaena Janet Craig before we moved:
And how she is right now..down to one little cutting..still alive I think
So give her some time...it should bounce back eventually. I see you have a variegated Schefflera in your collection there. Dracaena has similar needs like your Schefflera, though Dracaena's are much happier in shady areas. I remember having some aphids and scale issues with my Schefflera & cycad outdoors and I used a mixture of water, with a few drops of dishwashing liquid and some tabasco sauce..somehow it worked in the removal of the buggers.
