Mike--
Question,,,You SAY YOU WILL HAVE YOUR CALADIUM BULBS UNDER LIGHTS ALL WINTER??? (oops..capitals...)
Do you dig them up and then put them in trays under lights??
I dug all mine up and put them in a shallow box with a lot of dried, crunched up, leaves in bottom and on top.
I plan to keep them this way all winter in my Shop. Cool--about 58*
My 3 Clivia pots are also in the Shop on my work table right under a 4' fluorescent shop light. That is where they live--and have actually bloomed.
My cut back 3 brugs are down there--as will be a hibiscus I had last summer.
All the rest of any available space is full of houseplants and X-mas cactus and too many Spider Plants. My 2 Epis--and lots of cuttings of all kinds of things. Glad I live alone--I would not want to hear bitching about too many plants. Welll--YES! There are too many..... Gita
