Hi Steve,
The temperature is not a problem, installing a portable heater would be unwise. Note, that a Carissa is a plant which is in the Southern part of South-Africa, where temps can drop to around 32F. My Carissa is standing in an East facing window, without a central heater underneat. Temperatures vary between 70 during de day to 60 at night. As it is next to the window, temps maybe even dropping till 50 F.
I water the tree on Saturdays totaly (till it comes out of the drainage holes) and spray it. On tuesday I only spray it. So I get it through the winter. When nighttemps outside dont drop under 50F the tree goes outside in full sun, there it will be watered when needed, in summertime this will be every day. This kind of bush doesnt require a lot of water, you can tell, cause of the thick leaves, they hold water and a better equiped against evaporation through the leaves.
Hows the drainage of your soil? Does the water flows freely through? I think the roots are heaving a problem, for some reason. This effects the leaves.
Hope this'll help again,
Cheers Wessel
