How much do you have to move? If you are getting a uhaul you could use a propane heater to heat the space. They just hook on the top of a propane tank. To me I think it's safer than electric ceramic heaters or a kerosene heater.
no its just 4 plants all 1/2 foot. i was thinkin just heat the car up nice and warn and when actually move them i might put a plastik bag over them but not sure please need more info!!!
ive moved small plants in a suitcase its only an hour away and you got heaters in your car i wouldnt be too worried id be more worried about them falling over and snapping
