I have a Jade plant
. I have had it for three years. It has never had spots on it but the leaves began to fall off and it didn't grow much. I planted it in a bigger pot and it is growing
nicely. I read one time that Jade plants
are only suppose to be watered at a certain time. There is a time when they are dormant and I can't remember if that is the time to water or not. I know they are a very picky plant
. Good luck. Here's a website for you to check out where I read the info. http://hgic.clemson.edu
