How can you tell when a plant is dormant?
Except for the obvious reason like dropping leaves or dried out vines, how do you know if a plant is dormant? Slow growing cacti would be nearly impossible to see if it is dormant or not. As I understand some grow in the winter, some are dormant in the summer, some are confused and follow the seasons from the hemisphere they are from (how that is possible is beyond me:)
So, is there a way to tell when a cactus or succulent is dormant? Does reduced watering around this time of year automatically send them into dormancy?
