Bottle brush plants
I have looked at pruning bottle brush plants online and it says cut to node below tip if stem. What is a node and should I cut the wobbly bits off after the flower has died? What is meant by the tip of the stem?
The node on a stem is where the leaves attach.
The tip of the stem is just that, the outer most point of a stem.
