I broke a branch off of my poinsettia and put it in water in an attempt to start a whole new plant. The branch seems to be growing in the water but it won't grow roots. Is there a way for this branch to become a whole new plant?

It can be somewhat difficult to try and root broken branches. However, if you want to try to propagate the broken stem, use only an inch or two of bare (green) stem with a couple small leaves, or tip cuttings, since these root much easier than the old, woody branches. Stick the cutting into a pot filled with damp potting mix and seal this inside a clear plastic bag. This will help retain moisture similar to a mini greenhouse. Place it in an area receiving bright, indirect light. In about 4-6 weeks, the cutting should be rooted and can be taken from the bag.
