You might be able to save it, Susie: You will need rooting powder, available at most nurseries and supply stores. Trim the broken end by removing a couple inches of bark. Dampen the end (it’s good that the piece is in water!) and dip the end into the rooting powder, then make a hole in a container of moistened potting medium (or 1/2 portion peat, 1/4 portion perlite, and 1/4 portion sand), and plant it. Firm the “soil” around the plant. Put the entire thing into a clean plastic bag, secure it at the top and set it in an area that gets light but not direct sun. Look into the bag occasionally to be sure that mold or the like has not set it (if so, spray it with a fungicide). The rooting process will take three to four months or so. After a couple of months you can gently nudge the plant to see if it seems to have “grabbed” the soil (with roots!). Water as needed when you take a peek.
