The Q&A Archives: Houseplant Breakage

Question: I have a large Diffenbachia (2.5ft.) whereI have accidently broken the stem. It is not completely severed from the roots, I would say the breakage is about 1 in. above the soil line in the pot.If I put tape around the severed part will it help to "knit" the stem back together? Is there a special kind of tape, or some other product I could use?

Answer: It might work. You might try wrapping some dampened spagnum moss or other fibrous material around it, matching up the broken ends as well as possible, and splinting it (maybe a ruler would do), then wrap in plastic wrap to help keep it moist, and tape into place using the wrap to avoid contacting the plant with the tape. You could also try rooting tip cuttings or laying stem cuttings horizontally to try to propagate new plants from the original. Take care not to get the sap in your mouth or eyes while you are working on the plant.
