How Can I Save My Hanging Impatiens Plant?
Impatiens are really easy to grow from cuttings, so I would suggest that you cut off the healthy looking ends of the stems and and start some new plants, which will be identical to the parent plant since they are literally clones. You can put the cuttings into water or into soil and then keep the soil moist. I don’t even use rooting hormone on impatiens cuttings because they do fine without it, but my climate (northern California) is milder than yours and I grow my impatiens outside. After you take the cuttings, cut off all the dead growth and cut back the entire plant to healthy green growth – 3 or 4 inches is enough. Then repot the plant using fresh potting soil. You can use the same pot, pruning the rootball a bit if you need to. Impatiens are hardy little guys, and I have had great success in renewing my potted ones in this manner. Good luck!
