Yes cuttings are easy enough to root. Some folks just put them in a glass of water.

Thanks for your response, mrimpatiens. I haven't been back to this forum for some time. They are doing very well outside now and I will root cuttings later this summer.

No don't put them in water. The roots that come in water are not strong roots. First take your cutting--cut a 4 inch peice from the growing tip, cutting just below a leaf joint. All roots come from a leaf joint. Moisten a good mix like pro-mix and fill your pots. With your finger or something poke a hole in the soil. Dip your cutting in rooting hormone--I use stim-root no. 1. Put your cutting in the hole and cover it in. Keep the soil moist but not sopping. In about 2 or 3 weeks you will see new growth and that means your cutting is making roots, but don't remove it from the pot for a month or 2.

Be aware that all impatiens are prone to spider mite. This tiny unseen bug can kill impatiens and it hatches out every 3 to 5 days. It hates cold and wet and loves dry and heat so they thrive indoors. That is the main reason I no longer take cuttings to overwinter them. If you do overwinter some have some insecticidal soap on hand and use it often
