How to start another rhododendron from an existing plant?
Question:
Answers:
try what is called layering. place a brick or heavy rock on a bottom branch and leave there for 2-3 months. when you check it then. there will be roots on the branch. chop off and plant else where. this works better with a little compost around also.
After the plant has finished blooming, find a healthy, growing branch. Cut about a foot off, but do not get into the older, woody growth. Remove any flower buds (they will just sap energy from the cutting). Dip the cut end into rooting hormone powder (you should be able to get a small envelope for a couple of dollars at most nurseries). Push the cut end into a one-gallon pot full of moist potting soil, and firm the soil around the stem. Keep the soil moist; give it bright light, but not direct sunlight. Within a few months, you should have a new plant, ready to be planted outdoors next spring.
