Hello my 15 year old Dracaena got over watered by my children and the stem seems to be rotted. Now, the plant drooped and I was able to cut the top half, which seems to be hanging on for dear life. I have put these clippings in water before and they die without giving root. I placed the top half in dirt and is the last stem of the plant and don't want it to die. So I am wondering can these plants survive if I dip it directly into the dirt or do I have to dip it into a root generator? It is a small plant as I kept it about 2 feet high but have had it for 15 years and would like to save it, any help is greatly appreciated. Thank you.
