I've read of honey being used as a rooting dip for cuttings and pups of some tuberous plants. Also as a foliar spray when diluted with water. Does anyone have experience with this? How does it work?

Honey is a powerful antiseptic so I guess it would work similar to cinnamon, in protecting the cutting while it waits to root. I've never tried it but I think I might!

Agreed. But I would wonder if the high sugar content might suck things (by osmosis) out of the plant tissue, especially water. Dunno, and certainly worth a try.

I had a friend who spilled a pot of boiling water on his bare foot and was severely burned. His body is very sensitive to chemicals and at the time, he didn't have health insurance, and didn't go to the doctor. I am not sure where he got the idea, but he spread honey all over his foot. It healed remarkably fast, he said.

Honey also has anti-fungal properties which would help fight off fungal diseases. To get the most benefits from using honey as a rooting hormone it should be pure or raw honey not the filtered, processed honey sold in the supermarkets. You should also make sure to keep the cuttings damp so that there is enough water present to keep the honey from crystallizing which would clog the plants vascular system and cause it to die.

I've not used honey for rooting anything since I have pretty good luck rooting stuff just poking cuttings in some soil. I researched the question and posted the most common information I found about it.

This would be a good use for that honey left in a jar after you've got all you can out of the jar. I've read you can use the honey straight or diluted in water.
