I read somewhere that Weeping Willow branches don't need rooting hormone. In fact, if you take a branch and boil it in some water, that will itself make rooting hormone for other plants to grow roots.
I don't plan on planting one in the yard but I think it is nifty that a branch from this tree will cause other plants to root out. I am taking a gardening course too. Of course not having that, I use honey as a rooting hormone when I need one.

I know you can make your own rooting hormone dip with willow branches. But can you make it with other rigorous rooting plants such as mulberry bushes by soaking their branches or roots in water for a while? What about kudzu?

I prefer to use honey as a rooting hormone, and it helps to keep rot from setting in also.
Robyn, do you mix the honey with water first, or use it undiluted? Thanks, Nica
I dip the tip of my cuttings into honey. This works as well as any purchased rooting hormone. jjs w palm fla.
bsvgs - dip the ends of the cuttings in honey (no water)
Honey are sometimes adulterated. How do I identify quality honey
you dip the cutting into the honey after you make the cut....you then need to put the cutting into a growing medium such as Rockwood cubes or a product I use called root riot......they are sponge like blocks that hold moisture and support the cutting while it roots....the roots actually grow right through the blocks and you can plant them directly in soil.
For the make rooting powder :
1) Buy a can of root hormones. This hormone is called indole butyric acid. This is a powder composition.
2) Buy a pack of baby powder from the pharmacy!
3) Mix baby powder and hormone in 0.2, 0.4, 0.6, 0.8 and 1% ratios in separate containers.
4) Dissolve the rooting hormone with ethanol. If you fail, use Koh.
5) Mix the mixture in baby powder to create a paste.
6) Powder the mortar after drying.
Now enjoy the root powder.
7) Use 0.2% and 0.4% for soft cuttings.
8) Use 0.6% and 0.8% for half-timber cuttings.
9) Use 1% concentration for rough cuttings.
Honey is a great natural alternative to chemical rooting based rooting hormones. This is a page about using honey to root cuttings.
