I have started my Philodendron & pothos in glasses of water.
while my book says to put rooting hormone on the ends of cuttings & pop them in soil, I pop mine in a glass of water & they root like crazy.
I also did that with my bamboo. Now that too says use soil--but I guess there is more than one way to skin a cat..
BTW: I have lots of cuttings of the palm I would gladly share. They are about 1-1/2 tall these days. A guy Rod works with gave them to me---and really I have no place to put them were I to pot them up.
My MIL grew sweet potatoes
in water also. She would add some of her African violet food to that water so they would root & grow greenery. That makes a very pretty plant as well.
