I use a 1 eye cutting.... greatly reduce leaf size....
apply 0.1% IBA (Rooting hormone) stick in well drained soil. bottom heat 65-70F mist not usually needed....

where do you get that? and are there any other ways? thanks

by the way, if you want to use the water method, how do you do it? (lots of details please) thanks again

from my notes of over 50 years as a professional/comercial propagator.
the method described allows me to get the maximum new plants from a plant.....
I never use the water method as it is in-effecient for my purposes.

I root cuttings of golden pothos in water almost weekly... Yes I have them in every room of my home and so do all my family and friends now lol!

All I do is locate the longest stems on my mother/parent plant and cut about 12 in. from bottom-just above the little knots that become ariel roots (so that u include them at the base of your cutting-these will now turn into ur roots) Next I fill a vase with water..I use a pur water system on my tap. the vase should be no more than half filled because it will cause roots too high on the stem. I make sure to remove all leaves that would be under water with clean scissors. I simply place stems in the vase and then place it in indirect light.

This method works time and time again for me and never has problems with transitioning from the water to soil.. but I'm sorry I'm really no pro botanist so I'm sure there are more scientific ways to do this. Now, ur philodendron grows slower than my pothos but they are similar in other ways, so I hope this helps.

But nothing ventured, nothing gained-so give it a try!
Also, I beleive u can also just place the cuttings in moist soil and it will have the same effect.. something to ponder.

Good luck!
