Today I will be propagating a large Dieffenbachia I took on from a friend moving overseas. I watched a bunch of you tube videos to ensure I do it properly as I would like to get the maximum yield out of it.

In one of the videos when you cut off the leafy top they said to leave it to dry out for 24hrs before putting it in water? Other videos said you could stick it straight into the soil?

I know they are quite hardy plants and seem to grown no matter what you do but I would be devastated if I lost the top growth as it is currently the only leafy part of this 10ft tall plant.

Thanks in advance for any advice!

Some plants root better if the cuttings are allowed to dry over night. I do not know if this is true for diefenbachia. It helps with Geraniums/Pelargoniums.

I think you are better off propagating the cutting in water or damp soil right away. Smaller, shorter cuttings with fewer than 6 leaves propagate more readily than older, longer stem cuttings.

Great advice guys. Glad I waited, tonight's the night! I too feel it should go into the water straight away. The trunk on this thing is thicker than my wrist so I bet it's a very thirsty plant! I've named it Newman after the previous owners and a little bit of a take on Seinfeld! lol

Thanks!!!!

It seems plants that are juicy inside benefit from drying to lessen the chance of rotting. I have started cuttings with diefs both ways and both ways worked well. I think that Will's advice is far more relevant to your success than hardening off is. They are an easy plant to root, but easier when cutting is young growth.
Good luck.

Thanks for posting the photo. It certainly is long overdue for pruning. You can probably insert the top cutting right in the same pot and let it root there. Cut back the remaining lower stem to a height of about 6 inches so new growth will start there and grow upward.

You may also be able to root the bare middle section.
