Hello,
my ZZ plant has multiple of these small stems with only two leaves, can I use these the propagate by stem cutting? Or do I need to use one of the bigger stems?

Well, I can't say for certain about this specific question, but in general I've propogated zz plants by tiny cuttings successfully.

You can see my little zz cuttings behind the blooming aloe. They've all rooted successfully. I planted them about 2 months ago.

Interesting! Thanks @CrazedHoosier , i didnt think they would root. Ive always pulled the little bulbs with the 2leaf stems.

I was surprised when I pulled one of my cuttings and saw roots growing! Roots appeared about a month after putting them in the soil. Now they're so well rooted in I can't pull them out without hurting them!

I'll try with mine as well then, thank you!

Cora, you could try rooting a stem of your ZZ Plant (Zamioculcas zamiifolia) in water. I once unintentionally broke off a couple of stems of a ZZ plant (one stem had only two leaves) but I stuck the cut stems in a jar of water along with pothos and philodendron cuttings and placed the jar on an open shelf in my kitchen. I had no idea if the ZZ stems would root and it took quite a long time before anything happened. I changed the water every couple of weeks and the Pothos and Philo rooted quickly but it seemed to take quite a few months before I noticed little bulbous rhizomes and roots on the ZZ cuttings!

@Plantladylin So your stems did not have a bulb until after you had it in water???

Correct, they were cut stems that I stuck in a small jar of water and the bulbous rhizomes were produced after a few months sitting in the water. I was quite surprised!

Oh wow, I think I'll try putting one in water and one in soil, maybe I'll be lucky as well and something grows, thank you!

Keep us posted on how they do!

I will!

A small update:
I ended up putting 4 in soil and 1 water. 3 of the 4 in soil have already grown rhizomes (even one that was only a leaf cutting!) which are still very small, but success for now! The fourth one was actually the one I had the most hopes for, I think its getting there but I'm not sure. The one in water seems to be growing tiny roots now? No rhizome so far but I'll keep you guys updated!

My ZZ-Xpiremnt. Started in Oct 19'

So.... This is where i am so far..... You guys think its ready to go in the soil? Will the roots develope once in soil?
