Kalanchoe Propagation Experiment (Spagnum Moss vs. Peat/Perlite vs. Water)

- In my last video, I hard-pruned my kalanchoe and ended up with a bunch of cuttings I wanted to root. I decided to take this opportunity to see which method was the best for rooting this plant. I used the methods I most commonly use which are straight spagnum moss with humidity bag, 50/50 peat/perlite, and straight ZeroWater filtered water. All cuttings were then placed in bright indirect light next to each other by a NW facing window for 2 weeks.
I checked the roots in the water cup (clear cup) after 1 week but decided to let the experiment run a little longer. Here are my results after 2 weeks:
Water: Produced a few long skinny "water roots" that will need more adjusting once transplanted to soil.
S. Moss: Produced many short stocky roots along the entire stem.
Peat Moss/Perlite mixture: Produced minimal short roots similar in structure to the sphagnum moss but less of them.
Thinking back, I should have used a humidity bag for all of them to equalize the experiment. I will add that the next time I do this experiment. Sorry guys!
Conclusion: Even though the water produced the longest roots, I think I prefer the sphagnum with the humidity bag as I rather have healthy roots with less risk of transplant shock when I pot it up in soil. That being said, if I were to pot into leca, I would definitely go with the water method as there doesn't appear to need an adjustment period.
Thanks for watching my little experiment guys! Please feel free to drop me a comment below with any feedback. Have a wonderful holiday!

I love that you said "for this particular plant"
Haha, I do find that certain plants vary in their preferences, so wanted to make sure that I put the disclaimer in to not mislead anyone. :) Hope you enjoyed the video!
excellent comparison! i've been trying to find a comparison of sphagnum by itself vs a perlite + xxx mix and this video really helps outline two of the best options. I'll use water only for "easy" probs now and moss / perlite + xxx for anything else. Thank you for putting in the effort to do a follow up.
Great experiment! Thank you for posting 🙂🌱
Great live demo thank you!,,
Thanks for sharing
Thank you for your video. 🙏❤️
Do you allow the stems to callous before placing them in the medium you want to use?
Water works awesome if you are constantly checking, however, i find that if you have too many plants, 😂 i just stick in cococoir or cocopeat, dont water at all (just randomly mist or after a week do one good rain water) and forget about them for a while.. they do great! *keyword forget* 😂
Hi. Could you please tell which type of Kalancho is this?
Also very interesting experiment. Thanks!
@@AndrewRichmond-y1s thanks a lot!
Thank you for sharing. Any updates?
Would you use the bag with the water also?
Can you remember which transferred to a growing pot the best?
Hi! How long did you wait from the moment you cut them to the moment you put them in the soil/water/spagnum?
question for ya !
- i currently live in an apartment with not very good lighting & i noticed my kalanchoe is getting long with less leaves & ive had this plant for years now & was curious on if you recommend i should get a grow light & if so what kind? i really love this plant it's a from a funeral from someone i care about & would do anything to help it stay alive . i just need some tips !
I'm sorry for your loss! I absolutely do find that plants "stretch" and grow thinner/taller when light is inadequate. I would recommend a grow light to supplement, but as the top fills out and gets heavy, I would watch to make sure that the original thinner stems can continue to support the heavy growth and not topple over! You can also simply try snipping and propagating a brand new plant as a back-up. This will allow you to grow a thicker stem from the base.
Also don't be afraid to prune for thicker leaves!
What if my cuttings don’t have air roots? Will they still grow?
Yepp! As long as it has a node, the roots should come in rather quickly!
Which species of kalanchoe is this?
Is there a reason you pull the leaf off from the middle? My instinct is always to use my nail to pinch it off. Thanks!
Hi! So I pull the leaf from the middle in order to keep a bit of the stem/node tissue intact at the end of the leaf. I've found that it increases the chances of the leaf growing roots if there is that half moon at the end where it was attached to the stem. If you don't care about propagating that single leaf, then you can certainly pinch it and let the nub left on the stem die on its own.
@@plantingparadise1546 always learning every day! So cool! Thank you
Do you not need to let the cutting callous over in the part that you removed the leaves before planting in the mediums you used? I always thought that needed to be done as well? Mine look just like yours right now so I'm about to prune and propagate but want to make sure I'm doing it right! Thanks for the video!
So generally, I don't callus my fresh cuts. I know that many recommend it, but honestly, for my Kalanchoe, I just immediately pop it in water. They root so easily I don't even usually use rooting hormone or anything like that. For my monsteras, philos, syngoniums, I will pack the cut with dry rooting hormone and "let that dry" for a few minutes but then pop it right into water and I have not had any issues. I find rot more of an issue if the cutting is older and pre-callused. Good luck!
@@plantingparadise1546 thanks so much for your reply. So even the cuttings that you put in soil you don't let callous over?
Sorry I meant your peat/perlite mix (not soil) Thanks
And is the peat/perlite mix moistened?
@@natalieaaby7002 I didn't. The significant perlite concentration tends to keep the soil well aerated enough that I have not had a problem! The plant also has a natural immune system that if healthy, does a good job keeping rot at bay, in my experience.
Did you keep the S-Moss moist those ten days? And when are they ready to be re-planted from the S-moss to peat-pearlite? Thx
Hi Clyda, I kept everything lightly damp the entire time. I usually will go to my permanent medium once I see branching of secondary or tertiary roots which has worked well for me! However, after this experiment, I threw everything into soil and everything grew well.
Nicely done... but it's pronounced "kal an ko e", not "kal an klo e". No "l" in the last syllable
That's what I get for learning words from reading rather than speaking. Lol. Thanks!
I was pronouncing it kalan-cho. Turns out that's the British pronunciation, so I wasn't compleeeetely wrong. 😂This plant confuses me in many ways.
