Could have been overwatered...why did you remove perlite?

Most succulents have 'hard time' to overwinter indoors. Many of us use supplemental lighting to help them. Succulents should not be watered too often, less in colder temps. Watering thoroughly when needed is much better that watering often in small sips.

Well draining soil helps a lot; if you can get some grit & perlite added, it will be good for many plants. If you have only perlite, min. 1/2 of the mix is often recommended.

Put some more mix into the pot, the plant would look much better (IMHO :) and there will be better air circulation around it (that would apply to other plants, not only succulents).

This kalanchoe grows taller and older stems become woody. New growth would be quite lanky in less light - they don't need strongest sun, but good light is important. I keep all of my succulents outdoors as soon as it is warm enough.

You could cut off the etiolated new branches and re-root them to make new plants. Original plant will keep growing for years (I have one for 4 yrs now), but needs to be 'tidied up' at times.

They grow extremely easy from leaves - if the leave is just touching the mix, many new plantlets will start growing from the wavy edge.

I didn't use perlite with the second repotting because it seemed like it was getting too dry too fast after I used perlite the first time. I would go to check on it and it would be bone dry, and with barely touching it to check the soil, a leaf or two would fall off. It was very disconcerting! None of these problems happened before I repotted it with the perlite, only after. That's not to say that the soil I'm using doesn't have any perlite--it does, I just didn't add any more like I usually do for succulents.

Ah, I wish I had an outdoor space...I live in an apartment. No yard, not even a balcony or a patio to call my own. Alas. I've been thinking about buying a grow light, but they're just so expensive! Maybe next season, I dunno.

I've been wanting to learn how to propagate plants...maybe this is a good opportunity for an experiment! What kind of medium should I place the cutting in?

Just wanted to chime in on cheap grow lights, you can get LED bulbs that screw into a regular lamp for $10 on amazon. I got a couple last year as a gift, they worked very well over the winter months in a floor lamp fixture.

@Kim, do you think the LEDs will be strong enough to grow herbs? That's what I'm aiming to do, and while I had some basil that did ok last year, my mint this year is already looking kind of sad.

@Rina, it's quite possible transplant shock was a factor, but I would have expected the plant to recover from a transplant shock eventually...the plant never seemed to recover for months on end, which was why I repotted it again, changing the soil, as soon as spring arrived. I do think that at the first repotting I should have kept it in a 3" pot instead of moving it up to a 4" pot. Moving from plastic to terra cotta also made things drier, in addition to the change from the relatively heavy, moisture-retentive mix it came in to my lighter mix amended with perlite. I guess it was a combination of factors, and then the dark, long Wisconsin winter that made things turn out this way. Maybe I should just start fresh with a new plant...it might fun to experiment with starting a cutting, but I imagine you have better luck with that when your original plant is healthy and vigorous, which mine is not. Might still be worth a try though.

From here it looks like the saucer is attached to that pot (handsome pot it may be, but could be a problem). Does that pot have any hole in the bottom? That's really a must.

It might be, I am not sure. It was strong enough to burn leaves on a Hoya about 10" away.

@lmontestella, the saucer is attached to the pot, but it does indeed have a drainage hole and it drains freely when I water it. After watering I carefully tip it a few times and make sure the saucer is dry and empty before I put it back in its usual spot. I don't let it sit around with a saucer full of water by any means.

Good to hear, thanks for answering about it, sounds like you've got that well in hand, tho' I'd agree it still needs the perlite, lots of it.

Original plant didn't look so hot either :)...here it is just before chopping:
(see date here & on photo of clippings)

I have a K. blossfeldiana myself, got 2 last year as tiny plants in 1" pots and stuck them in a 4" terracotta. One is still weakly blooming, but both are making much smaller leaves than they did before. Kind of strange, and not sure why it does that. Once the temps get a little warmer I will bring it outside.

I am not sure, but maybe trimming off the flower stalks and pruning could make it grow larger leaves?

Maybe, I might try that.

It's making smaller leaves now bc the warehouse that grows them pumps them with lots of fertilizers and stuff. Im in the FL Keys and I never have any small leaves unless yhat part the plant has gotten knocked off or got a kink on the stem. I have an 8×3' harden on each side of our front door. One side is nothing but difft types of Kalanchos and they get Big and bloom all at once for the hummingbirds to come in spring. But remember that everything you pull a leaf you have a potential for a whole new new plant or more. Its crazy o just stuck the leaf on top of an empty bottle and wait. Its cool how they make a whole plant from between the ridges. My neighbor brought me 3 leaves from Hawaii about 15 years ago. I'm now in engaged with them, but its OK, I give lots away and the key Deer don't eat it! Win for me. Good luck, I know its been over 4 years but I still thought I'd answer your question. I hope 2020 goes away fast, its Dec 11....2021 can't come fast enough ✌💚🍄🎅🎄 Happy Holidays everyone

@Quispy, Wow, that sounds amazing! I love hummingbirds. I have definitely given up on kalanchoes but I live in a new apartment now with more space, and I just recently set up a grow light. So, perhaps I will experiment with some plants that need more light tban I had at the old place. I now have a balcomy garden where I grow herbs, and hummingbirds come drink lavender nectar all summer, and we get so many happy bees too. It is lovely. 😍
