Hi Mithander, Sorry, there's so much going on w/ this plant. Fungus gnats are generally indicators of too much watering. These plants are jungle cacti, not arid cacti, so they do need water w/ reasonable frequency & are designed to tolerate the extreme heat of the tropics. (They originally hail from Rio de Janeiro, Brazil which is where I grew up, so I know they have rainy season in January & that it gets VERY hot.) But that said, they need fast draining mix 'cause their roots can rot quite easily. Yes, flowering is a lot of work for the plant, but generally one withholds water for one month after flowering & then the plant slowly starts to come back. Usually mine start putting on new growth again in March or April & I resume a regular watering schedule. Maybe the soil you used had wetting agents in it? If you still have the package maybe read the list of ingredients. At any rate, soil that's too wet & then a a plant moved to a pot that's too big combine to make for conditions for rot. Also putting it into a cooler room combined w/ damp soil can also lead to serious rot & root rot (that's why you have fewer roots). These plants normally grow up in the crotches of trees w/very little mix & just whatever leaf debris & animal wastes happen to drop on them. Their natural habitat gets lots of rain, sometimes frequent rain (depending on the season). Sorry, but if a plant stays too wet, the last thing to do is water it more. Does the pot still have drainage holes? 'cause this is in part a bad drainage problem. I'd put it back into the smaller pot, into a mix of 1/2 African violet soil & half perlite or pumice. I'd smell the roots for rot & then sprinkle ordinary cinnamon (like you use for baking, actual to prevent rot) on the roots & then shake them off & pot up as above. I'd put the newly repotted plant into a position of bright, indirect light & then please leave the plant alone. These plants thrive w/ benign neglect & when healthy, a bit of fertilizer. They tend not to do well when fussed over. I realize you're trying to help the plant, but you're killing it w/ kindness & not resolving the basic problem which sounds to be bad mix, compounded by too much water & then maybe also cold, air conditioned air. While you wait for it to recover you can check out your other cuttings which you mentioned are growing well & also read lots of Christmas Cactus posts here at C&S. Good luck!

That is actually good, since now you have some experience in beheading :) As you can see, the plant survived accident and branched. Looking at existing mix, it may contain some bark - that is good (unless it is all sapwood). You could start making better mix by sifting existing mix (use kitchen sieve) to get rid of very small particles. Buy small bag of perlite, sift it too to get rid of dust, and mix sifted ingredients (larger particulates that stayed inside of sieve) about 50/50. That should give you quite good mix for succulents. (Small gravel, scoria, pumice, turface are all excellent to use for succulent potting media should you decide to grow more of them and put some effort in making your own, well-draining mixes.) Many of my succulents are overwintering in the basement that is dark, and I use lights that are on 14 hrs/day. Give your plant lot of light to grow more compact. If you use light, put it further away from a plant to begin with, moving closer every few days in order to avoid burn (using CFL, fluorescent or LED bulbs helps since they produce less heat, and likely brighter light).

They are reaching for more light. To keep these guys compact they need a good amount of sun. If these were mine I would start all over by cutting off the top. Let callous for a day or two and then replant. If you can they would do better outside. Before you put in sun or water make sure they have roots and introduce them to the sun slowly. They may burn if not ready. Lastly, take some leaves off to propagate. Goodluck:)

Sorry to disagree, but no, one shouldn't necessarily cut back on watering these Aloes in Winter (or maybe just cut it back a bit). Many Aloes can grow all winter long & since they bloom in Feb. I definitely wouldn't cut back watering in winter -- unless you're keeping them, pretty cool. In NYC, next to cold window over warm radiator, my Aloes stay in growth all winter.
