You have a jade, aka, crassula ovata. It is in desparate need of light. Was this where it was when you moved in? If so, do you have a balcony on which you could slowly acclamate it when the outside temps are above 55 or so consistently. If you just moved it to this spot and it is better-lit than where it was, these could be sunburn marks. Typically sunburn marks are more uniform in shape, though. It should have about 1/5 the amount of space it has between the leaves. It almost looks like it is supposed to be a Crosby's Compact which should have all the leaves very close together with proper lighting. Jade grows spindly when it isn't getting enough light. I would take it out of the plastic pot and repot it in a clay pot. Buy one that is shorter. THey are sold as azalea pots. Your soil should be very free draining. When I mix mine, I use one part pine bark fines or soil conditioner, one part grit (decomposing granite), one part high fired clay granules (turface, aquatic soil), and one part small pea gravel. When you water it, water should run almost right through it. If you use peat based soils, they will compact and stay too wet, thus strangling the plant due to lack of oxygen. Even the soils that say they are for Cacti and Succulents are too peaty. You could also try coir inplace of the pine bark fines or in addition to them in place of peat. Almost anything you would use for a bonsai would be okay for a jade since they are very free draining. They don't need a lot of fertilizer. Use something low in nitrogen. I use Schultz Cactus Fertilizer mixed for every watering, but I only give it to them every other watering during their growing season. It is warm where I live until Oct or Nov, which is usually when I stop feeding and slow down watering to once a month until it warms up again in spring. We were warming up in March and then had a frigid spell over Easter holiday. I've gone back and forth with my plants, but having a mild spring has been nice for a change. I hope this helps, and don't hesitate to ask more questions. Do searches on this forum about Jades, and you'll get more than you ever wanted to know about jades. They are, without a doubt, my favorite. I have about 10 different plants, 10 starts from cuttings and two that are bonsaied.

HMMM, well, I am almost disappointed. Of course, the variety you named, I believe makes it a parent of a true Christmas Cactus. I thought for sure it was one from pictures and descriptions I had seen. Totally not upright in its growth, etc. Oh well, none the less, I do think it has been around for some time and it is pretty big. Plus it did bloom at Christmas through the first couple weeks of January. So, I am not going to tell it any different!!! I am going to give the re-potting a whirl this weekend and will keep my fingers crossed that I do not break much. Thanks for the details on what to do. Lastly, since it does hang down so much, and it looks pretty silly with it staked up like I have done. Do you use any of those florist type wire rings, or something like that for support? (Like a very small tomato cage that would follow the edge of the pot?) Thanks to everyone for the help and the ideas of how to treat my very pretty cactus. I can't wait to try my hand at getting it to bloom this Christmas. Hazel

I have no idea, but you could ask in this thread for the Thanksgiving Cactus? https://www.houzz.com/discussions/insecticide-pesticide-insights-dsvw-vd~3742440 If not, then please post your results there. =)

Okay, there's a lot you could change here. First of all, keep in mind that your plant is a grafted cactus (called a 'Moon Cactus'), and they don't necessarily last that long, though they might survive for a couple years. Next, succulents don't like terrariums and such. Also, fish bowls are for fish, not plants. So, if you really want to do what is best for the plant, it would be best to unpot it and buy a nice terracotta pot. A lot of people run into problems with soil, so I will give you an easy mix that you can make yourself. it is pretty easy- 60% perlite and 40% any cactus and succulent soil. You should be able to find perlite at pretty much any garden center or Home Depot/Lowe's. And finally, plenty of people don't realize how much sun succulents want. They want a lot. Like, A LOT a lot :) So pretty much the more the merrier. BUT, keep in mind that even if you do all this stuff, the cactus may not last long, so it may not actually be worth it to go through all this trouble. I don't know. But you can certainly try ;)
