Could be a fungus like Vladimir said, could also be an insect egg or just dirt on a bit of fluff. However, I'm more concerned with how dusty the leaves are. I may just be dust or it could be the beginnings of a spider mite infestation. It's a good idea to wash off the leaves from time to time, like maybe every 4-6 weeks. Take them outside and hose them off, or if that's not possible, put them in the shower and shower them off with cool water. Then let them drain well and put them back where they were. It helps prevent spider mites as they're attracted to dusty plants. And your plants love the rinsing off!

Am guessing on the last two, the 1st some kind of Rhipsalis, the 2nd some kind of Epiphyte. I'd suggest the pots for the last 2 are rather too big (tho' I see you got this nice, chunky mix which is likely to be fast draining). Pls. excuse me for not wanting to repeat all the tips for Holiday Cacti (both Thanksgiving & Xmas). Pls. search around here for the posts which include a link to "Holiday Cacti", the excellent link which is so often provided here. They explain care & culture better than I could. As to the Jades above, other than feeling like your BIL should not have watered in new cuttings, I'd leave the rest of that to others as well. Just pls. do a search on Jades or Crassula ovata in the meantime, as there are mountains of info. on this posted right here. My short answer on the Jades is since he watered them in, I would NOT water them AT ALL until I saw new growth, but perhaps others will feel differently. Good luck w/ them all!

Hi Nancy, Thank you! :) I just got it a few weeks ago and have already seen one leaf unfold. I too am a little puzzled about the name and color. I have searched and like you have not found one with the beautiful blush. Like you said, it could be for the young. But yours is a good size. I know alot of succulents have different colors determined by the amount of sun they get. I got it from a very reliable nursury, so am confident the name is right. It does seem alot like yours. hopefully someone who knows more about this plant will come along. :) For now, that's the name of mine. :)

Cheryl Yes, while jades can handle some soil as a part of mix, gritty/gravely mix is good - great drainage, air exchange. I think pruning depends on your 'vision' of finished plant. I personally like them potted single, with thick trunk. Others may have different likes. I like bonsai styles, but don't have enough knowledge... I would prune all of the branches - make them short; most likely I would cut off the thick one and pot it as separate plant. It is good time to do it. Yes to acclimatizing, especially if they were indoors for a while. Also if re-potting and pruning - I would keep them in some dapple shade/filtered sun to begin with (not necessary to bring them in), and keep putting into more sun every 2/few days (I don't know where you are). Here is photo of one with 'extra' branch, before: (there are many good threads on pruning on this forum - search for 'chopping jades')and after: If you like to start new thread, after opening Cacti& Succulent forum, there is large 'box' on top; put title of your thread in top column (where it sayz Example title), and continue with text & photos below. I wouldn't start new one on this subject - it's already 'running' and would be duplication. You could put zone/general location next to your name, it will eliminate questions "where are you located" :) Rina
