I have a portulacaria afra myself. It sounds like you got one at Loews, or somewhere similar, since there was gravel on top of the soil. removing it was a good move. I never understood why they glue rocks on top of the soil. I think this is to mimic the fact that most true bonsai are grown in a very granular soil. As far as portulacaria afra care goes, I keep mine in a southeastern facing window that gets direct sun. I had it in an eastern facing window for a while and it did poorly, I have assumed that this was due to lack of light. So be sure to give it as much light as possible. during warmer months if you can put it outside, then that will help it. those trees you see when you google portulacaria bonsai get alot more light than even mine does. that is why they grow so lush and compactly (the lush growth may also have to do with fertilizer). In terms of watering, portulacaria is a succulent, so it can withstand some drought, but it seems to be less drought tolerant than actual jade is. mine dropped its leaves once when I went too long without watering it. but you should let the top of the soil dry out before you water it. On to soil, typical bonsai soil is basically some sort of small gravel, maybe with woodchips or other large organic particles. However, I am an amateur and find that when I grow the easy indoor bonsai species such as portulacaria or ficus, they don't mind having regular potting soil. I usually buy the miracle grow potting soil from the store and mix it with perlite at about 1:1 ratio. my jade, and portulacaria, and ficus are all growing healthy and fine, even with reduced root balls. both crassulata (jade), and portulacaria are great plants for a beginners. This is because they grow in a very beautiful, bonsai-like fashion without even requiring much training. I have a 4 year old jade tree in a regular size pot that is incredibly impressive and looks like a miniature tree without ever having been pruned or trained. just make sure that you give it lots of sun and enough water. I am a beginner to bonsai when it comes to pruning and training, but my advice would be to worry about growing the plant normally first, and once you see that you can take care of it without training, then you can start experimenting with pruning and training. I don't know how much general plant experience you have, but it may be a good idea to try re-potting your portulacaria in a normal sized pot and try growing it For a year or two in that pot. Then maybe try pruning it down to bonsai size. it is a good idea when you start experimenting with training a bonsai to take a cutting of the plant to root a new baby plant, so that if you kill the parent plant you don't have to go out and buy another one. I do this all the time now. anyway, these are the things that I have found work best. Bonsai, in my experience, is not something you can just do. It takes years to get good at it. You will make mistakes in pruning, and you will kill plants, and you will have to wait months in order to overcome your mistakes. I did a bad wiring job on one of my trees two years ago and the scars are still visible . . . On the other hand, for most of the year all you need to do is water and occasionally fertilize your plants, you only end up doing the hard work once or twice a year depending on how much your plants grow. Good luck with your new plant and if you have any other questions let me know!

Hi & welcome to Gardenweb! What an adorable plant! Do you think it's Crassula ovata? ...so you've been "picking at it" and inadvertently caused it to look like that? If so, that would fall under the heading of bonsai techniques, but doubtful there's an established style of bonsai that this would fit. I'm sure you've been having a blast doing it though. I did this to a variegated ivy plant once. By the time I finally watered it to death, it had about 5 little hard woody stems, just a few inches tall, with at least 50 TINY leaves on each one. Wish I'd taken a pic of it. You could also generate a discussion about this on "cacti & succulents" forum, if you have an interest. Most of the jade-o-philes would be over there. And whoa - look at the fly trap plant!!

My black jade was covered in Mildew. It was planted on the east side of the house, got morning sun only for about 3 hours a day... Was right next to the house with no circulation... a combination of lack of sun and lack of air had the poor thing practically white... I would have bought another and planted it elsewhere, but I don't like the yellow stamens when it opens...

Never having used Oil-Dry leaves me at somewhat of a disadvantage, but I'll try anyway - your mix's suitability will ultimately show in the plants' health, but it sounds OK to me. I follow the chemistry somewhat, but I'd hate to go through that each time to get a suitable soil. You might be better off, ingredient-preparation-wise, to simplify that. A pic of the plant would help but if you've got some extra soil (even straight 'regular' potting soil) get it repotted, but don't water for a few days - if the plant's roots don't look viable you can still save the plant, but a picture would be the most helpful in diagnosing the condition.
