Portulacaria afra 'bonsai'

joscience
15 years ago

One of my favorite local nurseries was having a sale on P. afra about a year ago. They propagate their own plants, I knew to look for mother plants instead of just freshly rooted branches. I searched through about 50 one gallon pots, and found a few gems.

I was content enough with these three to stage them right away, and I have another couple works in progress. I had a lot of fun playing with the lava rock. Something about it just "looks right" to me. It's also easy to smash break and form into your desired shapes. None of these have been pruned much. I'd gladly entertain any suggestions on what to prune...

This one looks better in real-life than in photos. Still, it is my least favorite of the three.


{{gwi:653133}}

This one will need the twine for at least another year or two. The roots still need to really fill the pot so the plant won't flop around and come out.

I really like this one. Probably the best composition of any of my staged plants.

    J -

    Those are great! I really like the way you have staged them. P. Afra is great bonsai material to play with - pretty predictable as far as pruning and subsequent budding behavior so you can really direct growth.

    My two cents is to give them as much sun as you can (e.g., their new growth looks a bit stretched), and to prune that new growth way back to get a tighter branching look. You may also want to start thinking about branch selection, primary branch, next one up, back branches etc.

    Do you use twine instead of wiring the plant into the pot? Interesting approach.

    Nice trees.

    Hi, why not add a little bit of organic compost to the mix, not necessarily as rich as you'd use for a deciduous tree or tropical house plant, just enough to hold a bit of water (unless you can afford akadama) in there, though mostly gravel is good. Your pot choice isn't the best - it's glazed, and overhangs inside which makes it difficult to repot when roots fill the space. You want something unglazed and with straight, or very minimally outward-leaning sides if anything, plus 1-2 good sized drain holes.

    Jose, As to your unid plant, it it one (I believe) of the many New World Crassulaceae hybrids - to me, it seems it has some Pachyphytum and Graptopetalum in it. Of the New World Crassulacae, Echeveria, Pachyphytum, Graptopetalum and Sedum are the more widely-seen species, and they almost all can be crossed with each other. Perhaps someone else can give you a definite ID.

    I guess I'm not good at waiting. I water mine when I repot and then whenever the soil starts getting pretty dry, as measured by sticking a wooden skewer in the soil for several minutes and then feeling how damp it is. That is the same process I use whether I repot or not, but I do let the soil get a little dryer than normal for a week or two after repot. ez

    Please don't get me wrong ladies, I really appreciate all the suggestions; they are all great leads and I'm learning a lot. Also, I'm not saying that it is a p. afra, I'm simply saying that, to me, that's what it looks like the most of all the suggestions. I know the importance of the leaf growth pattern but the shape of those leaves still look closer to the P Afra than anything else I've seen. Thank you for the picture of those flowers. They certainly could look like a berry type of flower LOL I will keep following your leads so please, bring on all the suggestions you can think of. I'll be researching more in-depth the tylecodons!

    I have one that is a wippy 4-5' tall.It was in sun until two years ago when a fence went up right in front dooming it too deep shade. Too late in the year to dig up?
    Jo,I like the second one best.I think the first two of yours only need tip pruning. The third one is a tough call.With so many vertical shoots, you have many options,from windswept to a mini forest cluster.

    Tom: Super nice plant. Really great ramification. I should have wet mine down for the pictures too, the red stems look awesome. Most of the etiolated growth is left from when it was growing at the nursery. They get full sun now, but due to my space limitations, they only sort of get it from one side. Since the shelf above them blocks some of the mid day sun, I try to rotate them every week or so, but often forget. You can see in the picture below how they are set up...

    I really need to do some major pruning, but I still have a hard time "seeing" the results before I do it. So of course that makes me nervous that I'll botch them. I suppose I should just be brave and dive in...

    Stan: We just posted at the exact same time! Jinx, you owe me a Coke!

    I don't think its too late to dig it up. Like Jades, I'm of the opinion that P. afra is pretty much bullet proof. As long as you cut back on water well in advance of digging it up, I think it will do just fine.

    I've always thought the third was suited for a windswept look, so that is probably what I'll try for. I'm having a hard time deciding which branch should be the leader though. It has sort of three equally dominant branches that all seem like viable candidates.

    I love those three guys in a row! Don't be afraid to prune them back, they respond well and grow fast, so it is easy to correct any errors.

    Here is my big guy. I posted pics of this one earlier in the summer when I got him as a 'shrub'. Bonsai pot next spring, I hope:

    Tom-- did you buy this as a shrub or did you grow it from a wee-lil thing? I'm always curious because in CO, you will rarely find a succulent this big (at least not Port-Afra). Mine were 3 inches tall when I got them-- they have trunks maybe a lil over half the size of yours.

    I can't wait to get mine into pots but they have a ways to go.

    Has anyone here used the trunk chop method on their Port-Afras? I chopped my biggest one this summer-- and I'm anxious to see it thrive again.

    Any updates on the Port-Afras? I don't have any pics of mine, but they are enjoying a great run of weather here in Colorado-- sunny and 70 every day-- very dry air is in place with only light winds.

    There isnt much new growth on any of my trees-- do these guys go into a full-on dormancy or just a slow down of growth?

    I have had mine pretty much stop growing completely during the darkest winter months, even under HID lights in temps of 60-70 day, 50s at night. So, I keep them pretty dry in the winter, but they do tolerate a bit of watering.

    Mine are still growing now, but with the impending cold weather that is forecast for here (upper 30s tonight!) I have brought mine in. All but a small cutting that I am experimenting with outside...

    I also sprayed them with Anti-stress 2000 (another experiment based on some information I read on this site) and there have been no adverse affects to the spraying. Now I would like to see if it makes them more cold tolerant, as it describe in the literature (hence the cutting experiment). I also did it as a precautionary (e.g., mites) spraying before bringing them in to close quarters will all my other plants.

    This might be one of those plants that looks nicer in a pot than in the ground where they become a green blob. This post keeps reminding me to dig up my floppy P.afra.
    Tom,that is a great looking plant to find in Maine. It must have been a rare plant nursery. Tom,what's that very nice plant to the right in your last photo?..I like the feathery leaves.

    Hi stanofh -

    That is Pithecellobium tortum, aka Brazilian Raintree (not succulent, sorry everybody):

    {{gwi:653140}}

    I live in Massachusetts - picked up the P. Afra in a bonsai nursery near me. The owner had just returned from FL with a batch of P. Afra. Found this one in the back...

  • birdsnblooms

    Tom..your bonsais are breath-taking. How much work is involved shaping, pruning, etc?
    Is the Brazillian Raintree tropical?

    I have a question you should be able to answer. I won a variegated Afra on Ebay..it hasn't arrived yet, so don't know its height. I would very much like to grow as a bonsai. Is there anything I should or shouldn't do to get it started? Keep in a small pot, for instance?

    Also, I have a Richardson Begonia in a bonsai pot. It's 3-4 yrs old. Although it's doing okay, it could look a whole, lot better. One problem may be it's in a north window.
    The foliage and stems are red, and it flowers, but not nearly as many as those seen online.
    If I were to prune, how much should be removed? Should pruning be done now or in spring? Thanks, Toni
    Again, your plants are beautiful..

  • TT, zone 5b MA

    Thanks for the nice words on the tree.

    I know it is off-topic, but the Raintree is a relatively easy to care for tree. Good light, drainage, and lots of food and they grow pretty fast. Just a little messy when they drop foliage indoors during the winter, as you can imagine.

    Here is a pic of it four years ago:

    {{gwi:653141}}

    Again, sorry about the off-topic stuff...

    Hi Toni -

    Thanks.

    Not seeing the P. Afra and being able to see trunk girth, size, etc. it is hard to give specific advice.

    In general, though, if you want it to thicken up before you stage it for bonsai, it would be best to get it healty and growing more freely than plunking it straight away into a bonsai pot. In fact, I often keep my plants growing in stock pots for varying periods of time before I bonsai them. That allows it to get some root growth to start in the stock pot - but I also start lightly pruning it with a general design in mind (unless you need to thicken up some branches, in which case you may want to let them grow more freely). When you prune, it is pretty easy to anticipate the branch direction from the prune - you will get buds at the base of the remaining leaves at the point where you pruned.

    Then, when you are ready to stage as bonsai, you will likely need to root prune to get it to fit in the pot. So, do the typical succulent routine for this - prune and let it callous over a bit before you water.

    Sorry, I don't have any direct experience with that type of begonia.

    If you want some real inspiration for P. Afra as bonsai, Google "Jim Smith Portulacaria Afra" and check the images that you find. You can also find some good care information here:

    Tom...Do you know if bonsai art can be done with C. (Jade) ovata? Standard Jade.
    I started a thread here tonight, but so far no replies.
    I've seen Jade bonsais sold at Home Depot, but don't know if they used a different Crassula species. They look similar to ovata.

    BTW, I checked out the website you posted..It's quite informative..didn't have time to read through the whole site, but will do after deciding what to do with my Jade..I'd like to get it started..Thanks, Toni

  • TT, zone 5b MA

    Hi Toni -

    Jade can most definitely be 'bonsai-ed' - you may just have to quell your enthusiasm a bit for now. The best time for drastic root and branch pruning is spring.

    See this link on that website for more information - good luck!

    To tide you over until spring, why don't you make a Jade Mame? Take a small cutting cutting with the growth point still in tact. Next, place the cutting in/on a piece of very porous rock, lava rock is ideal. (If you really want to allow for maximum growth potential, drill some small holes for the roots to eventually grow out of and into some soil you place below.) Now just put it in a warm, bright spot, and wait a few months. The cutting will root out into the pores of the rock, attaching itself and making an instant, tiny staged plant. You can get pretty creative with shaping or finding the rock. I know it isn't quite as satisfying as pruning and staging a full size bonsai, but now is actually a pretty good time for this little project.

    {{gwi:653142}}
    This is mine after I think about six months. It is totally attached and putting on new growth. I took this photo a few months ago, so when I get home, I'll take another one, showing the new growth.

    Love the rock jade - is that what they call "root IN a rock style"?

    A few notes for those who try it:
    *Warmth always helps!
    *You've got to be patient after you finish placing the cutting. Moving it around or checking to see if there are roots will damage the tiny new roots, and make it take way longer.
    *The rocks obviously don't provide much in the way of macronutrients, but they do a surprisingly good job with all the micronutrients (lava rock in particular). That means very slow, but healthy growth, especially if you keep them in the sun.
    *Watering will have to be closely monitored to figure out how your particular rock responds.
    *Carbide-tipped masonry drills are awesome for playing with rocks, pots, and all sorts of other hard things. Buy a few of the cheapies at Home-Depot and use slow speeds and ample water.
    *For city folk, check out landscape supply yards for rocks.

    Same view as before, taken today.


    {{gwi:653145}}
    New leaf pair and the stem is putting on a little size too.


    {{gwi:653146}}
    Right now, it gets full early morning sun, and shade in the afternoon. Although it has a nice red blush, tt might be getting the tiniest bit etiolated, so come spring, it will get moved out to full sun.
