This is one of the original "cement" cacti I first posted about last year, and again a few months ago regarding black spots. I still don't know what it is :8 but the spots have not spread and something exciting is happening! The plant is about 11" tall, and in the last 2 weeks it has sprouted a marble-sized growth! Is it a tumor? A survival function by running away from the yet to be diagnosed black circles? Or is it a baby? Either way, I need to know what to do about it, lol! Other plant is unidentified, (help!). I picked it up for 50 cents due to some softness ~ probably rot ~ at the base of one of the ... ummm... bodies(?) there are four bases all this is growing from, and it is in a 4" pot.
The third picture I have one exactley like that!!!!!,I got it for a present, they said it had no name tag :( but I kept it and repotted it and it has gotten bigger mine has always ben softness I got it on march 12 and mine is neraly 1 year old. I would also like to know the name of this plant ;) Heres mine:
I can't help you with IDs, but that growth on your "cement" cactus, bcgirl, is both a baby and a new branch. Once it gets bigger, say the size of a ping-pong ball, you can gently cut it off the mother plant (using a sharp, sterilized knife) set it out to dry and callous over, then plant it into fresh, sterile cactus soil. Then you'll have two cacti, one of which won't have the black spots (hopefully). On the other hand, you can leave it on the mother and watch it develop into a branch.
Yeah good fun when you know it's Euphorbia but not sure which.... at least they do all seem to have their own characteristics and generally you'll be able to narrow it right down..... unlike some cacti where the more you look into names it actually expands the possibilities.
I think we found our Plant!!!!!!! ;) Thanks mandarin + joclyn http://www.cactusmuseum.com/photo.asp?PlantID=9&Genus=
Yes, that's the one. Note that "monstrose" is the English word, the scientific (Latin) epithet is "monstruosus". It should be easy to propagate by cuttings in the usual way (make the wound as small as possible, let dry for a least a few weeks, put in dry compost in a small pot, do not water for a few weeks more, and then sparingly until the roots have developed). I do not grow Cereus, but I once rooted a C. peruvianus and the roots developed fast, I could water it normally after just 3-4 months (at room temperature). That is fast for a cactus (where I live).
Holy Moly, They (yours and mine, Blake) look like Twins!!! what are the lighting / temp requirements for this one, do you know??
I was encouraged to move these 3 cacti from the planter as they apparently have different watering requirements. They are the original "cement cacti". I was was about to go about repotting when the baby sprouted. Now my partner thinks that it wouldn't be growing babies if it wasn't happy where it it is. But... He also thinks I don't water enough. I am unsure. If I wanted to move it anyway, would it be wise to do so in its present condition? how long should I wait? What do you all think? pics of them THEN: in July, in 2" pots, in the "cement" , and NOW: in planter
The "baby" should not really be there, the growing point has probably been damaged and it is now producing an offset to compensate for that. It should not be affected if you move the plant. What disturbs me is that it is growing now, when the plant should be resting (dry and cool). How much water do they get? Maybe you are watering too much ...
I have a water meter, and aware that watering is the big cacti killer, I water maybe once every three weeks, if not longer. Due to the black spots and fear of spreading in case it was fungi, I had not been watering at all, preparing for a transplant to segregate it from the others in the planter. That is what I was preparing to do when I noticed the marble - baby. Trying to give the required light, I use a 4 foot ballast, and tried to follow advice regarding keeping these bulbs within 4-6 inches of the plant. Obviously, this Cleistocactus (?) is the tallest cacti I have, and so the top is 5 inches from the ballast. The lights are cool - heatwise However, the new growth is coming from the side where some heat may be reflected from the wall for a different plant i have. The wall is 3 feet from my cacti. WHERE is the baby supposed to be growing from?
They do not really need much light right now, it is even possible to store them in darkness in winter if they are cool and dry. I store mine in isolated windowsill, refrigerators and other places with a suitable temperature that I can find. If they are warm and the soil is wet they will continue to grow, and then they need a lot of light. It is difficult to produce the necessary light levels with fluorescent tubes, the usual way is to use high-pressure gas discharge lamps (sodium lamps etc.), but they are hot, heavy and consume a lot of electric power.
Really? Is it possible that this cacti is mis - ID'd? Or are all cacti babies born from the base regardless of species?? How very odd. The baby is growing very well, too. I'll take a pic for you all. Maybe it will generate more ideas ;)
For that species, it should be occuring at the base, but some others propagate from stems (see Jumping Cholla for a good eg of that) - however, as we've discussed, yours appears to have had some kind of stress-related stem-baby experience.
