Can anyone please tell me what this Cacti is? Have had this one for several years and suddenly it had 3 babies. Two of the babies have grown fast and the third is still a tiny button. The thorns hurt and leave a sore place for days. Cannot handle plant now because it is so long. Last time I re potted it, it fell across my shoulder and boy did it hurt.
I have just found The Cacti and Succulent Forum and I'm loving it.
I don't know either but it looks like it's doing very well. If the plant ever gets truly out of control size-wise, you can always cut a piece off the end and use that to start a new plant. Just re-root it and presto, dangerous plant becomes manageable again (for a while).
I have this Euphorbia that is getting too big to handle. It will not fit inside this year. I'm trying to decide what to do with it. I have a lizard in the bottom of it. It looks so real that it has scared me a couple of times. I'll take a picture later.
It's a Ceroid, possibly a Armatocereus, Cereus, Pterocereus,
I'm looking through these albums of columnar cacti at this link: http://community.webshots.com/user/brcacti
Pay close attention to the spine arrangement and lengths. Also, the number and depth of the ribs when trying to find yours.
How about these? (right now these, pic 1 & 2 are on the patio.) I probably have 50 different and much loved plants in the sun room. Not sure how to mix soil for them. Love all I see, and also have about 100 named Semps. outside. LOL, that's how I got inside plants, didn't know the difference when I bought my 1st dozen.
Dumb as dirt about these things but love them anyway.
Regarding care... there's a living rock at the front left in the first picture. That one may not be compatible with the others in the container. I can't tell you the details because I don't grow those plants, but they are supposed to be a little picky about when they get water (or not). Maybe someone can offer an ID, that would help. The rest of the plants look like a good mix for a community pot. The ones that offset or branch (like the Mammillaria at front right in first picture) will eventually fill the pot to overflowing if they continue to grow happily, so you know. But that will sort itself out over time, as community pots usually do. That's part of the fun of setting one up. You never know where it's going to go.
As for the soil mix, everyone has their own preferences. So you'll have to find yours by experimenting. These days I use regular cactus mix straight out of the bag or (more often) with some pumice mixed in, up to about 50% of the total for certain plants with special needs. You can use regular potting soil if that's all you can find. Just cut it with more rock. Suitable substitutes for pumice include perlite and lava rock (scoria). Basically a light rock that holds air. Whatever you have available locally. The rock in that second picture looks about right (though maybe a little big for the size of the plants).
I like to sprinkle a thin layer of light rock on top of the soil (=top dressing) when plants are first installed in a pot. That seems to help with water retention, allowing me to water less often. It also buffers the soil against the harsh effects of the sun. And it's a way you can dress up a plant in its container.
Be aware that all things equal, shallow containers dry out faster than deep ones, small pots dry out faster than big ones, and unglazed clay pots dry out faster than other kinds. You can use those features to your advantage. For example, to avoid problems with rot-prone plants. But otherwise some types of pots tend to require more frequent attention and watering. This also tends to work itself out over time.
WOW! Thank you Baja for all the great info. gosh I do appreciate it and will print it to keep it handy.
I think I understand about the living rock because there were 3 at the beginning. I think two of them rotted..Oh goodness, I'll move the last one in the morning. Thanks big bunches.
