    My plant in the cranberry pot is dog tail are you saying the pot is to big thats why its not rooting? I didn't think a 6 inch pot was to big for 6 plant cuttings?

    What kind of soil is it potted in? That could be contributing to the lack of apparent growth. Did you allow the cuttings to callus over before planting?

    I use cactus soil I was told just to put the cuttings in soil and they would root.

    This may be a helpful read, both in terms of how it grows naturally and how to care for one in your home.

    Yes i have seen large dogtail cactus plants they are beautiful when there in full bloom but they need to be taken care of not letting them grow out of control. I guess what you have been trying to tell me is i need to put my cuttings in a smaller pot for them to root is that right?

    OK i appreciate all your comments but i don't think were getting anywhere i only wanted to know how long it takes for the cuttings to root and what the name of the other cactus i showed you was, so far i haven't got an answer. so i will say thank you for your time and i will do a little more research to get my question answered. again thank you.

    Compare your 2nd pic with Aeonium. Better pics would help.

    Your cactus might be Acanthocereus tetragonus? When you want to root a cactus, they must be kept shaded for a couple months, so they can concentrate their energy on making new roots, and not on trying to remain hydrated with roots they don't have. The cacti are planted rather deep in the pot which makes them recieve less sunlight. It's possible that species of cactus requires more sun then it's getting. Acanthocereus tetragonus is always found growing in sand, in the wild. This might be the cultivar 'Fairy Castle'.

    I was confused and thought you wanted the potted cati cuttings ID'd. I didn't take much notice of the 2 other pictures because they were so dark that an accurate is impossible, but Aeonium looks right for species. Most photos of Dog Tail Cactus show them spilling over in pots, so seeing cuttings growing vertically straight is misleading. Acanthocereus tetragonus, and DTC Deamia testudo look very similar, but Dog Tail Cactus Deamia testudo has much longer glochids,(thorns). It appears like your cuttings have the longer glochids of Deamia testudo. Acanthocereus tetragonus can become decumbent and spill over in pots too, but it appears more rigid than Deamia testudo when it spills.


    Deamia testudo. Also goes by the names Selenicereus testudo and Strophocactus testudo. Deamia testudo grows on trees and needs water more often than other cacti, but the potting mix should still dry out between waterings. I recommend putting it outdoors for the warm season, because it loves full sun.


    Acanthocereus tetragonus

    when the cuttings were giving to me i cut off the thorns they were brown where the mother plant is in a very hot window and they were sun burnt didn't think it would hurt the cuttings.

    Cutting the spines won't hurt them. They look like they have some long hair-like spines showing up against the background of the dark pot, but it's blurry to the point that I could be mistaken? That's why I included the pics. The glochids, the raised growths that the spines come out of, look larger than Strophocactus testudo, and more like Acanthocereus tetragonus. The link says Strophocactus testudo has shorter spines when it gets adaquate heat and humidity, but even at their shortest length, they are still much longer than the spines of Acanthocereus tetragonus. A photo showing the spines much clearer would help. They both have to be cared for differently. And best to do it when the spines have grown back to their original length.

    The raised area where the spines grow out of are the areoles, not the glochids.

    Glochids are the small, barbed hairs found on the areoles of the sub-family Opuntioideae - the prickly pear and jumping cholla family. These may have spines as well as glochids.

    I should have brushed up with a cactus anatomy illustration before I started. Thanks for the correction! I've probably spent many hours pulling prickly pear glochids out of my hands with tweezers. Weeds always seem to congregate right in the middle of them. I've ripped them out and pitched them twice because of the agony, and now Im growing them again. I must be a glutton for punishment?
