opuntia looks healthy, you have no reason to panic, it is a hardy cactus.

Are you sure that this is a Trichocereus? Because there is such a diameter difference between the living top part and the dead bottom part I assumed it was a very elongated globular cactus and not a columnar cactus. Not saying you are wrong, but I still have my doubts about what this plant is. Noth...

Trichocereus are very hardy and can tolerate many beginner mistakes. Are you sure that this is a Trichocereus? Because there is such a diameter difference between the living top part and the dead bottom part I assumed it was a very elongated globular cactus and not a columnar cactus. Not saying you...

it looks wonderful, it is possible that it is a echinopsis hybrid, but I am not an expert. It looks wonderful.

it is very important what conditions you can provide to your cactus. Do you live in a house or an apartment? Do you have a balcony, terrace, yard or garden? We are practically at the same latitude, but in different parts of the world. NY has a colder climate, for me this year in the second half of J...

I graft seedlings of both Ariocarpus and Astrophytum onto Pereskiopsis stocks. Ariocarpus: 2 months after germination Astrophytum: 1 month after germination It is possible to graft younger seedlings but the above ages show the highest success rate of grafting. Earlier grating gives earlier flowerin...

you have to give the cactus the right conditions for it to grow normally. Obviously, your cactus does not grow in good conditions, it needs a lot of light in the vegetation and a rest in a cold place during the winter If you can give it such conditions, then you can save it, the lower part of the ca...

It depends on your vision and finger dexterity... over 5 years ago I was able to graft 1 month old aztekium and few days old lophophora. Some seedlings already sprout large so you can even graft a day or two after sprouting. NOW I feel clumsy attempting to mircograft and opt to not graft or wait a ...

How old must the seedlings be for grafting? So far I have had success with Lophophora seedlings that I grafted onto perioskopsis, but the seedlings were more than 3 months old. At the moment I have a lot of perioskopsis, and I have sown seeds of ariocarpus, turbinicarpus, lobivia and quite a few mor...

Thank's for identification. For me is important because of region from which cactus comes (soil and special demands).

Wooow very beautiful cacti! I'm mostly envious of your lophs and your ariocarpus. Btw your myrtillocactus lools like a stenocereus or polaskia chichepe Well, mytrillocactus is rescued before few years from garden center, for good price. Behaind big mytrillocactus are few small, which are purchased ...

For echinopsis, last winter temperatures drop below 0. One plant didn't survive.
Thanks for. Id pilosocereus.

Ariocarpus retusus
Very young.

This small beauty is lophophora williamsii from seed which I get from my plant. 9 months old.
