Re: Did I get sold a dud? Cacti with no root system

Hello Hero878, I do work here in the U.S.A. for the Department of Agriculture and am still tasked with CITES issues. CITES stands for the Convention on International Trade in Endangerd Species of Wild Fauna and Flora. The import requirements for cacti - which almost all do fall into that category - ...

Re: Hana's cacti

Hello Frank, you seem to be doing a lot of cactus repotting each year. What is the method you use, in order to keep possible problems for the re-potted plants at a minimum? I have always been a bit afraid to take a plant out of the soil or pot, because it is almost impossible to totally prevent tear...

Re: My flowering Cacti 2021

Hello Cactus Friends, today I was finally able to take some photos of one of my Ariocarpus fissuratus plants with a wide-open flower. Now two of the four plants in that pot have bloomed. The others will most likely follow suit. If one of the plants should produce a blossom of a different color hue o...

Re: Black/brown skin fungus, initially firm before rotting

Hello Download, I just noticed, that nobody did respond to your post. It may already be too late and your cactus has "kicked the bucket" due to the rot is was experiencing. Your first image does show what looks like two slices of a small cactus. The piece on the left is not discolored and ...

Re: My flowering Cacti 2021

Hello Cactus Friends, now wth the month of September being here, the last group of my cacti is beginning to bloom. While I still do have a few flowers being produced by my Turbinicarpus plants - during the last three days Turbinicarpus gielsdorfianus and T. schmiedickeanus ssp. klinkerianus flowered...

Re: My flowering Cacti 2021

Hello Cactus Friends, after a long pause I can show a few more digital images of flowering cacti. The rains we did have not too long ago, breathed new life into the plants, which in some cases responded by flowering again. Others would have bloomed anyway. During the last 10 days Astrophytum asteria...

Re: Rot from top - Discocactus

Hello abhikjha, I noticed, that nobody did respond to your question. Well, I believe, that is because the situation with your cactus looks rather bleak. First off, rooting hormone most likely will not do much good on top of the plant. It should be applied to the base of it to hasten root growth. The...

Re: scale disease on torch cactus

Hello splosh, I just noticed, that nobody did respond to your cactus problem. In the topic headline you use the term "scale disease". There is indeed a disease, which is commonly called a "scab", but your cactus plant stems are not infected by it. I believe, that the problem is n...

Re: My flowering Cacti 2021

Hello Cactus Friends, @ Keith: Echinocactus horizonthalonius does flower repeatedly, if the weather conditions are right, i.e. after rains. Perhaps you will get some precipitation really soon. We are here in our "monsoon season" and I have not had to water my cacti for several weeks now. M...

Re: Some fungal Diseases

Hello 7george and greenknight, controlling nematodes is not an easy thing indeed. While these small worms do look very fragile - and in a way they are - they do seem to be rather successful to remain in the soil, because their eggs, cysts or defense mechanisms will allow them to survive. In addition...

Re: Welcome Craig Fry!

Hello Craig, thank you very much for your quick response to my questions. I had no idea, that it is very difficult to root members of the genus Discocactus. I am rooting my offsets or pups using our local arroyo coarse sand/fine gravel mix and at least the Echinocereus, Echinopsis, Tephrocactus, Opu...

Re: My flowering Cacti 2021

Hello Cactus Friends, during the last three days two genera of cacti did flower. First off, both of my larger Thelocactus bicolor were in bloom. One is of the more common variety schottii and the other a light-thorned version of the variety bolaensis or flavidispinus. Here are three images of these ...

Re: Potting pups

Hello gillinger, I have successfully rooted cuttings of Peniocereus greggii and also pups by placing them in coarse sand. The cuttings were kept in a semi-shaded area near my pecan nut tree and received watering by my irrigation system three times a week. I always made sure, that the cut or base of ...

Re: Cactus peeling / spitting - don't know what to do

Hello riwremo, I have had a few splits of some of my cactus stems, but they were vertical and not horizonthal as is the case shown on the photos. So I would diagnose these cuts as having been caused by a human or animal, i.e. mechanical injury. They do look like something sharp like a knife or a sha...

Re: Welcome Craig Fry!

Hello Craig, I am sorry to see that your large Discocactus horstii succumbed to root rot. I also so thank you for making the best of the unfortunate situation and to show us the inside of a cephalium. It does indeed contain living tissue. One question I wanted to ask you: I do see a number of pups g...
