Re: rooting Pterocactus cuttings

They root OK. I have around 12 including most of the species, but like all tuberous rooted plants when rooting they appear to just sit there for a while not making much top growth until a tuber forms below the soil. Also, you probably know that unlike most cacti the flowers are terminal on the stems...

Re: Variegated. But how? Which method we can take advantaged of?

More or less like breeding roses I guess you just keep crossing the ones you like best, raising those seedlings and throw disappointing ones away. Obviously, you will have more luck doing it on a large scale than an amateur with a dozen or so plants to start with. Thats how the Japanese breed their ...

Re: The Cal-Mag of my dreams?

In the UK I tend to use Tomorite tomato feed most of the year = NPK 4-3-8 since the ratio is the same as 8-6-16 if doubled up since its just dependent on the strength of dilution of the liquid in water, therefore similar to Steve's 7-7-7 plus extra potash? I will also often use a normal fertiliser w...

Re: Plant watering alarm/reminder gadget

I am old enough to remember before he bought the company! LOL Look forward to seeing your results. I suppose you could use a sensor in each sized pot, but pots in different parts of a greenhouse could dry at different rates. As I have at a guestimate around 900-1000 plants one in each pot would be e...

Re: Carnigea gigantea?

They say the first hundred years are the worst for a Saguaro, after that they tend to get a move on! :lol: However, a British Cactophile grew one bedded in and flowered it not long after this newspaper report was published in just over 40 years in Britain's dull climate. Main problem is growing such...

Re: Plant watering alarm/reminder gadget

The problem with most watering devices I have come across is they don't work too well with small pots since the soil is not deep enough. Also, with gritty dry type cactus and succulent soils not in intimate contact with the length of the probe. With sensors permanently in a pot you would need one fo...

Re: Copiapoa cinerea seeds

For certain rarer species on seed lists you have to order immediately the list comes out since they will be in demand. Many choice seeds are in short supply but put on the list to both attract buyers and also sell the commoner species. Some dealers in the past, before email and PayPal, used to have ...

Re: Coryphantha ID

In case beginners are confused, as Tom says the name of the type form retains the same name for all subspecific epithets = C. robustispina ssp. robustispina v. robustispina f. robustispina, but we normally shorten it to just those infraspecific levels needed to identify it at the time = C. robustisp...

You only need to Google for them Nachtkrabb. See:- https://www.bing.com/images/search?q=Astrophytum+nudum&form=HDRSC2&first=1&tsc=ImageHoverTitle Most cacti are nude in the botanical sense since they have smooth epidermises, it is usually only applied to those like Astrophytum's where th...

Re: BCSS

The main problem for printed publications these days, along with enhanced printing costs, is postage and shipping. The American Journal over the years has gradually reduced from the 12 original journals per year to 6 over most of its life, but now four larger issues due to this reason. Particularly ...

Re: BCSS

Not sure it is up to date and all links are still live, but Cactus Mall carries a list of most of the world's Cactus & Succulent Societies or Clubs. Some are simply branches of the country's main society, but some independent clubs.
