Re: Keeping Cacti Gnarly and Stunted

I was curious if any of you Cactus growers like to keep your Cacti looking more wild and rugged, and if you have any tips on how to do so. I think climate and manner of growing will influence this a lot. A grower in a warm, sunnier climate, with a short winter, high sunshine hours and very good gro...

Re: Anybody grown Curio (Senecio) from seed?

I've heard they are easy from seed, but I failed to get and germination with Senecio kleinia.
Maybe it needs to be fresh?
If you've got a lot of seed, why not sow some asap using a "normal" method and see what happens. And report back here!

Re: Pilosocereus Azureus Fungal Issue

I really appreciate all the timely responses! We had a few nights dip down below freezing for an hour or so and a few of those nights it was wet as well, must have been when it was damaged. BryanO, thanks for your response, too. The specific temp / weather pattern you describe is interesting to kno...

Re: Grandfather's Cactus

Trichocereus spachianus or a related species or hybrid looks good to me.

Re: Pilosocereus Azureus Fungal Issue

I had them outside and we’ve had some temperature swings and rainfall that they had to endure. Not especially useful for us to know unless you tell us where you live, your climate etc. The planet is a big and diverse place. Pilosocereus need warm winters, in the UK >10deg C or similar is often ment...

Re: Dormancy temperature genus by genus

All brazilians and southern mexicans need above 12-15C. Oreocereus isn't frost hardy IMHO, there're no frosts in Bolivia. Lots of Brazilians and southern Mexicans will certainly prefer warm temps. Some parts of Brazil do get frosts, but these are very much the exception. Oreocereus celsianus / trol...

Re: Rooting opuntia robusta huge pad

However I noticed it is more oval in shape and not perfectly round as its other names would suggest, a wheel/silver dollar cactus. Any tips on how I can make sure the new growth will be round and why this was oval? The pads are often more round than many other opuntias, but don't expect pads to be ...

Re: Whats wrong with this Lophophora pup?

I've had these orange patches on seedling before, like spread out over several, and a small winged bug hanging around there, sitting on the seedlings. No idea if this really was connected, but saw it more than once, and only on those specific seedlings....Either the bug is doing something there, or...

Re: Are these Pilosocereus Calcisaxicolus?

I don't know, but I'm not sure it's a valid name anyway. It doesn't appear on this list, even as a synonym:

Re: Did my Bolivian torch cacti get too cold? What else could be wrong?

Where are you, and where where they sent from? It looks to me like they may have got frozen solid in transit, in which case I'd expect they are dead.
Are they squashy to the touch, or firm?

I agree, they also look like they have root mealy bugs.

Re: Dormancy temperature genus by genus

I’d say only the Melocactus would need the higher temp. Oreocereus trollii would be happy with heavy frost if dry, it’s hardier than most Mamms.

Re: Eriosyce laui

I grew them from seed last year, I've still got one on its own roots, nearly 1 year old, still with seedling treatment (16 hours LED light, plus warm and fairly damp). i grafted 2 other seedlings (plus 1 which failed), I thought I'd wait until I get plenty of my own seed before doing extensive own-r...

Re: Is this really a Golden Barrel

It looks like a younger plants that has been grown rather more quickly than yours, in favourable nursery conditions. So it has fewer ribs than your older, harder grown plants and has larger wooly areoles because it's been growing until very recently. I guess that after a year under your care, it wil...

Re: Why aren’t epiphytic cacti more popular?

Given that they are a fairly small subset of all cacti, they don't seem that unpopular. And given that most of them aren't especially small, they don't lend themselves to people with limited space keeping many of them, unlike, say Mammillarias or Turbinicarpus. I'd love space for Selenicerei and wal...
