Warmer winter for some mammillarias?

Post by conolady »

Can anybody tell me which mammillarias, in their experience, require a slightly warmer winter temperature? I'm thinking c. 7C or 8C perhaps. Guelzowiana comes to mind, but I'm sure there are others it might be wise to be kind to. I've a few small poshies and would rather not lose them!
First it was orchids, then, since c.2001, cacti and succulents. I'm into South African plants, mainly conos, lithops and haworthias, with a few cacti, especially 'posh' mamms, turbs and other smalls. Now it’s stapeliads as well...

I haven't found M. guelziowana to be too fussy, mine are kept with the general collection at no less than 5c and as long as they are bone dry I have had no problems. Off the top of my head, M. nivosa and M. beneckei/balsasoides would probably like a bit of extra warmth as they can be rather touchy.

Thanks, Diane. I haven't got those yet so I'm still OK heatwise. Some folks have mentioned
guelzowiana and possibly haudeana to me, but it's interesting you find the former at least no problem.

I agree with Diane about M. guelzowiana, I've had mine for years and just keep it at 5 c minimum, no problems.

M. guelzowiana will happily go below freezing and does fine at 5C. For warmer ones, look to the Caribbean species. M. columbiana is one that I keep warm, although it is actually only found in South America. Possibly they don't even need to be that warm.
