|  4 months??? geeez.
i started re-watering last week. heaps of stuff is starting to pump and grow.
over winter i water everything (incl. mexican minis) occasionally very lightly to just moisten the top cm or so of soil. stops the roots dying back quite so bad. also seems to keep the plants in good cond while they are sleeping. and i mist spray regularly to keep spider mites down and i'm sure it has some benefit to the plant (if only to remove dust to they can photosynthesize better lol!).
i grow alot of stuff that is fairly forgiving of over-watering. eg melos (slightly moist constantly) and gymnos ( my new obsessession.. come from a similar climate to our own and don't mind cold or moist at all) and 1x uebelmannia pectinifera v. multicostata (don't grow that like a cactus!). water it regularly all year round, just lighter in winter. its growing in pure scoria so its kinda hard to overdo it. seems to really hate dry spells. |

| speaking of the Gymnos:
the most alarming thing is i only just started collecting them
group shots:
^^a pair of G.horstii and G.denudatum.(often confused but the latter is a much nicer plant IMO)
^crested (or cresting) G.baldianum.
^Gymno cardenasianum...best spination of all and one of the slowest growing of all cacti.
^mated pair of gymno ragonesei
... and their offspring in my prop. (8 months? old) perfect replicas of parents now. these lil bubs arent all of em either.
^rather large G. quehlianum
any more names for the ones in the group shot can be glady provided.  |

| Yeah I water most of my cacti (or let the rain do it), just mainly the ones in the pics that don't get watered, the penis plants have been water a few times over winter. There is mainly Astros, Arios, Turbinis, Lophs and some Copiapoas and Eriosyce on that shelf and they haven't had water.
Yeah I agree about the roots dying back etc. though they are looking pretty healthy really and I still get, often heavy condensation in my hothouse at times so the epidermis of the cacti get moist, I can only assume that the droplets would trickle down into the pot?
My main interest is Mexicans cacti and so amny of them are very unforgiving of overwatering, I have lost a few Astros before so am careful, too careful. Plus I get absolutely no sun in hte winter months so am not prepared to push my luck with the rarer more expensive cacti, when I move I will be much more prepared to water year round as there will be sun in the winter, I will make sure of that.
Actually most of my Trichos, Echinopsis, Gymnos and other more forgiving plants haven't truly drid out all winter and are coming back into growth now as the weather warms up again. Bloody winter!
Next season I may try a few with very light waterings, it must be remembered that I have only had a large collection for about a year and am still learning and trying new things. Been growing cacti for about 7 years though, just not seriously.

| Nice G. cardenasianum, I have one of those, they seem quite hard to get, took me a few years to find just one specimen.
The synonym, for those who didn't know is Gymnocalycium spegazzinii var. cardenasianum.
You have some nice Gymnos lewis, wish I could come across more, I never see them that often.

ah.. yeah i see the problem mate.  i too would be very hesitant to water most my plants in mid-winter if there was no sun available and it was cold at the same time, that seems to be just asking for trouble. even now where i have my plants, in a pretty sunny spot, i only water lightly in the morning of a fine winter's day, so the soil can dry out a little (for more sensitive stuff that is). you don't want to over do it. it's the universal rule of cactus cultivation: if unsure err on the side of underwatering.

yeah..Its a really cool plant, one of my fav gymnos.i love the spines. it is extremely slow growing and quite rare though.
re: Gymnocalycium spegazzinii v. cardenasianum. yeah i im pretty sure that is its' current name. should have stated that... but as with most things cactus-taxonomy-related i prefer the older names... don't know why i just do.  |

2x G. pflanzii and 1 x saglione (furthest right) (now you know what i mean about them being very similar. apart from the heavier spination and more pronounced tubercles/bump ribs on the saglione and the fact it turns red when watered and the pflanzii's don't are the only differences i see). there is a bigger pflanzii to the left of them.. it flowers white with a red centre, with is typical for this species. |

| Cheers HN. I really like my Arios too, I just wish I could find more to buy. There was quite a few going around late last year/early this year, haven't seen too many since, am keen to get some more larger ones soon if anybody is selling
Must get out to Hamilton's, don't have a car though grrr...

| Cheers. Hey I have noticed the oldest head (the wooly one) on the C. hypo looks like it might be cresting or is that just normal growth? Anyone know?
Not that experienced with the species or even the genus.
