Re: Haworthia dormancy

Most Haworthias are going to be tricky in the tropics. There are some summer-growing species, but even they are really set up for hot days and cool nights.

Re: Problems with Nelii

It is very hard to tell whether these are rotting or just preparing to lose the old leaves. If it is rotting, it will go pretty fast. You can save the leaves inside, maybe, by cutting back and re-rooting. Whenever I've tried it, they are very slow. The real answer is sunlight. Oh and "pretty dr...

Re: Windowsill seed raising - Small Cacti and Mesembs

What is that monster in with the Conophytums? A Delosperma? Something even bigger? Might be an idea to evict it pretty quickly. And plant up separately of course :)

Re: Windowsill seed raising - Small Cacti and Mesembs

You can use standard domestic LED bulbs for lighting small areas or starting seeds, just as you can with the twisty tube CFLs or fluorescent tubes, but you won't get one of the main benefits of LEDs which is being highly directional. You're probably going to find CFLs pretty hard to find now or soon...

Re: Propagation of Frilly Echeverias from the Flower Stem

You can propagate Echeverias from any leaf. The trick is getting it to root before the leaf dies since they may not be particularly big or particularly succulent.

Re: Windowsill seed raising - Small Cacti and Mesembs

That's where LEDs have an advantage, they produce light with very little heat. Everyone keeps saying that but it isn't true. LEDs produce more or less the same heat as any other (non-incandescent) light source, comparable to fluorescent tubes, although better than the little compact fluorescents th...

Re: Greenknight 2016

I doubt that Fenestraria of any age died for lack of ones day's misting. Did they overheat? Rot? M. herrerae are supposed to be touchy, but I can't kill them for trying. I'm leaving some out in an unheated greenhouse this year. They're not supposed to be frost-hardy. So far they're doing great, but ...

Re: Advices request for sowing some (winter active) species

So I finally got round to looking up São Carlos climate averages. Oh dear. I don't know how things like Monilaria are going to cope as adults. When they are active they aren't very succulent at all. They wilt badly after a few days in dry soil. Or any days at all if it is sunny! Warm nights are stre...

Re: Windowsill seed raising - Small Cacti and Mesembs

Like all mesembs, you can just chop the stems near the base of the leaves and re-root as a cutting. Some of them seem to take a long time to root, others very quick. It might be that they root very quickly, but only at the right time. For example, Conophytum cuttings root very easily in late autumn....

Re: Advices request for sowing some (winter active) species

Hot summers are not much of an issue for obligate winter growers. The ones that become dry and dormant can tolerate quite extreme temperatures and zero water. Most of them are quite thirsty in winter. A Monilaria that doesn't collapse into dried noodles in summer sounds very strange. Maybe a seedlin...

Re: Windowsill seed raising - Small Cacti and Mesembs

Gibbaeum shandii is another one that looks really nice when grown well, but really nasty in poor light. I got them this far but then they went leggy and etiolated, which I don't have photos of! I should really chop them and go back to nice compact plants. Never had flowers on these.

Re: Windowsill seed raising - Small Cacti and Mesembs

Dactylopsis is an obligate winter grower, in the sense that it is a dead looking lump in the summer. Once new leaves emerge (fingers crossed) in autumn, keep them fat and happy until spring, then let them collapse. Tricky without lots of winter sun. They look great when grown well, but not so great ...

Re: Advices request for sowing some (winter active) species

Welwitschia seedlings obviously don't need a 30cm pot, but they will in a couple of years and they don't like being moved. Same goes for sowing them together, but there probably has to be some concession to practicality. Avonia germinates quickly in hot conditions, but the seed is often not viable. ...
