Re: Root fungus?

What concerns me is what looks like bits of pumice or perlite. In both pictures they are clustered around the base of the plant. As I said, they are
very tiny. Your suggestions of cleaning them off, washing the cactus, inspecting/trimming the roots, and drying it make sense. Thanks.

Root fungus?

I had occasion to dig out from a shallow planter a small Echinopsis ancistrophora ssp arachnacantha that finally died. When I saw the other two E. ancistrophora arachnacantha from the same planter, there were these tiny round things smaller than the head of a pin around the base and in the roots of ...

Re: new Gymno that just bloomed today

Thanks, 'nachtkrabb'. I just checked the site and it looks like it hasn't been active in years. I'm wondering if it's still accepting photos. I realize it's a herculean task!

'Loamy' soil

I have often been confused by the terms applied to cactus soils. I understand mineral and organic soils and, I think, soils with peat vs. peat moss. But when a cactus soil recipe calls for a 'loamy' soil, what exactly does it mean? To me loam has always meant a rich, dark, organic soil. But I know n...

Re: new Gymno that just bloomed today

quehlianum I looked up the listing and yup...bingo! I can explain why I couldn't find it at first when I searched CactiGuide listings. I don't have many hours to spend on cacti per day. I have a nice collection but it's taken years to build. Yes, I've lost many along the way, but I keep trying...an...

new Gymno that just bloomed today

I've searched a couple of pictorial sources for ID on this Gymno I bought locally, but I can't find any exact match. The closest possibilities seem to be G. bodenbenderianum and G. gibbosum v brachypetalum. Even these differ in various aspects. I know there are variations, but nothing else seems to ...

An interesting topic no doubt 🙂 Steve-O wrote; ‘ Was there a better air/soil mix along the pot walls than internally? ‘ I am wondering about the same.

Re: One more Mamm. ID

I'll try to find several photos of that one. I've noticed that often the photos chosen for CactiGuide don't always resemble the descriptions. I think that's what sometimes throws me off. I like to browse here for Mammillaria pictures: https://mammillaria.forumotion.net/f21-mammillarias-a-to-z This ...

Re: One more Mamm. ID

Here's one more name to throw into the mix: M. pullihamata, a form with amber, always hooked spines that has been placed in synonymy with M. rekoi. I'll try to find several photos of that one. I've noticed that often the photos chosen for CactiGuide don't always resemble the descriptions. I think t...

I have a zeilmanniana but it's much taller, and I can't remember how it looked when it was small. But it's a definite possibility. Yes, I guess we'll play the waiting game until it blooms again in the spring.

That looks like a strong possibility although I seem to remember the flowers were more red than pink. But I'll definitely keep it on the list of possibilities for comparing again next spring.

Re: One more Mamm. ID

Some hooked spine Mammillarias are are classified into the alternate genus Cochemiea Thanks for the tip. I checked them out and none look exactly right. The flowers are different than what appeared on mine. Other spination doesn't look just right. Maybe as it matures I'll notice more obvious simila...

One more Mamm. ID

Another one I bought locally. Despite its small size--flattened globular 1.5" diameter--it bloomed with two or three red flowers, fairly large for a cactus this size. Sorry I did not get a picture of them. Using the photo gallery in CactiGuide, I narrowed it down to Mamm. duoformis/fittkaui/gui...
